Occupational groups and lower urinary tract symptoms: A cross-sectional analysis of women in the Boston Area Community Health Study.

OBJECTIVES: The objective of this study is to inform our hypothesis that the workplace toileting environment may impact lower urinary tract symptoms (LUTS); we examined the prevalence of LUTS across occupational groups in the Boston Area Community Health Survey. METHODS: At baseline, women (n = 3205) reported their occupation and frequency of 15 LUTS. Using the US Department of Labor's Standard Occupational Classification (SOC) system, we categorized women into 11 standard occupational groups. Prevalence ratios (PRs) were calculated by log-link generalized linear models, adjusting for age, race, education, fluid intake, and parity. Women classified in Office and Administrative Support were used as the reference group given their potential for fewer workplace toileting restrictions. RESULTS: Of the 3189 women with complete data, 68% of women reported any LUTS, ranging from 57% to 82% across the SOCs. Relative to women in Office and Administrative Support (n = 576), women in Computing, Engineering, and Science (n = 64) were more likely to report any LUTS (PR = 1.2, 95% confidence interval [95% CI]: 1.0-1.4) and urinating again in <2 h (PR = 1.7, 95% CI: 1.4-2.2), and women in Education, Legal, Community Service, Arts, and Media (n = 477), as well as Healthcare Practitioner and Technical Occupations (n = 162), were less likely to report perceived frequent daytime urination (PR = 0.6, 95% CI: 0.5-0.9 and PR = 0.6, 95% CI: 0.4-0.9, respectively). CONCLUSIONS: Our cross-sectional findings suggest that urination frequency varies across understudied occupational groups with various workplace toileting environments. Future studies should examine this relationship prospectively to inform the influence of workplace toileting environments on urination frequency, as well as the development and/or worsening of LUTS.

Determinants of malaria infections among children in refugee settlements in Uganda during 2018-2019.

BACKGROUND: While 5% of 247 million global malaria cases are reported in Uganda, it is also a top refugee hosting country in Africa, with over 1.36 million refugees. Despite malaria being an emerging challenge for humanitarian response in refugee settlements, little is known about its risk factors. This study aimed to investigate the risk factors for malaria infections among children under 5 years of age in refugee settlements in Uganda. METHODS: We utilized data from Uganda's Malaria Indicator Survey which was conducted between December 2018 and February 2019 at the peak of malaria season. In this national survey, household level information was obtained using standardized questionnaires and a total of 7787 children under 5 years of age were tested for malaria using mainly the rapid diagnostic test. We focused on 675 malaria tested children under five in refugee settlements located in Yumbe, Arua, Adjumani, Moyo, Lamwo, Kiryadongo, Kyegegwa, Kamwenge and Isingiro districts. The extracted variables included prevalence of malaria, demographic, social-economic and environmental information. Multivariable logistic regression was used to identify and define the malaria associated risk factors. RESULTS: Overall, malaria prevalence in all refugee settlements across the nine hosting districts was 36.6%. Malaria infections were higher in refugee settlements located in Isingiro (98.7%), Kyegegwa (58.6%) and Arua (57.4%) districts. Several risk factors were significantly associated with acquisition of malaria including fetching water from open water sources [adjusted odds ratio (aOR) = 1.22, 95% CI: 0.08-0.59, P = 0.002], boreholes (aOR = 2.11, 95% CI: 0.91-4.89, P = 0.018) and water tanks (aOR = 4.47, 95% CI: 1.67-11.9, P = 0.002). Other factors included pit-latrines (aOR = 1.48, 95% CI: 1.03-2.13, P = 0.033), open defecation (aOR = 3.29, 95% CI: 1.54-7.05, P = 0.002), lack of insecticide treated bed nets (aOR = 1.15, 95% CI: 0.43-3.13, P = 0.003) and knowledge on the causes of malaria (aOR = 1.09, 95% CI: 0.79-1.51, P = 0.005). CONCLUSIONS: The persistence of the malaria infections were mainly due to open water sources, poor hygiene, and lack of preventive measures that enhanced mosquito survival and infection. Malaria elimination in refugee settlements requires an integrated control approach that combines environmental management with other complementary measures like insecticide treated bed nets, indoor residual spraying and awareness.

