BACKGROUND:Malaria remains a global public health concern for centuries. The study assessed the knowledge, prevalence and control strategies of malaria among households in the Sunyani Municipality, Bono Region, Ghana.

METHOD:A simple random sampling method was used to administer semi-structured questionnaires to the respondents (n = 422). STATA version 14.0 was used to analyse the data and the results were presented in charts, graphs, and tables.

RESULT:The study shows that the knowledge level of malaria, its vector of transmission and mosquitoes breeding sites among the respondents was quite high. Among the respondents, 43% reported to have been infected by malaria once in a year and 94% indicated that, their relatives have been infected with malaria parasites previously. Also, majority, 65% of the respondents selected environmental management and sanitation (EMS), followed by settlement (building houses) away from wetlands, 20.0% as alternative vector control methods to be employed to supplement the core vector control methods in the Municipality. Further, majority, 69% of the respondents indicated that enforcement of environmental sanitation bye-laws will compel residents to clean their environment, and this is likely to eliminate most mosquito breeding sites, whiles 46% called on Government to support, and employ more Environmental Health Officers and Sanitary Labourers, and adequately resource them to work effectively.

CONCLUSION:Health authorities in the Sunyani Municipality must intensified education on malaria at all levels with the aim to influence the attitudes of households towards its prevention and control. Central and Local Government must employ more Environmental Health Officers, and empower and adequately resourced them to strictly enforce the environmental sanitation bye-laws. Malaria control authorities in the study area must consider employing environmental management and sanitation (EMS) and application of larvicides for mosquito larval control as alternative/supplementary malaria prevention and control methods to compliments the current core vector control methods.

INTRODUCTION: Diversity, equity, and inclusion, also known as DEI, is an essential topic being discussed across society. The field of environmental health (EH) should certainly not be excluded from the conversation.

OBJECTIVE: The purpose of this mini-review was to map the literature and identify gaps on the topic of DEI in the EH workforce.

METHODS: A rapid scoping review was conducted using standard synthesis science methods to search and map the published literature. All study titles, abstracts, and full texts were screened by 2 independent reviewers among the authorship team.

RESULTS: The search strategy yielded 179 English language papers. Of those, 37 met all inclusion criteria after full text screening. Overall, the majority of the articles had weak or moderate DEI engagement and only 3 articles had strong DEI engagement.

DISCUSSION: There is a significant need for additional research in this realm. Future studies should explicitly focus on workforce issues, and attempt to achieve the highest level of the evidence possible for this field.

CONCLUSION: Although DEI initiatives are a step in the right direction, the current evidence suggests that inclusivity and liberation may prove to be more impactful and meaningful constructs to fully advance equity in the EH workforce.

Multiple drug-resistant Escherichia coli (E. coli) is a serious cause of concern, and they can be observed in hospital settings, natural environment, and animals. Dissemination of multiple drug-resistant (MDR) E. coli can pose a high risk to public health. Moreover, they are hard to control with commercial antibiotics, since they have acquired resistance against most of them. Therefore, to control multiple drug-resistant bacteria, alternative strategies have been adopted such as phage therapy, herbal remedies, nanoparticles etc. In the current study, the combined application of neem leaf extract and bacteriophage is used to control an isolated multiple drug-resistant E. coli E1. We have applied 0.1 mg/ml concentration of neem extract in combination with an isolated phage vB_EcoM_C2 of 10¹¹ titer and found that the combinatorial treatment approach significantly controls the growth of E. coli E1 as compared to a single non-combinatorial treatment. In this study, every E. coli cell is targeted by 2 antimicrobials (phage and neem extract) at the same time, which is more effective as compared to the sole treatment. Implementation of the neem extract with phage opens a new alternative approach to the chemotherapeutics for the control of multiple drug-resistant bacterial pathogens. This approach may be effective, economical, and eco-friendly to combat MDR.

BACKGROUND: Schistosomiasis is a highly prevalent but neglected tropical disease, particularly in sub-Saharan Africa. In Ethiopia, urogenital schistosomiasis due to Schistosoma haematobium has been known to be endemic in several lowland areas. This study was designed to determine the current prevalence and intensity of the urogenital schistosomiasis among communities in Kurmuk District, western Ethiopia.

METHODS: Urine filtration technique and urine dipstick test were used to screen for S. haematobium eggs and hematuria, respectively. The data were analyzed with SPSS version 23. Logistic regression and odds ratio were used to measure associations and strength between prevalence, intensity, and independent variables. P-values <.05 at 95% CI were considered statistically significant.

RESULTS: The overall prevalence of S. haematobium infection as determined by urine filtration was 34.2% (138/403). In bivariate analysis, the most infected (45.4%) age groups were 5 to 12years (odds ratio [OR]=4.16, 95% CI: 1.36-12.67), followed by 13 to 20years (OR=3.23, 95% CI: 1.01-10.35) with higher significant mean egg count (MEC). The mean egg intensity ranged from 2.39 in Ogendu (CI: 1.05-3.72) to 14.1 in Dulshatalo (CI: 4.98-23.12) villages. The main predictor of infection was swimming habits (adjusted odds ratio [AOR]=2.43 [CI: 1.19-4.94]). The prevalence of hematuria was 39.2% (158/403), the odds being 2.64times higher among participants who resided in Dulshatalo than those who resided in Kurmuk (AOR 2.64 [95% CI: 1.43-4.87], P=.004).

CONCLUSION: To reduce the infection and interrupt transmission, the PC in place in the area using PZQ should be strengthened and continued, alongside with provision of sanitary facilities, safe alternative water supplies and health education. The Federal Ministry of Health of Ethiopia should also collaborate with the health authorities of the Sudan government for the control of trans-boundary transmission of the disease as the transmission foci are shared between the 2 countries.

Grasscutter (cane rat/Thryonomys swinderianus) digesta is used as a spice in Ghana. Research shows that heavy metals from the environment may accumulate in the internal organs of grasscutters, which raises concerns about the possible contamination of grasscutter digesta, too, with heavy metals. Although grasscutter meat in Ghana has been described as safe for consumption, information is lacking on the health risks associated with ingesting the digesta. This study, therefore, aimed to assess the knowledge and perceptions of a merchant and a consumer about the safety of ingesting grasscutter digesta and to evaluate potential health risks from exposure to heavy metals from the spice. A total of 12 digesta samples were analyzed to evaluate potential health risks from exposure to Cd, Fe, Hg, and Mn using a Varian AA240FS Atomic Absorption Spectrometer. The levels of Cd, Hg, and Mn were below the detection limit of 0.01 mg/kg digesta. Also, the estimated daily intake of Fe (0.02 mg/kg) was less than the maximum allowable dose recommended by the US EPA (0.7 mg/kg). The hazard indices of Fe for daily and weekly consumption were <1, suggesting that the consumers may be safe from iron poisoning. Because grasscutter digesta is a relatively expensive spice, it is unlikely to be consumed daily by the average Ghanaian. Moreover, if 10 g of digesta is consumed daily, it can be safely ingested about 971 times in a month. Domestication of grasscutters may be a useful approach to monitor their diet and consequently the quality of their digesta.