Can open-defecation free (ODF) communities be sustained? A cross-sectional study in rural Ghana.

Community-led total sanitation (CLTS) is a widely used approach to reduce open defecation in rural areas of low-income countries. Following CLTS programs, communities are designated as open defecation free (ODF) when household-level toilet coverage reaches the threshold specified by national guidelines (e.g., 80% in Ghana). However, because sanitation conditions are rarely monitored after communities are declared ODF, the ability of CLTS to generate lasting reductions in open defecation is poorly understood. In this study, we examined the extent to which levels of toilet ownership and use were sustained in 109 communities in rural Northern Ghana up to two and a half years after they had obtained ODF status. We found that the majority of communities (75%) did not meet Ghana's ODF requirements. Over a third of households had either never owned (16%) or no longer owned (24%) a functional toilet, and 25% reported practicing open defecation regularly. Toilet pit and superstructure collapse were the primary causes of reversion to open defecation. Multivariate regression analysis indicated that communities had higher toilet coverage when they were located further from major roads, were not located on rocky soil, reported having a system of fines to punish open defecation, and when less time had elapsed since ODF status achievement. Households were more likely to own a functional toilet if they were larger, wealthier, had a male household head who had not completed primary education, had no children under the age of five, and benefitted from the national Livelihood Empowerment Against Poverty (LEAP) program. Wealthier households were also more likely to use a toilet for defecation and to rebuild their toilet when it collapsed. Our findings suggest that interventions that address toilet collapse and the difficulty of rebuilding, particularly among the poorest and most vulnerable households, will improve the longevity of CLTS-driven sanitation improvements in rural Ghana.

Nontyphoidal Salmonella among Children under 5 Years Old in Sub-Saharan Africa and South Asia in the Global Enteric Multicenter Study.

Factors associated with nontyphoidal Salmonella (NTS) infection have not been well characterized to date. We aimed to compare the associated factors among children under age 5 years with NTS infection in sub-Saharan Africa and South Asia. Data from children having moderate-to-severe diarrhea (MSD) and asymptomatic children with NTS isolated from fecal specimens were extracted from the Global Enteric Multicenter Study (GEMS), conducted from December 2007 to March 2011. Compared with NTS-negative children, NTS-associated MSD cases in South Asia were associated with the presence of goat in the house (adjusted odds ratio [aOR]: 2.15; 95% confidence interval [CI]: 1.25-3.70) and handwashing after handling an animal (aOR: 2.26; 95% CI: 1.36-3.74). In sub-Saharan Africa, children with NTS associated MSD had a greater association with stunting (1.21 95% CI: 1.01-1.45), longer duration of diarrhea (aOR: 1.25 95% CI: 1.19-1.31); presence of cow in house (aOR: 1.54 95% CI: 1.09-2.16), handwashing after handling animal (aOR: 2.41 95% CI: 1.74-3.33). Drinking tube well water (aOR: 0.54 95% CI: 0.32-0.91), availability of toilet facility (aOR: 0.58 95% CI: 0.53-0.65), and handwashing before eating (aOR: 0.76 95% CI: 0.57-1.00) and after defecation (aOR: 0.80 95% CI: 0.69, 0.94) were found to be protective. The differentials between children of both regions having fecal NTS are distinct and underscore the need for policymaking for preventive and control strategies targeting stunted children.

Prevalence and associated factors of Tunga penetrans infestation among 5-14-year-olds in rural Ethiopia.

BACKGROUND: Tunga penetrans, also known as sand flea, causes Tungiasis in humans and animals. Despite its notoriety as an entomological problem, however, the ectoparasite receives little consideration from public health professionals. It is against this background that this article aims to assess the prevalence of and factors associated with Tunga penetrans infestation among 5-14-year-olds in rural Western Ethiopia. METHODS: From November to December 2020, 487 children aged 5 to 14 were selected from four primary schools in a cross-sectional study using systematic random sampling. Clinical exams, Interviews with parents/guardians and observations of the housing and classroom environments were used to collect data. Descriptive statistics and multivariable regression were used to characterize the data and identify factors associated with Tunga penetrans infestation. RESULT: Tunga penetrans infestation (Tungiasis) was diagnosed in 138 of the 487 children examined, placing the prevalence at 28.3% (95% CI: 24.2%, 32.2%). Mud plastered walls [AOR: 5.83, % CI (3.44-9.88)], having cats in the house [AOR: 5.91, 95% CI (3.51-10.11)], not having separated sleeping quarters for animals [AOR: 4.60, 95% CI (2.69-7.86)], using self-supplied water [AOR: 6.30, 95% CI (3.33-11.93)], walking>30 minutes to school [AOR: 2.37, 95% CI (1.48-3.80)] were associated with Tungiasis. CONCLUSION: In one way or another, several of the identified factors were linked to poverty. Improved house wall materials, fumigation of mud-plastered houses, dusting or spraying insecticides on domestic animals (such as cats), improved access to water, community education about keeping animals separated from living spaces, and hygiene promotion are all needed, with a focus on locally available, low-cost technologies that the poorest families can afford.

The Availability of Improved Sanitation Facilities and Its Associated Factors in the 12th District of Kandahar City, Afghanistan.

Background: The majority of people practicing open defecation and utilizing unhealthy sanitation facilities are in the developing world. The utilization of unimproved sanitation facilities remains the primary risk factor for many diseases, including nutritional diseases, diarrheal diseases, typhoid, cholera, and dysentery, particularly among children. Objectives: This study was carried out to assess the availability of improved sanitation facilities and factors associated with it in the 12th district of Kandahar city, Kandahar Province, Afghanistan. Methods: The study is a cross-sectional survey, conducted between September and October 2019. A structured questionnaire was used to gather self-reported information of the respondents, including sociodemographic information, household characteristics, and behavioral and environmental characteristics of the available sanitation facilities. Factors associated with the availability of the improved sanitation facility were determined using a multivariable logistic regression model. Results: In this study, the availability of improved sanitation facilities was 85.7% (95% confidence interval (CI) = 77.6%-92.1%). It was significantly influenced by living in a private house (adjusted odds ratio (AOR) = 2.99 (95% CI; 1.43-6.26)); inside location of latrine (AOR = 14.31 (95% CI; 3.59-56.99)); individual household latrine (AOR = 2.03 (1.04-3.95)); and the number of latrines in the household (AOR = 5.04 (2.45-10.35)). Conclusion: The availability of improved sanitation facilities was higher compared to the national level in the study area. This study provides significant evidence on approaches in line with the World Health Organization's (WHO) Joint Monitoring Program and Sustainable Developmental Goals (SDGs) for enhancing the availability of improved sanitation facilities in Kandahar city.

Having a latrine facility is not a guarantee for eliminating open defecation owing to socio-demographic and environmental factors: The case of Machakel district in Ethiopia.

BACKGROUND: Open defecation practice problem is rampant in most rural areas of developing countries, including Ethiopia. To combat this problem, the Ethiopian government implemented different sanitation interventions including Community-Led Total Sanitation and Hygiene (CLTSH). The CLTSH approach is mainly aimed to eradicate open defecation practice through mobilizing the community to construct a latrine facility and utilize it. Although this intervention has significantly improved households' access to a latrine facility, its impact on bringing behavioral change such as avoiding open defecation is not well studied. OBJECTIVE: Our study aimed to assess the prevalence of open defecation among households having their latrine and its determinant factors in rural settings in Northwest Ethiopia. METHODS: A community-based cross-sectional study was conducted in Machakal district from September 1 to 30, 2019. A total of 472 household heads who had a latrine facility and systematically selected from six rural Kebeles of the district, were involved in the study. The data were collected using a structured questionnaire and observational checklist tools through face-to-face interviews and observation methods. Bivariate and multivariable logistic regression models were run to identify the factors that influence open defecation practice. During the multivariable analysis, statistical significance was declared at the p-value of <0.05 with 95% CI. RESULTS: The prevalence of open defecation practice among household heads who had latrine facility was 27.8% (95% CI, [23.1-32.8]). Female gender (AOR = 2.94, 95% CI [1.13-7.68]), not attending of formal education (AOR = 3.10, CI 95% [1.34-7.13]), having >5 family members (AOR = 1.72, CI 95% [1.05-2.80]), presence of under-five child (AOR = 3.64 CI 95% [2.14-6.21]), preferring leaf as anal cleaning material (AOR = 3.18, CI 95% [1.67-6.08]), having unclean latrine (AOR = 2.15, CI 95% [1.34-3.44]), and having latrine that needs maintenance (AOR = 2.50 CI 95% [1.52-4.11]) variables were associated with open defecation practice. CONCLUSIONS: Among the total respondents, finding more than a quarter of open defecators is concerning for a district that achieved greatly in terms of latrine coverage. This indicates the above-mentioned factors contributed to influence household heads to defecate openly despite having latrines. Therefore, the government and partners need to focus on designing strategies that effectively address determinant factors of open defecation.