BACKGROUND: Artisanal and Small-scale Gold Mining (ASGM) is widely practiced in Ethiopia. Injuries are among the public health concerns in the mining sector. This study aimed to assess the prevalence of nonfatal occupational injuries and associated factors among workers in ASGM in Ethiopia.

METHODS: A cross-sectional study design was employed from April to June 2020. A total of 403 participants were selected with a simple random sampling technique. A structured questionnaire was utilized for the data collection. Descriptive statistics were used to characterize the information and binary logistic regression was applied to test the association. Predictor variables with P-value < .05 with an Odds ratio of 95% CI in multivariable analysis were considered as associated factors.

RESULTS: A total of 403 participants were interviewed with a response rate of 95.5%. The prevalence of nonfatal occupational injury was 25.1% in the past 12 months. About one-third of the injuries, 32 (31.7%), were on the upper extremity and feet, 18 (17.8%). Symptoms of mercury toxicity (AOR: 2.39, 95% CI [1.27-4.52]), 1 to 4 years of work experience (AOR: 4.50, 95% CI [1.57-12.9]), full work shift (AOR: 6.06, 95% CI [1.97-18.7]), and job in the task of mining activities (AOR: 4.83, 95% CI [1.48-15.7]) were associated with the injury.

CONCLUSION: A substantially high prevalence of injuries was observed. Work-related factors were found to be significantly associated with the occurrence of injury. The government body, mining sector, and workers are advised to apply interventions focusing on the improvement of working conditions and safety practices to minimize injury.

BACKGROUND: Despite global interventions to prevent and control diarrhea, it remains a public health problem leading to childhood morbidity and mortality majorly in developing countries. According to the World Health Organization, data from 2021 indicated that diarrheal disease is responsible for 8% of deaths in children under the age of 5. In the world, more than 1 billion under-five children live in poverty, social exclusion, and discrimination affected by intestinal parasitic infections and diarrhea disease. In sub-Saharan African countries like Ethiopia, diarrheal diseases and parasite infections continue to cause significant and persistent morbidity and mortality in under-five children. Therefore, the purpose of this study was to assess the prevalence and associated factors of intestinal parasites and diarrheal diseases in children under the age of 5 years in Dabat District, Northwest Ethiopia in 2022.

METHOD: A community-based, cross-sectional study was carried out from September 16 to August 18th 2022. Four hundred households with at least one child under the age of 5 years were recruited by simple random sampling technique. Sociodemographic, clinical, and behavioral factors were also collected using pretested interviewer-administered questionnaires. Data was entered into Epi-data version 3.1 and exported to Statistical Package for Social Science (SPSS) version 25 for analysis. Binary logistic regression was performed to identify factors associated with diarrhea and intestinal parasitic infections. The level of significance was computed at a P-value ⩽ .05. Descriptive statistics such as frequency and other summary statistics were used for describing sociodemographic variables and determining the prevalence of diarrhea and intestinal parasites. Tables, figures, and texts were used to present the findings. The variables having a P-value of less than .2 in the bivariable analysis were entered into the multivariable analysis at a P-value of ⩽.5.

RESULTS: According to this study, the prevalence of diarrhea and intestinal parasites among under-five children was 20.8% (95% CI: [16.8-37.8] and 32.5% (95% CI: [28.6, 37.8], respectively. In multivariable logistic analysis at a P-value of ⩽.5, the educational level of mothers (Adjusted odds ratio [AOR]: 3.7, 95% CI: [1.52, 8.95], residence (AOR: 4.7, 95% CI: [1.52, 8.09]), undernutrition (AOR: 3.6, 95% CI: [1.09, 11.3]), latrine availability (AOR:3.9, 95% CI: [1.23, 9.56]), types of the latrine (AOR: 5.9, 95% CI: [3.42, 11.66]), water treatment (AOR = 7.6; 95% CI: [6.4, 12.7]), eating uncooked vegetable or fruits (AOR = 4.6; 95% CI: [1.025, 15.2]), and source of water (AOR = 4.5; 95% CI: [2.32,8.92]) were significantly associated with diarrheal disease. Intestinal parasitic infection was also significantly associated with undernutrition (AOR = 3.9; 95% CI: [1.09, 9.67]), latrine availability (AOR = 2.1; 95% CI:[1.32, 9.32]), types of the latrine (AOR = 2.8; 95% CI: [1.92, 8.12]) residence (AOR = 4.7; 95% CI: [1.52, 8.09]), water treatment, source of water for drinking (AOR = 4.5; 95% CI: [2.32, 8.92]), eating uncooked vegetables or fruits (AOR = 6.7:95% CI: [3.9, 9.8]), and deworming children with anti-parasitic medication (AOR = 2.4; 95% CI: [1.34, 5.62]), washing hands after latrine used (AOR = 2.2: 95% CI: [1.06, 3.86]).

CONCLUSION: The prevalence of diarrhea and intestinal parasite among under-five children was 20.8% and 32.5%, respectively. Undernutrition, latrine availability, types of latrines, residence, eating uncooked vegetables or fruits, and source of water for drinking and water treatment were associated with intestinal parasitic infection and diarrheal disease. Deworming children with antiparasitic medications and washing hands after latrine use was also significantly associated with parasitic infection. Hence, awareness creation activities on latrine utilization and building, keeping personal hygiene, safe water supply, feeding cooked vegetables or fruits, taking anti-parasitic medications, practice hand washing habit after toilet use are strongly recommended.

BACKGROUND: Approximately 1.9 million people worldwide are blind or visually impaired due to trachoma, and trachoma remains endemic in 44 countries. Amhara in Ethiopia has the highest burden of trachoma in the world. A key indicator of whether active trachoma requires public health intervention is the incidence of trachomatous inflammation-follicular in children aged 1 to 9 years. However, limited study has been conducted on the determinants in rural communities. This study therefore aimed to fill this gap by identifying determinants in the Gozamn district of northwestern Ethiopia.

METHODS: A community-based case-control study was carried out between March 15 and April 30, 2021. Five or more follicles on the epitaxial conjunctivae that are larger than 0.5 mm were considered a case. Controls were free of any sign of trachoma. A semi-structured questionnaire and an observational checklist were used to gather the data, and STATA version 14 was used for the analysis. Using a 95% confidence interval, both bivariable and multivariable conditional logistic regression was performed.