Detection of SARS-CoV-2 RNA on contact surfaces within shared sanitation facilities.

Contamination of contact surfaces with SARS-CoV-2 has been reported as a potential route for the transmission of COVID-19. This could be a major issue in developing countries where access to basic sanitation is poor, leading to the sharing of toilet facilities. In this study, we report SARS-CoV-2 contamination of key contact surfaces in shared toilets and the probabilistic risks of COVID-19 infections based on detection and quantification of the nucleic acid on the surfaces. We observed that 54-69% of the contact surfaces were contaminated, with SARS-CoV-2 loads ranging from 28.1 to 132.7 gene copies per cm2. Toilet seats had the highest contamination, which could be attributed to shedding of the virus in feces and urine. We observed a significant reduction in viral loads on the contaminated surfaces after cleaning, showing the potential of effective cleaning on the reduction of contamination. The pattern of contamination indicates that the most contaminated surfaces are those that are either commonly touched by users of the shared toilets or easily contaminated with feces and urine. These surfaces were the toilet seats, cistern handles and tap handles. The likelihood (probability) of infection with COVID-19 on these surfaces was highest on the toilet seat (1.76 × 10-4(1.58 × 10-6)) for one time use of the toilet. These findings highlight the potential risks for COVID-19 infections in the event that intact infectious viral particles are deposited on these contact surfaces. Therefore, this study shows that shared toilet facilities in densely populated areas could lead to an increase in risks of COVID-19 infections. This calls for the implementation of risk reduction measures, such as regular washing of hands with soap, strict adherence to wearing face masks, and effective and regular cleaning of shared facilities.

Unhygienic stool-disposal practices among mothers of children under five in Cambodia: Evidence from a demographic and health survey.

BACKGROUND: Unhygienic disposal of children's stools affects children's health in terms of their susceptibility to many diseases. However, there are no existing studies into the impact of unhygienic stool disposal in Cambodia. Therefore, this study aimed to identify factors associated with the unhygienic disposal of children's stools among children under the age of five in Cambodia. METHODS: An analytical cross-sectional study was conducted using data from the Cambodia Demographic and Health Survey (CDHS) 2014. A multivariable binary logistic regression was conducted using Stata to analyze factors associated with the unhygienic disposal of children's stools. RESULTS: Overall, the prevalence of practicing unhygienic disposal of children's stools was 29.27% (95%CI: 27.51%- 31.09%). Factors statistically associated with this practice were: living in the Central Plain, Plateau and Mountains, Coastal and Sea regions (AOR = 1.65; 95% CI: 1.33-2.04), (AOR = 2.53; 95% CI: 1.98-3.24) and (AOR = 4.16; 95% CI: 3.15-5.48) respectively, poor household wealth (AOR = 1.58; 95% CI: 1.31-1.91), the mother having no education (AOR = 1.45; 95% CI: 1.14-1.85), a high number of children aged under five (AOR = 1.11; 95% CI: 1.03-1.20), being in the "other" religious category (AOR = 1.77; 95% CI: 1.25-2.51), living in a household with unimproved toilet facilities (AOR = 1.22; 95% CI: 1.11-1.34), living in a household with inadequate hygiene (AOR = 1.33; 95% CI: 1.12-1.59), and the household not being visited by a family planning worker in the last year (AOR = 1.45; 95% CI: 1.19-1.77). However, an increase in the child's age by even a month had significant negative associations with unhygienic practice (AOR = 0.65; 95% CI: 0.60-0.70), even when controlling for other covariates. CONCLUSION: Almost one third of the mothers do not practice hygienic disposal of children's stools in Cambodia. Unhygienic practices were more prevalent in certain regions, and were also associated with low wealth, lack of education, an increase in the number of children under five in the household, religion, lack of sanitation and access to healthcare professionals. Conversely, the child's age was found to be positively associated with the hygienic disposal of children's stools.