RESULTS: A total of 726 mothers/caregivers participated in this study, with a participation rate of 98.4%. Children from poor families (mAOR = 4.68; CI: 2.80-6.21), households where the water source is far from home (>30 minutes) (mAOR = 4.91; KI: 1.37-12.56), mean daily water consumption (<20 l/c/d) (mAOR = 4.42; CI:1.71-11.39), face washing frequency less than once a day (mAOR = 10.64; CI: 2.58-18.84), cloth washing frequency once a month or less (mAOR = 9.18; CI: 2.20-18.62), and mothers or caregivers with poor knowledge of active trachoma (mAOR = 3.88; CI: 1.47-10.22) were determinants of trachomatous inflammation-follicular.

CONCLUSIONS: We conclude that infrequent faces and clothes washing; unavailability of water, children in poor families, and poor knowledge of mothers/caregivers were risk factors. Health education initiatives about active trachoma, its prevention, and control methods focusing on personal hygiene are so required.

BACKGROUND: Street food is expanding all around Ethiopia. Street vendors have become commonplace near schools, hospitals and bus stations. Because street vended food is sold in unsanitary surroundings near streets, it can be contaminated with variety of pathogens, exposing consumers to foodborne illnesses. There haven’t been enough studies on Ethiopian street food, and little is known about how hygienic these foods are. The local authorities don’t even have a regulatory system to ensure food safety for street food vendors. Thus, this study aimed to assess food hygiene practices among street food vendors and associated factors.

METHODS: Community-based cross-sectional analytical study design was conducted from June, 2021 to July, 2021 including 402 respondents. Structured questionnaire and observational checklists were used for assessing food hygiene practices. Data were analyzed using SPSS statistics (version 25.0). Binary logistic regression analyses were used to check association of covariates with food hygiene practices. Adjusted odds ratio, and P-value less than 0.05 at 95% confidence interval were used to report significant association.

RESULTS: Out of 402, 390 individuals responded. About 123 (31.5%) (95% CI: 27.2-36.4) of vendors had good food hygiene practices. Being female (AOR = 0.15; 95% CI: 0.09-0.27), age (19-25 years (AOR = 0.29; 95% CI: 0.11-0.81) and 26 to 35 years (AOR = 0.24; 95% CI: 0.08-0.74), marital status (being married (AOR = 0.52; 95% CI: 0.29-0.93), educational status (college and above (AOR = 3.42; 95% CI: 1.35-8.62), monthly income (1001-2000 Ethiopian Birr (AOR = 0.36; 95% CI: 0.19-0.68), being inspected (AOR = 13.15; 95% CI: 2.76-62.66) and lack of water at vending site (AOR = 0.40; 95% CI: 0.17-0.97) were factors significantly associated with food hygiene practices of street vendors.

CONCLUSION: Few street food vendors who adhered to good food hygiene were present. Significant variables of food hygiene behaviors included gender, age, marital status, education level, monthly income, inspection frequency, and the availability of water at vending sites. The vendors’ food hygiene practices needed to be improved, which necessitated continual assistance, frequent inspections, and public awareness campaign.

BACKGROUND: Food safety has emerged as one of the 10 threats to global health. Ethiopia is among the developing countries with many food industries in recent times. Poor food handling procedures, a lack of basic infrastructure, lack of potable water, lack of financial resources to invest in safer equipment, and lack of training for food handlers have all been reported.

OBJECTIVES: To assess food safety practices and associated factors among food handlers working in food industries in Bahir Dar city administrations.

METHODS: A cross-sectional study was conducted from January to February 2021 among 422 food handlers working in food industries in Bahir Dar city, Ethiopia. A random sampling technique was used to select food industries and study participants. The sample size was proportionately allocated to the selected food industries. Data were collected through face-to-face interviews and observation methods using interviewer-administered questionnaires and an observational checklist respectively. Data was entered into Epi-data v 3.1 and exported to SPSS v 23 for analysis. Bi-variable binary logistic regression was carried out to identify candidate variables at p-value <.2 and was entered into the final multivariable binary logistic regression model to control the effect of confounding. Variables with p-values of less than .05 were declared as statistically significant and an odds ratio of 95% CI was used to measure the strength of the association.

RESULT: Food safety practice among food handlers working in food industries was 47.6% (95% CI: 42.8, 52.5). Sex [AOR: 2.92 (CI: 1.77, 4.82)], monthly salary [AOR: 2.02 (CI: 1.18, 3.44)], health supervision [AOR: 3.43 (CI: 1.97, 5.97)], working unit [AOR: 2.44, (CI: 1.45, 4.13], food safety training [AOR: 6.16 (2.97, 12.77)], attitude [AOR: 3.55 (CI: 1.14, 11.05)] were factors significantly associated with food safety practice.

CONCLUSION: Food safety practice among food handlers was low. Sex, working unit, monthly income, regulatory supervision, food safety training, and attitude toward food safety were factors associated with poor food safety practices. In-service training on good hygiene practices, good manufacturing practices, hazard analysis, critical control point, food safety management systems, and supportive supervision should be strengthened.

BACKGROUND AND OBJECTIVE:There have been significant effects of the current coronavirus-19 (COVID-19) infection outbreak on many facets of everyday life, particularly the environment. Despite the fact that a number of studies have already been published on the topic, an analysis of those studies’ findings on COVID-19’s effects on environmental pollution is still lacking. The goal of the research is to look into greenhouse gas emissions and air pollution in Bangladesh when COVID-19 is under rigorous lockdown. The specific drivers of the asymmetric relationship between air pollution and COVID-19 are being investigated.

METHODS:The nonlinear relationship between carbon dioxide (CO₂) emissions, fine particulate matter PM_2.5 and COVID-19, as well as its precise components, are also being investigated. To examine the asymmetric link between COVID-19 factors on CO₂ emissions and PM_2.5 we employed the nonlinear autoregressive distributed lag (NARDL) model. Daily positive cases and daily confirmed death by COVID-19 are considered the factors of COVID-19, with lockdown as a dummy variable.

RESULTS:The bound test confirmed the existence of long-run and short-run relationships between variables. Bangladesh’s strict lockdown, enforced in reaction to a surge of COVID-19 cases, reduced air pollution and dangerous gas emissions, mainly CO₂ according to the dynamic multipliers graph.

BACKGROUND: Consistent latrine utilization remains a challenge in most rural areas of poor and middle-income countries including Ethiopia. Therefore; the objective of this study was to determine the magnitude of latrine utilization and its associated factors among rural households in open defecation-free declared (ODF) and non-ODF kebeles, Southwest Ethiopia, 2022.

METHODS: A community-based comparative cross sectional study design was employed from May 16 to June 14, 2022 among 682 (341 ODF and 341 non-ODF) rural households which were selected by multistage systematic random sampling technique. Data were collected by face to face using a pretested structured questionnaire and an observational checklist through Open data kit. SPSS version 26 was used to analysis the data and separate logistic regression models; ODF and non-ODF were run to identify the associated factors. P-values <.05 with 95% CI were set as statistical significant.