Predictors of intestinal parasite infection among HIV patients on antiretroviral therapy in Jos, Plateau State, Nigeria, 2016: a cross-sectional survey.

INTRODUCTION: intestinal parasitic infection has been reported as a cause of morbidity and mortality among HIV patients on antiretroviral therapy (ART) due to interruption in treatment of the defaulting HIV patients. This study aimed to determine the prevalence and possible causes of intestinal parasites among HIV patients on ART. METHODS: a survey involving 375 adult HIV/AIDS patients selected using a systematic random sampling technique was conducted in a Jos University Teaching hospital, Plateau State, Nigeria. Socio-demographic and clinical data was collected using semi-structured interviewer administered questionnaire and electronic dataset review. Fresh stool samples were collected from all participants for laboratory identification of intestinal parasites using formol-ether sedimentation and modified Ziehl-Neelsen techniques. Descriptive statistics, odds ratio and logistic regression model were computed at P ≤ 0.05. RESULTS: the mean age of the study participants was 41.6±9.3years. Majority 294 (78.4%) were females, 141 (37.6%) lived in the rural area, 50 (13.3%) respondents did not have toilets in their homes. Most 275 (73.3%) had ART adherence level of 95% and above. Prevalence of intestinal parasites was 28.5%. Females (aOR = 2.14, 95% CI=1.12 - 3.89) and participants with no toilet facilities (aOR = 2.0, 95% CI=1.03 - 3.94) were significantly more likely to have intestinal parasites. CONCLUSION: the prevalence of intestinal parasites was high among HIV patients. Gender and unavailability of toilet in homes were found to be predictors of having parasites. We recommend that HIV patients should be periodically screened for IPs during the follow-up clinic visits.

Effect of a Community-led Total Sanitation Intervention on the Incidence and Prevalence of Diarrhea in Children in Rural Ethiopia: A Cluster-randomized Controlled Trial.

We conducted a cluster-randomized trial in 48 rural villages of Ethiopia to assess the effect of community-led total sanitation (CLTS) on the diarrhea incidence of children. Twenty-four villages were randomly assigned to the intervention group and the other 24 were assigned to the control group. A CLTS intervention was implemented from January 2016 through January 2017. Baseline data collection was conducted during October and November 2015. At baseline, 906 children were recruited and followed-up until January 2017. These 906 children were randomly selected among all children in the 48 villages. To determine the 7-day period prevalence of diarrhea, four household-based surveys were conducted by independent data collectors at 3, 5, 9, and 10 months after the CLTS was initiated. To determine the incidence and longitudinal prevalence, the presence of daily diarrhea presence was recorded for 140 days using diary methods. The loss to follow-up rates were 95% for period prevalence and 93% for incidence and longitudinal prevalence. The incidence ratio and longitudinal prevalence ratio were 0.66 (95% confidence interval [CI], 0.45-0.97; P = 0.03) and 0.70 (95% CI, 0.52-0.95; P = 0.02) after adjusting for clustering and stratification. The relative risk of period prevalence was 0.66 (95% CI, 0.45-0.98; P = 0.04) at 3 months after initiation. Improved toilet coverage increased from 0.0% at baseline to 35.0% at 10 months in the intervention villages, whereas it increased from 0.7% to 2.8% in the control villages. Adherence to the intervention was comparable with that of previous studies; therefore, we suggest that the findings of this study are replicable.

Conceptual Behaviour Underpinning the Occurrence of Nonfaecal Matter in Faecal Sludge in Some Urban Communities, Ghana.

Faecal sludge (FS) management is pertinent to the achievement of sustainable development goal 6.2 around the world; yet it is constrained by urbanisation challenges, waste management complexities, and defective attitudes. These deny communities of the plausible supply of resources from FS. This paper assesses the perception underpinning the occurrence of nonfaecal matter in FS in Ghana. Primary data were obtained from 400 respondents in four communities in Brong Ahafo and Greater Accra Regions of Ghana, using a structured questionnaire. Data were analysed by using STATA software version 15. Chi-square test and multiple logistic regression were conducted on all independent variables and statistical significance was accepted at p < 0.05. The study identified the following as the most perceived frequently disposed nonfaecal matter into FS: sanitary pads and diapers (38.5%), fabrics/rags (23.2%), toilet rolls (20.8%), razor/shaving sticks (10.3%), and others (7.2%). Gender, state of toilet facility (roof or unroofed), presence of container for collecting other types of waste in the toilet room, and state of container in toilet room either covered or uncovered were the factors found to be significantly associated with the disposal of solid waste (SW) into FS at 95% confidence level. The fear of exposing used sanitary materials for rituals, the use of fabric as an alternative to toilet rolls, and the desire to conceal aborted pregnancies from the public were some of the reasons alluded to the disposal acts. Education and awareness campaigns on proper SW disposal practices, appropriate use of toilet facilities, and the resource potentials of FS were found to be the best way forward to discourage indiscriminate disposal of SW into FS.

Universal WASH coverage; what it takes for fragile states. Case of Jariban district in Somalia.

The paper assessed access to WASH service in the Jariban district of Somalia. One hundred and sixty-seven households were sampled to administer a questionnaire. Central tendency and logistical regression were used to analyse the data in SPSS 26. The findings show that access to safe drinking water sources is 57.5%. Of the 42.5% of respondents who did not access safe drinking water source, only 10.8% confirmed that they treat drinking water at the point of use. The main reason for household water treatment was the positive mindset (.272) of the household head towards water treatment. The majority (80.2%) of the respondents access approximately 13 litres per person per day. Woman-headed households were more likely to treat water before drinking than male-headed households. Only 26.9% of the respondents accessed basic sanitation. Of the respondents, 55.7% did not share latrines, while 44.3% share resulting in open defecation. WASH access in the study area remains low, resulting in health-related risks, including diarrhoeal disease. The limitation is that the paper only focused on access to WASH facilities in fragile contexts. A cross-sectional analysis of biological, physical and chemical properties of water at the source and point of use is recommended for further research.

Effectiveness of community and school-based sanitation interventions in improving latrine coverage: a systematic review and meta-analysis of randomized controlled interventions.

INTRODUCTION: Approximately 1000 children die each year due to preventable water and sanitation-related diarrheal diseases. Six in 10 people lacked access to safely managed sanitation facilities in 2015. Numerous community- and school-based approaches have been implemented to eradicate open defecation practices, promote latrine ownership, improve situation sanitation, and reduce waterborne disease. OBJECTIVE: Given that current evidence for sanitation interventions seem promising, the aim of this study was to systematically summarize existing research on the effectiveness of community- and school-based randomized controlled sanitation intervention in improving (1) free open defecation (safe feces disposal), (2) latrine usage, (3) latrine coverage or access, and (4) improved latrine coverage or access. METHODS: Eight electronic databases were searched: PubMed, Scopus, WHO Global Health Library (GHL), Virtual Health Library (VHL), POPLINE, Web of Science, Cochrane, and Google Scholar up to 26 April 2019. Original randomized clinical trials addressing community-based or school-based intervention that reported feces disposal and latrine coverage were deemed eligible. More than two researchers independently contributed to screening of papers, data extraction, and bias assessment. We conducted a meta-analysis by random-effects model. The risk of bias was assessed by the Cochrane risk of bias tool. RESULTS: Eighteen papers that matched all criteria and 16 studies were included in the final meta-analysis. Compared to the control, the sanitation intervention significantly increased safe feces disposal (OR 2.19, 95% CI 1.51-3.19, p < 0.05, I2 = 97.28), latrine usage (OR 3.72, 95% CI 1.71-8.11, p < 0.05, I2 = 91.52), latrine coverage or access (OR 3.95, 95% CI 2.08-7.50, p < 0.05, I2 = 99.07), and improved latrine coverage or access (OR 3.68, 95% CI 1.52-8.91, p < 0.05, I2 = 99.11). A combination of education and latrine construction was more effective compared to educational intervention alone. CONCLUSION: Our study showed strong evidence for both community- and school-based sanitation interventions as effective for the safe disposal of human excreta. The finding suggests major implications for health policy and design of future intervention in developing countries.