RESULT: The overall magnitude of latrine utilization in the study area was 67.1% (95% CI: 63.71, 70.49). Latrine utilization was higher in ODF declared households (71.6%) than in non-ODF households (62.5%). In ODF; Graduated as model households [AOR = 5.1, 95% CI: 2.14, 12.84], visited by health extension works (HEWs) [AOR = 3.5, 95% CI: 1.67, 7.25], and latrine with privacy [AOR = 3.0, 95% CI: 1.37, 6.65] and also in non-ODF; households visited by HEWs [AOR = 2.9, 95% CI: 1.34, 6.06], latrine with privacy [AOR = 2.5, 95% CI: 1.24, 5.07], positive attitude [AOR = 3.2, 95% CI: 1.52, 6.59], and descriptive norm [AOR = 2.7, 95% CI: 1.27, 5.53] were significantly associated with latrine utilization.

CONCLUSION: This study found that rural households declared as ODF utilize their latrine higher than non-ODF. Constructing latrine without privacy, lack of follow up, Attitude and societal norms were factors that limited the utilization of latrine and the sustainability of ODF. Therefore, health extension follow-up, latrine construction with privacy, normative and persuasive behavior change approach should be encouraged.

Freshwater bodies such as lakes, rivers, and their biodiversity are being threatened with water pollution from industrial effluents and household sewages. The main objective of this study is to assess the effects of wet coffee processing plants effluent on the physicochemical and bacteriological properties of receiving rivers. Four rivers and 4 sampling points of the selected rivers were included in the study. Focus group discussion and interview were employed to gather primary data. The result showed that parameters of water quality for downstream of the rivers were significant, particularly in the dry season with BODs ranging from 45 ± 1 to 782.6 ± 97 g/ml, COD ranges from 71 ± 21 to 1072 ± 183 g/ml, Conductivity ranges from 75.5 ± 6.6 to 943 ± 56.3, Turbidity ranges from 7 ± 0.43 to 105 ± 6.2, TDS ranges from 62 ± 6.4 to 1059.6 ± 121 g/ml, temperature ranges from 20.1 to 33 ± 1, T. coli form ranges from 77 ± 1.1 to 493 ± 66 and E. coli ranges from 28 ± 1 to 213 ± 41 were significantly higher and DO ranges from 2.6 ± 0.15 to 6.1 ± 0.78 g/ml, NH₄ ranges from 1.85 ± 0.4 to 3.3 ± 0.5 g/ml, and pH ranges from 3.6 ± 0.2 to 7.3 ± 0.45 were significantly lower. Most of the samples taken from wastewater and downstream parts of the river showed high level of water contaminants that are significantly greater than the EEPA discharge limits for surface water. Moreover, the qualitative data indicated that the community was affected by bad smell and color change on rivers, skin irritation, malarial case in human due to coffee processing plant effluents. Therefore, coffee processing plants should treat their effluents before they discharge it into the rivers. Responsible government bodies should authorize activities of coffee processing plants in line with the regulations set for environmental safety.

INTRODUCTION: Insecticide-treated nets (ITNs) are widely used tools that have been proven effective in preventing and controlling malaria. However, usage varies among households and can greatly affect the benefits of ITNs. Thus, this study aimed to assess the household utilization of insecticide-treated nets and its associated factors for under-5 children.

METHODS: A cross-sectional study was conducted in March-April 2020 in the East Mesekan district. A total of 591 households with under-5 children were chosen by using a systematic random sampling approach for the interviews. The data was collected using a pretested questionnaire. Epi-Data version 3.1 was used to enter data and SPSS version 21 for analysis. A P-value of .05 was considered statistically significant.

RESULTS: In this study, 58.2% (95% CI: [54.1%-62.2%]) of household participants used ITN for children under 5 years of age while sleeping the night before the survey. The study participants’ overall knowledge and practice of malaria prevention were 27.1% and 23.9%, respectively. Having a family size of less than 5 (AOR = 0.60, 95% CI: [0.37-0.98]) and complaints of skin irritation (AOR = 0.43, 95% CI: [0.29-0.63]) significantly decreased ITN utilization. However, having 1 ITN (AOR = 2.15, 95% CI: [1.15-4.02]) or 2 ITNs (AOR = 2.58, 95% CI: [1.51-4.39]), as well as low (AOR = 2.07, 95% CI: [1.33-3.20]) and medium (AOR = 1.83, 95% CI: [1.11-3.02]) knowledge of ITN importance, increased ITN utilization significantly.

CONCLUSIONS: The households’ use of ITNs for children under the age of 5 was inadequate. It was significantly associated with having a family size of less than 5, complaints of skin irritation, owning 1 or 2 ITNs, and having low and medium knowledge of its importance. It is recommended that continuous and progressive health awareness about the consistent use of ITN for malaria prevention in the study area be promoted.

BACKGROUND: Cysticercus bovis has zoonotic implications with economic losses from organ contamination and treatment costs. In developing countries such as Ethiopia, where hygienic standards are low and residents customarily eat raw or undercooked meat, the disease is prevalent.

METHODS: A cross-sectional study was carried out from December 2021 to June 2022 to determine the prevalence of Cysticercus bovis in cattle slaughtered at the Bishoftu municipal abattoir, in central Ethiopia. Study populations for the active abattoir survey were cattle presented to the abattoir for slaughtering and routine meat inspection conditions. The organ namely the tongue, masseter muscle, liver, and triceps muscle were inspected for the presence of C. bovis.

RESULTS: From a total of 330 cattle, 14 were found to be positive for C. bovis, with an overall prevalence of 4.24%. Based on the origin of the animals, the highest prevalence was recorded at Adama (7.27%), followed by Bishoftu (5.45%), Mojo (5.45%), Borana (3.63%), Dukem (3.63%), and Kaliti (0.00%). Similarly, out of 111 adults and 219 old-aged cattle slaughtered and examined at the abattoir, 4.5%, and 4.11% were positive for C. bovis, respectively. Among tested independent variables, sex, body condition score, age, and origin of animals had no relationships with the prevalence of C. bovis. From the detected organ, the tongue ranks first for the highest number of cysts, followed by the masseter muscle, liver, and triceps muscle, with total cysts of 6, 4, 3, and 1, respectively.

CONCLUSION: C. bovis is a prevalent zoonotic parasite disease that causes carcass condemnation; an enhanced understanding of the health consequences of teniasis is required to protect the community.

BACKGROUND: Schistosoma mansoni is endemic in all regions of Ethiopia. School-age children are highly vulnerable to schistosomiasis-related morbidities. This study aimed to determine the prevalence of S. mansoni and morbidities among schoolchildren in schistosomiasis hotspot areas of Jimma Town.

METHODS: Cross-sectional study was conducted among schoolchildren in Jimma Town. Stool sample was examined using Kato-Katz for the detection of S. mansoni.