Achieving equitable uptake of handwashing and sanitation by addressing both supply and demand-based constraints: findings from a randomized controlled trial in rural Bangladesh.

BACKGROUND: Supply driven programs that are not closely connected to community demand and demand-driven programs that fail to ensure supply both risk worsening inequity. Understanding patterns of uptake of behaviors among the poorest under ideal experimental conditions, such as those of an efficacy trial, can help identify strategies that could be strengthened in routine programmatic conditions for more equitable uptake. WASH Benefits Bangladesh was a randomized controlled efficacy trial that provided free-of cost WASH hardware along with behavior change promotion. The current paper aimed to determine the impact of the removal of supply and demand constraints on the uptake of handwashing and sanitation behaviors across wealth and education levels. METHODS: The current analysis selected 4 indicators from the WASH Benefits trial- presence of water and soap in household handwashing stations, observed mother's hand cleanliness, observed visible feces on latrine slab or floor and reported last child defecation in potty or toilet. A baseline assessment was conducted immediately after enrolment and endline assessment was conducted approximately 2 years later. We compared change in uptake of these indicators including wealth quintiles (Q) between intervention and control groups from baseline to endline. RESULTS: For hand cleanliness, the poorest mothers improved more [Q1 difference in difference, DID: 16% (7, 25%)] than the wealthiest mothers [Q5 DID: 7% (- 4, 17%)]. The poorest households had largest improvements for observed presence of water and soap in handwashing station [Q1 DID: 82% (75, 90%)] compared to the wealthiest households [Q5 DID: 39% (30, 50%)]. Similarly, poorer household demonstrated greater reductions in visible feces on latrine slab or floor [Q1DID, - 25% (- 35, - 15) Q2: - 34% (- 44, - 23%)] than the wealthiest household [Q5 DID: - 1% (- 11, 8%). For reported last child defecation in potty or toilet, the poorest mothers showed greater improvement [Q1-4 DID: 50-54% (44, 60%)] than the wealthier mothers [Q5 DID: 39% (31, 46%). CONCLUSION: By simultaneously addressing supply and demand-constraints among the poorest, we observed substantial overall improvements in equity. Within scaled-up programs, a separate targeted strategy that relaxes constraints for the poorest can improve the equity of a program.

Blowing in the wind: Bacteria and fungi are spreading from public restroom hand dryers.

This study aimed to identify and quantify fungi and bacteria in the airflow of restroom hand dryers in public areas. Airflow from restroom hand dryers in 8 retail locations was tested using three types of culture media, followed by PCR and sequence analysis to identify microbial species. Both bacterial and fungal colonies were detected in all locations. The number of colonies did not vary significantly across different locations, suggesting a similar level of microbial spread by hand dryers between different types of commercial stores. Molecular analysis revealed 24 bacterial species and 40 fungal species. Of these species, 48% (31/64) have been reported to be implicated in various infections in humans, primarily those with underlying medical conditions. This study is the first to demonstrate the spread of fungi by the airflow of restroom hand dryers, and the first to show the prevalence of different fungal and bacterial species spread by restroom hand dryers in common public areas.

Effectiveness of community and school-based sanitation interventions in improving latrine coverage: a systematic review and meta-analysis of randomized controlled interventions