RESULTS: A total of 332 schoolchildren were included in the study. The prevalence of S. mansoni and STHs was 20.2% and 19.9%, respectively. Males (adjusted odds ratio (AOR) = 4.9; 95% CI: 2.4-10.1; p = .001), swimming habits (AOR = 3.0; 95% CI: 1.1-8.3; p = .033) and schools attended (AOR = 4.3; 95% CI: 1.4-13.6; p = .012, AOR = 3.8; 95% CI: 1.3-10.9; p = .014) were associated factors for S. mansoni infections. Blood in stool (AOR = 2.0; CI: 1.0-4.1; p = .045) and feeling general malaise (AOR = 4.0; CI: 1.4-11.3; p = .007) were significantly associated with S. mansoni infection-related morbidities. Moreover, prevalence of stunting among schoolchildren 6 to 11 years of age was 29.7% (71/239).

CONCLUSION: The transmission of S. mansoni among schoolchildren is moderate. Sex, swimming habits and schools attended were associated with S. mansoni infections. Blood in stool and general malaise were clinical characteristics associated with S. mansoni infections. Integration of health promotion is needed to achieve control and elimination goals. Attention should also be given to stunted growth of the children.

Metals and metalloids pollution of Ethiopian surface water is becoming an environmental issue. Bioaccumulation and Biota-Sediment Accumulation Factor (BAF and BSAF) are used to quantify the bioaccumulation of contaminants from water and sediment to biota. The present study aimed to determine the BAF and BSAF of metals and metalloids in different surface waters of Ethiopia. Furthermore, the ecological and human health risks were also examined. Generally, 902 peer-reviewed papers from 2005 to 2022 were searched using search engines. The most common types of edible fish species in studied surface waters of Ethiopia were Oreochromis niloticus, Clarias gariepinus, and Barbus intermedius. The concentration of metals and metalloids were higher in sediment than in water and in carnivorous fish than in herbivorous fish. The BSAF of Se in all fish species was greater than 1. Oreochromis niloticus was a bio-concentrator of As and Se. The dissolved concentration of Cu, Cd, Pb, and Ni were higher compared to the Ethiopian Environmental Protection Authority and the European Union; Organization of Economic and Co-Operation Development environmental water quality standard guidelines for inland surface freshwater bodies. Likewise, in sediment, the concentration of Cu, Pb, Ni, Zn, and Cr were above Tolerable Effect Concentration values and Cd, Ni, and Cr were above Probable Effect Concentration levels when compared to the United States Consensus-Based Sediment Quality Guidelines for freshwater which indicates that these metals may pose risk to aquatic organisms. Consumption of raw water and fish contaminated with the detected metals and metalloids is not associated with any diseases. However, local consumers who live close to each freshwater ecosystem may become more exposed to health risk hazards. The findings of this study will provide baseline information on BAF and BSAF of metals and metalloids in surface waters and will contribute to the effective monitoring of environmental quality.

In Ethiopia, like that of the other developing countries, pesticides are widely used for a variety of purposes, but their unsafe use causes a major environmental and health hazard. The aim of this study was to assess pesticide use practice and its associated factors among the rural community of Malga district, Sidama region, southern Ethiopia. A community based cross-sectional study was conducted from February to March 2021 at Malga District. Data were collected from 549 farmers by a structured and pretested interviewer-administered questionnaire. Binary and multivariable logistic regression was used for the data analysis. Adjusted odds ratios and their 95% confidence intervals (CIs) were calculated to determine the association between safe practices of pesticide use and several related factors. Safe practice of pesticide use was observed in 193 (35.2%). The participants who had primary education [AOR = 5.605, 95% CI: 3.309, 9.495], secondary education and above [AOR = 9.847, 95% CI: 5.007, 19.368], used pesticide for 10 years and above [AOR = 6.790, 95% CI: 3.589, 12.843], used pesticide between 6 and 10 years [AOR = 1.913, 95% CI: 1.166, 3.141] pesticide bought from any shop [AOR = 2.320, 95% CI: 1.364, 3.947], agricultural office [AOR = 7.187, 95% CI: 3.654, 14.137] were associated with safe use of pesticides. The safe practice of pesticide use was low in the study area. Continuous training programs should be implemented on the safe practice of pesticide use to the local farmers.

The quality of drinking water is an important health issue in crowded cities, so that an adequate drinking water with good quality must be provided, hence over hundreds of water coolers are distributed in Makkah city to cope with the increasing demand for drinking water. The present study aimed to determine the chemical and microbial quality of drinking water from coolers in Makkah city. Sixty-three samples from randomly selected water coolers were tested for chemical and bacteriological quality. For all samples, the mean value of physiochemical tests of pH (7.12), TDS (152.7 ppm), turbidity (2.56 NTU), free chlorine (0.312 ppm), fluoride (0.112 ppm), chloride (25.7 ppm), bromide (0.123 ppm), nitrate (0.616 ppm), sulfate (8.36 ppm), lithium (0.134 ppm), sodium (17.6 ppm), potassium (1.42 ppm), magnesium (1.95 ppm), calcium (19.2 ppm), chromium (0.025 ppm), cadmium (0.0026 ppm), and lead (0.0244 ppm) did not exceed the reference values of the drinking water regulations. The total coliform count was detected in 3.2% of the water samples. For total coliform count, the MPN in the majority of water samples (96.8%) was excellent while for E. coli count, the MPN in all water samples (100%) was excellent. Bacteriological quality has shown that no Pseudomonas, Salmonellae, or Legionellae species contamination detected. It was concluded that, the drinking waters in coolers in Makkah city were complied with international standards and within the acceptable limit. It is worth to continue periodic inspection and maintenance for the drinking water coolers during mass gatherings.

On-site sanitation is the most popular sanitation option for households in many African countries, including Ethiopia. Despite the option being common, there are challenges attributed to the sustainability of those facilities. This community-based exploratory study aimed to explore the challenges in the provision of safe urban on-site sanitation in Jimma town, Ethiopia. Data were collected through key informant semi-structured interviews, transit walks through the village, and focus group discussion (FGD). The FGD was audio recorded and notes were taken by experts. Records and notes were transcribed separately and thematically analyzed. Three major themes or challenges were discovered. Accordingly, the first theme was the community’s perception and taboos surrounding human waste. The second theme was urban land use and informal settlements. Ensuring standards separately for sanitation facilities is difficult because of the expansion of illegal settlements. The third theme was poor sanitation planning, operation and maintenance, and institutional setting. Urbanization without infrastructure generally has a complex nature that leads to a fragile sanitation situation in the future. The results suggest the need for multi-dimensional system development and a collaborative sanitation master plan. Furthermore, interventions aimed at breaking the taboo on human waste as a sanitation platform may turn challenges into opportunities.

Parasitic and microbial contamination and the pattern of occurrence of the parasite species depends on weather conditions, socio-cultural conditions, sampling season, analyzed vegetable products, and other factors. Therefore, local assessment of vegetable contamination is crucial for targeted and effective interventions. A cross-sectional study was conducted from February to August 2022. A questionnaire was used to assess factors associated with parasite contamination of vegetables during the marketing period. The selected vegetables were purchased and processed for parasite and microbial analysis using standard methods. Finally, all data were summarized and analyzed using SPSS software version 25. A total of 180 vegetable samples were purchased from 180 vendors. This study identified a total of 129 parasites from 180 vegetable samples, with an overall contamination rate of (75; 41.7%). Both protozoa (41; 31.8%) and helminthes (88; 68.2%) were identified from vegetables. Contamination with more than one parasite species was (38; 21.1%). The kind of produce, finger nail status of vendors/sellers, the medium of the display, the type of market and not washed prior to display were significantly associated with parasite contamination. The results also showed that vegetable microbial load for total heterotrophic count, total coliform count, fecal coliform count, yeast count, and mold count was higher in the afternoon than in the morning. To decrease risks to public health, local health authorities and/or market inspectors should establish and implement strategies to reduce contamination such as encouraging specific display medium and washing of vegetables prior to display.

Sustainable economic development involves both improving the socio-economic quality of life in the present and improving environmental conditions for future generations. The main objective of the study was to investigate the impact of the determinant macroeconomic variables, including economic complexity, construction, energy consumption, and housing sector expenditures, on environmental changes in Iran over the period 1991 to 2019; using the autoregressive distributed lag (ARDL) model. The results show that at the macro level, an increase in the economic complexity index can reduce pollution in both the short and long term. The effects of further expansion of the housing sector and household energy consumption on pollution are positive and significant in both the short and long run. The error correction model (ECM = 0.65) shows that 65% of the imbalances in each period are corrected in the next period. Based on the obtained results, it is recommended to take serious measures to improve the structure of production and increase the country’s economic complexity index; in other words, to produce goods with higher knowledge and technology and apply policies to improve the level of household energy consumption leading to air pollution reduction.

BACKGROUND: We aimed to evaluate the impact of heatwaves on daily deaths due to non-accidental, cardiovascular and respiratory causes in the city of Dezful in Iran from 2013 to 2019.

METHOD: We collected daily ambient temperature and mortality and defined 2 types of heatwaves by combining daily temperature ⩾90th in each month of the study period or since 30 years with duration ⩾2 and 3 days. We used a distributed lag non-linear model to study the association between each type of heatwave definition, and deaths due to non-accidental, cardiovascular and respiratory causes with lags up to 13 days.

RESULTS: There was no discernible correlation in this area, despite the fact that heatwaves raised the risk of death from cardiovascular causes and lowered the risk from respiratory causes. On the other hand, the risk of total non-accidental mortality on days with the heatwaves is significantly higher than normal days. In main effects, the heatwaves have a significant relationship with the risk of total non-accidental mortality (in the first heatwave definition, Cumulative Excess Risk (CER) in lag_0-2 was 10.4 and in second heatwave definition, CER values in lag_{0, 0-2, and 0-6} were 12.4, 29.2, and 38.8 respectively). Also, in added effects, heatwaves have a significant relationship with the risk of total non-accidental mortality (in the first heatwave definition, CER in lag_{0 and 0-2} were 1.79 and 4.11 and in the second heatwave definition, CER values in lag_{0, 0-2, and 0-6} were 7.76, 18.35 and 24.87 respectively). In addition, heatwaves appeared to contribute to a cumulative excess risk of non-accidental death among the male group as well as the older adults.

CONCLUSION: However, the results showed that heatwaves could have detrimental effects on health, even in populations accustomed to the extreme heat. Therefore, early warning systems which monitor heatwaves should provide the necessary warnings to the population, especially the most vulnerable groups.

In recent decades, paying attention to bisphenol A (BPA), as one of the endocrine disruptor compounds, has increased due to its harmful effects. Although, scattered studies have been conducted in order to measure BPA concentration migrated into polymeric baby bottles in different countries of the world, there are no review studies and evaluation with a global perspective in the field of BPA risk. Some of these studies indicated the potential risks and estrogenic effects associated with BPA in babies’ daily intake. For this purpose, we reviewed the information on the migration levels of BPA into baby bottles has been reported in 10 countries. The potential risks associated with BPA through the daily intake as well as the estrogenic effect on 3 age groups of babies which include 0 to 6, 6 to 12, and 12 to 24 months were analyzed using the Monte Carlo simulation. Also, kinetic models were applied to predict the kinetics of the migration process of BPA. The median daily intake for 3 age groups was obtained as 191.1, 161.37, and 153.76 µg/kg/day, respectively; which indicated Hazard Index (HI) > 1. The median estrogenic effect for the 3 groups was estimated to be 0.021 ngE₂/L. The kinetics of contaminant transfer with Polynomial model at 2 temperatures of 24°C and 40°C showed a better fit with R² = 0.99 and 0.91, respectively. Based on the risk assessment analysis conducted in the present study, the BPA migration in baby bottles appeared to be a health concern for babies. Therefore, it is needed to increase the safety level of bottles for babies as they are sensitive and vulnerable members of every society. Furthermore, in this study, only the investigation of the global situation of BPA in polymeric baby bottles was stated; therefore, more investigation about another potential sources of BPA in food chain is needed.

OBJECTIVE:Coronavirus-19 (COVID-19) outbreaks have been reported in a range of climates worldwide, including Bangladesh. There is less evidence of a link between the COVID-19 pandemic and climatic variables. This research article’s purpose is to examine the relationship between COVID-19 outbreaks and climatic factors in Dhaka, Bangladesh.

METHODS:The daily time series COVID-19 data used in this study span from May 1, 2020, to April 14, 2021, for the study area, Dhaka, Bangladesh. The Climatic factors included in this study were average temperature, particulate matter (PM_2.5), humidity, carbon emissions, and wind speed within the same timeframe and location. The strength and direction of the relationship between meteorological factors and COVID-19 positive cases are examined using the Spearman correlation. This study examines the asymmetric effect of climatic factors on the COVID-19 pandemic in Dhaka, Bangladesh, using the Nonlinear Autoregressive Distributed Lag (NARDL) model.

RESULTS:COVID-19 widespread has a substantial positive association with wind speed (r = .781), temperature (r = .599), and carbon emissions (r = .309), whereas PM_2.5 (r = −.178) has a negative relationship at the 1% level of significance. Furthermore, with a 1% change in temperature, the incidence of COVID-19 increased by 1.23% in the short run and 1.53% in the long run, with the remaining variables remaining constant. Similarly, in the short-term, humidity was not significantly related to the COVID-19 pandemic. However, in the long term, it increased 1.13% because of a 1% change in humidity. The changes in PM_2.5 level and wind speed are significantly associated with COVID-19 new cases after adjusting population density and the human development index.