INTRODUCTION@#Approximately 1000 children die each year due to preventable water and sanitation-related diarrheal diseases. Six in 10 people lacked access to safely managed sanitation facilities in 2015. Numerous community- and school-based approaches have been implemented to eradicate open defecation practices, promote latrine ownership, improve situation sanitation, and reduce waterborne disease.@*OBJECTIVE@#Given that current evidence for sanitation interventions seem promising, the aim of this study was to systematically summarize existing research on the effectiveness of community- and school-based randomized controlled sanitation intervention in improving (1) free open defecation (safe feces disposal), (2) latrine usage, (3) latrine coverage or access, and (4) improved latrine coverage or access.@*METHODS@#Eight electronic databases were searched: PubMed, Scopus, WHO Global Health Library (GHL), Virtual Health Library (VHL), POPLINE, Web of Science, Cochrane, and Google Scholar up to 26 April 2019. Original randomized clinical trials addressing community-based or school-based intervention that reported feces disposal and latrine coverage were deemed eligible. More than two researchers independently contributed to screening of papers, data extraction, and bias assessment. We conducted a meta-analysis by random-effects model. The risk of bias was assessed by the Cochrane risk of bias tool.@*RESULTS@#Eighteen papers that matched all criteria and 16 studies were included in the final meta-analysis. Compared to the control, the sanitation intervention significantly increased safe feces disposal (OR 2.19, 95% CI 1.51-3.19, p < 0.05, I@*CONCLUSION@#Our study showed strong evidence for both community- and school-based sanitation interventions as effective for the safe disposal of human excreta. The finding suggests major implications for health policy and design of future intervention in developing countries.

Knowledge, practices and seroprevalence of Taenia species in smallholder farms in Gauteng, South Africa.

Porcine cysticercosis and associated human infections are endemic in Sub-Saharan Africa, Latin America, and Asia. Poor agricultural practices, sanitary practices, and lack of knowledge increase the burden of the diseases in susceptible populations. This study investigates the seroprevalence of Taenia spp. in township pigs in Gauteng, South Africa and describes knowledge and farming practices of pig farmers regarding T. solium infections. Blood samples were collected from 126 pigs in three Gauteng township areas, and analyzed for active Taenia spp. infection using the B158/B60 Ag-ELISA. Farmer questionnaire surveys were conducted in four township areas to investigate the level of knowledge and practices associated with porcine cysticercosis and neurocysticercosis. Logistic regression models were used to assess the relationship between predictor variables and the outcome variable, knowledge of porcine cysticercosis or knowledge of neurocysticercosis. Overall, 7% of the pigs were seropositive for active Taenia spp. infection. 46% of farmers practiced a free-ranging system, while 25% practiced a semi-intensive system. Latrines were absent on all farms; however, 95% of farmers indicated that they have access to latrines at home. Most farmers had no knowledge of porcine cysticercosis (55%) or neurocysticercosis (79%), and this was not associated with any of the factors investigated. The prevalence of active Taenia spp. infection was reasonably low in this study, yet the knowledge level was also low, thus calling for further educational and training programmes to prevent Taenia spp. transmission in these communities.

Latrine Availability and Associated Factors among Religious Institutions in Northern Ethiopia, 2018.

Background: Religious institutions found in the community not only uphold belief and cultural values but can also act as a force for positive change and development. Improved sanitation and hygiene are crucial in these institutions to decrease preventable infections due to unsanitary conditions. However, there are no studies among religious institutions on availability of latrines. Therefore, this study was conducted to assess latrine availability and associated factors among religious institutions in the Tigray Region, Ethiopia. Method: An institution-based cross-sectional study design was conducted in the Tigray Region, Northern Ethiopia. Multistage sampling was used to sample 385 religious institutions. Data were collected using a pretested, structured questionnaire and observation checklist. Logistic regression was fitted, and an odds ratio with 95% confidence interval (CI) with p value less than 0.05 was used to determine the predictors of latrine availability. Analysis was carried out using the SPSS 20TM software package. Results: In this study, latrine availability was 32.8%. It was significantly affected by currently saved money towards having a latrine (adjusted odds ratio (AOR): 0.32, 95% confidence interval (CI) [0.25, 0.42]), any messages seen, heard, or received on sanitation and hygiene (AOR: 0.43, 95% CI [0.38, 0.51]), and the place where messages were seen, heard, or received (AOR: 2.95, 95% CI [1.11, 5.55]). Conclusion: Latrine availability was very low when compared to the national target of 100% among religious institutions and was affected by the currently saved money towards having a latrine, any messages seen, heard, or received on sanitation and hygiene, and the place where the messages were received. Information regarding latrine availability should be provided to the community visiting religious institutions through available channels and promotion of practical models.