Air pollution resulting from the use of unhealthy/unclean energy sources for cooking causes illnesses such as lung cancer, stroke, chronic obstructive pulmonary disease and ischaemic heart disease. In Ghana, each year, about 18 000 deaths are recorded due to the use of unhealthy energy sources for cooking. While financial inclusion can influence the adoption of healthy energy sources for cooking, less attention has been paid to it. This study, therefore, investigates the effect of financial inclusion on the choice of healthy source of energy for cooking among households in Ghana. Doing so reveals whether financial inclusion can be employed as a tool to decrease the use of unhealthy sources of energy for cooking in Ghana. We employ the Ghana Living Standards Survey round 7 (GLSS7) as the data source for the study whiles the binary logistic regression is used as the estimation technique. The findings show that, households with financial inclusion (using a single indicator) are more likely to choose healthy sources of energy for cooking relative to those without financial inclusion (OR = 2.52, P < .01). Moreover, the effect of financial inclusion (using a single indicator) on choosing a healthy source of energy for cooking is greater among rural households (OR = 3.18, P < .01) relative to their urban counterparts (OR = 2.27, P < .01). The findings are robust even after using a different estimation technique and a combined index of financial inclusion. Thus, in the quest to improve the use of healthy sources of energy for cooking, enhancing financial inclusion among households, could be a useful strategy.

The radiation dose from internal radiation exposure is difficult to measure directly and hence different lung models were developed. The dose on the lung is the result of the regional deposition of aerosols carrying radon daughters in the respiratory tract. Deposition of aerosols can be take place during inhalation and exhalation in the 5 regions of the respiratory tract due to variation of aerosol sizes and other biological factors such as breathing rate. In this paper, a modified breathing rate is instead applied on the assumptions developed by the ICRP66 model to analyze the regional deposition of radioactive aerosols and a comparison has been made with the result of ICRP66 model deposition. According to the result, as the diameter of aerosols increases from 1 to 10 µm, the percentage deposition fraction in extrathoracic regions, in ET1 region increases from 6.53% to 48.43% and in ET2 region increases from 7.3% to 50.33%. The aerodynamic deposition of the attached fraction of radon aerosols along the bronchial regions (bronchi (BB), and bronchiolar (bb) region) is found small and almost constant. For 1 µm diameter aerosols, the percentage deposition is found 0.82%, for 5 µm diameter aerosols, the deposition is predicted 2.56% and at 10 µm the deposition is predicted about 1.93% in bronchi (BB) region. In the bronchiolar region (bb) for 1 µm aerosols, the deposition predicted is 1.5% and at 10 µm about 0.88% is predicted. The deposition of small size attached fraction of radon aerosols is found maximum in the alveolar region as compared to other regions of the respiratory tract and the deposition becomes almost negligible for large size aerosols in this region.

The lack of diversity among the environmental health sciences (EHS) workforce has been an ongoing concern. However, limited research exists on the racial and ethnic composition of EHS students and faculty over time. We analyzed 2011 and 2021 data on EHS students, graduates, and faculty to compare changes in the racial and ethnic composition among Association of Schools and Programs of Public Health-member institutions. Among the institutions that reported data in both years, we observed significant proportion increases among Hispanic enrolled students (overall and master’s: both P = .01), Multiracial enrolled students and graduates (overall: both P < .05, master’s level: both P < .05), and Asian tenured professors (P = .01). Significant decreases were observed among Unknown enrolled students (overall: P = .01, master’s level: P < .001), Unknown master’s level graduates (P = .01), AI/AN enrolled students (overall and master’s: both P < .05), and White full professors (P < .001) and tenured faculty (P < .001). Despite these findings, no substantial change existed among the other racial and ethnic groups. More efforts are needed to recruit, train, and promote racial and ethnic minorities who can leverage their lived experiences to provide novel solutions to environmental challenges.

The global pandemic of COVID-19 has highlighted the importance of understanding the role that exhaled droplets play in virus transmission in community settings. Computational Fluid Dynamics (CFD) enables systematic examination of roles the exhaled droplets play in the spread of SARS-CoV-2 in indoor environments. This analysis uses published exhaled droplet size distributions combined with terminal aerosol droplet size based on measured peak concentrations for SARS-CoV-2 RNA in aerosols to simulate exhaled droplet dispersion, evaporation, and deposition in a supermarket checkout area and rideshare car where close proximity with other individuals is common. Using air inlet velocity of 2 m/s in the passenger car and ASHRAE recommendations for ventilation and comfort in the supermarket, simulations demonstrate that exhaled droplets <20 µm that contain the majority of viral RNA evaporated leaving residual droplet nuclei that remain aerosolized in the air. Subsequently ~ 70% of these droplet nuclei deposited in the supermarket and the car with the reminder vented from the space. The maximum surface deposition of droplet nuclei/m² for speaking and coughing were 2 and 819, 18 and 1387 for supermarket and car respectively. Approximately 15% of the total exhaled droplets (aerodynamic diameters 20-700 µm) were deposited on surfaces in close proximity to the individual. Due to the non-linear distribution of viral RNA across droplet sizes, however, these larger exhaled droplets that deposit on surfaces have low viral content. Maximum surface deposition of viral RNA was 70 and 1.7 × 10³ virions/m² for speaking and 2.3 × 10⁴ and 9.3 × 10⁴ virions/m² for coughing in the supermarket and car respectively while the initial airborne concentration of viral RNA was 7 × 10⁶ copies per ml. Integrating the droplet size distributions with viral load distributions, this study helps explain the apparent importance of inhalation exposures compared to surface contact observed in the pandemic.

BACKGROUND: For centuries malaria infection remains a public health burden globally as well as in the Sunyani Municipality. This exploratory qualitative study aimed to assess the prospects of environmental management and sanitation (EMS) as a malaria vector control strategy among key stakeholders involved in the prevention and control of malaria in Sunyani Municipality, Ghana.

METHOD: We used an exploratory qualitative study and a designed focus group discussion (FGD) guide (with specific research questions) to solicit opinions and/or views among Malaria Control Focal Persons, Environmental Health Officers (Health Inspectors), and Honourable Assembly Members. Data were collected between December 2019 and February 2020. The responses were analyzed according to the specific research questions.

RESULT: Findings from this study shows that high government support and/or political will by investing in environmental sanitation infrastructure, creating the enabling environment for strict enforcement of environmental sanitation bye-laws by Environmental Health Officers/Health Inspectors, effective and efficient collaboration among key stakeholders and organization of communal labor activities is likely to help reduce the majority of the mosquito breeding sites.

CONCLUSION: The prospects of environmental management and sanitation (EMS) as a vector control strategy, look promisingly very high, pertinent, and workable and a likelihood game changer of winning the fight against malaria due to the residual transmission that is happening outdoors. However, EMS can be employed as a supplementary method to the current core vector control methods if the following conditions and bottlenecks are addressed and in place: (a) Effective collaboration among key stakeholders at all levels; (b) Adequate allocation of funds to the Environmental Health and Sanitation Department; (c) Enactment of robust educational campaigns across all educational levels and via different media; (d) Recognition, empowerment, and adequate resourcing of Environmental Health Officers; (e) Adherence to the building regulations to prevent encroachment of natural wetlands; (f) Revision of fees/fines and prosecution of sanitary offenders; (g) Enactment of an Environmental Sanitation Day (ESD), and establishment of the Environmental Health and Sanitation Fund (EHSF).

AIMS AND OBJECTIVES: This study investigated occupational exposure to blood and body fluids among nurses at the emergency department and intensive care units of public hospitals in Addis Ababa city.

METHODS: A cross-sectional study was conducted from June 18, 2021 to September 20, 2021. A simple random sampling method and semi-structured, self-administered questionnaires were used to collect the data, which were analyzed using SPSS version 25. A binary logistic regression model was used to identify factors associated with exposure to blood and body fluids on the AOR with a 95% confidence interval at a P-value of <.05.

PATIENT AND PUBLIC INVOLVEMENT: No patients were involved in this study.

RESULTS: Of the total study participants (260), 198 (76%) nurses had been exposed to blood and body fluids in their professional live, and 167 (64%) were exposed to blood and body fluids in the last 12 months. Being male (AOR = 2.88, 95% CI: (1.35, 6.12), lacking access to handwashing facilities (AOR = 5.02, 95% CI: (3.73, 14.51)), not consistently wearing all the required types of personal protective equipment (AOR = 6.21, 95% CI: (2.39, 9.55)), and the lack of the required personal protective equipment (AOR = 5.53, 95% CI: (1.87, 10.38)) were all significant factors that were positively associated with exposure to blood and body fluids.

CONCLUSION: This study showed that a higher proportion of nurses in the emergency department and intensive care unit were exposed to blood and body fluids in the study setting. Most nurses do not consistently wear all the required types of personal protective equipment, putting them at a higher risk of acquiring blood-borne pathogens. The authors recommended that there is a need to implement and strengthen appropriate and consistent use of all required personal protective equipment during any procedure, and patient care to reduce exposure to blood and body fluids.

RELEVANCE TO CLINICAL PRACTICE: This study provides baseline information for other action-based studies to assess exposure to blood and body fluids among nurses in emergency and intensive care units.

STROBE CHECKLIST: This manuscript was prepared based on the strobe checklist guidelines.

IMPACT STATEMENT: The study’s findings and recommendations might be used for healthcare providers, non-governmental organizations, and policymakers for appropriate planning and interventions to minimize or safeguard nurses’ exposure to blood and body fluids.

Indigenous Peoples and their deep knowledges offer a fundamentally important way of seeing the world and the environment. Through relationships to distinct ancestral homelands, Indigenous Peoples have developed unique ways of surviving, adapting, connecting, and relating to their respective environments. Indigenous Sacred Places themselves are connections to ancestors, to all beings on the planet, and to different planes of existence. Sacred Places serve an important environmental role in many Indigenous Nations around the globe. Yet, Indigenous Sacred Places, and in particular understandings of spirit that connect Sacred Places, have been historically and contemporarily marginalized and excluded from environmental health academic discourse and spaces. This despite concrete calls for the amplification of Indigenous traditional knowledges—that of which does not separate spirit from knowledge, or spirit from action—they are intertwined. With this, we sought to amplify in this Perspective, understandings and connectivity between Sacred Places, spirit, and environmental health through the stories from Indigenous Elders, processes of ceremony, and personal synthesis.

Harmattan is a season of dry, cold, dusty wind, and haze that is peculiar to West Africa. This season and COVID-19 share common conditions such as malaise and respiratory issues like as runny nose, cough and sneezing, and raise a question of a possible relationship that begs to be answered. This study investigated whether the meteorological factors of humidity and wind speed during harmattan have association with COVID-19 incidence and mortality in the 2 major COVID-19 epicenters of Lagos state and the Federal Capital Territory (FCT) in southern and northern geopolitical regions of Nigeria respectively. Data used were from March, 2020 to February, 2022, which corresponded to the period of 2 years after the first case of COVID-19 was detected in Nigeria. Correlation analysis was performed using incidence or mortality data on COVID-19 over the duration of 2 years and during the harmattan periods, as well as the humidity and wind speed data for the corresponding periods. Our results showed that there was no significant correlation between the humidity or wind speed and COVID-19 daily incidence or mortality during the harmattan and non-harmattan periods in Lagos state. In the FCT however, there was a significant positive correlation between humidity and COVID-19 incidence, as well as a negative correlation between wind speed and COVID-19 incidence. No significant correlation existed between humidity or wind speed and daily mortality. Taken together, the findings of this study show that weather components of the harmattan season have association with COVID-19 incidence but not mortality, and the association could vary depending on location.

BACKGROUND: Provision of handwashing facilities and proper practices are essential for preventing fecal-oral and acute respiratory infectious diseases. The aim of this study was to assess availability of handwashing facilities and predictors to students’ good hygiene practices in Addis Ababa, Ethiopia.

METHODS: A mixed-methods study design was conducted in schools of Addis Ababa from January to March 2020 in 384 students, 98 school directors, 6 health clubs, and 6 school administrators. Data were collected using pretested interviewer-administered questionnaires, interview guide, and observational checklists. The quantitative data were entered into EPI Info version 7.2.2.6 and analyzed using SPSS 22.0. A bivariable at P < .2 and multivariable logistic regression analysis at P < .05 for quantitative and thematic analysis for qualitative data were used.

RESULTS: Handwashing stations were available in 85 (86.7%) of the schools. However, 16 (16.3%) schools had neither water nor soap near the handwashing facilities while 33 (38.8%) of schools had both. There was no high school that had both soap and water. Approximately one-third (135, 35.2%) of students practiced proper handwashing, among which 89 (65.9%) were from private schools. The handwashing practices were significantly associated with gender (AOR = 2.45, 95% CI: (1.66-3.59)), having trained coordinator (AOR = 2.16, 95% CI: (1.32-2.48)) and health education program (AOR = 2.53, 95% CI: (1.73-3.59)), school ownership (AOR = 0.49, 95% CI: (0.33-0.72)), and training (AOR = 1.74, 95% CI: (1.82-3.69)). Water supply interruption, and lack of budget, adequate space, training, health education, maintenance, and coordination were the main barriers that prevent students from practicing proper handwashing.

CONCLUSIONS: Handwashing facilities and materials provision and good handwashing practices of students were low. Moreover, providing soap and water for handwashing was insufficient to promote good hygiene practices. There should be regular hygiene education, training, maintenance, and better coordination among stakeholders to create a healthy school environment.
