RESUMO
Achieving universal access to safely managed sanitation services is one of the Sustainable Development Goal 6 targets (SDG6.2). The cost and availability of services to ensure the safe management of on-site sanitation, such as pit latrines and septic tanks, can be major barriers for poor households. Particularly, fecal sludge emptying services have become increasingly important due to the growing urban population. This review aims to scope the literature on stated and revealed willingness to pay (WTP) for emptying on-site sanitation systems and to identify determinants of WTP and gaps in knowledge. We performed electronic searches of six databases. After deduplication, 1846 records were identified, of which 14 were included in the review. In these studies, we identified 26 distinct scenarios that reported mean or median WTP values for emptying services and their market price (i.e., price at which the services were provided). Among the 26 scenarios, 77% (n = 20) reported that WTP was lower than the market price. We identified 20 statistically significant determinants of WTP, which can be leveraged when developing or improving manual and mechanical emptying services to attract more customers. Future research should consider services that adopt flexible pricing or mobile money payment and optimize their emptying operations to increase WTP. Validating the effectiveness of such services in solving the WTP-market price imbalance is a significant knowledge gap.

Improved sanitation provides many benefits to human health and well-being and is integral to achieving Sustainable Development Goal Six. However, many nations, including most of sub-Saharan Africa, are not on track to meeting sanitation targets. Recognizing the inherent complexity of environmental health, we used systems thinking to study sanitation sustainability in Uganda. Our study participants, 37 sanitation actors in three rural districts, were engaged in interviews, group model building workshops, and a survey. The resulting model was parametrized and calibrated using publicly available data and data collected through the Uganda Sanitation for Health Activity. Our simulations revealed slippage from improved sanitation in all study districts, a behavior reflected in real interventions. This implies that systemic changes-changes to the rules and relationships in the system-may be required to improve sanitation outcomes in this context. Adding reinforcing feedback targeting households' perceived value of sanitation yielded promising simulation results. We conclude with the following general recommendations for those designing sanitation policies or interventions: (1) conceptualize sanitation systems in terms of reinforcing and balancing feedback, (2) consider using participatory and simulation modeling to build confidence in these conceptual models, and (3) design many experiments (e.g., simulation scenarios) to test and improve understanding.

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.

BACKGROUND: To examine the prevalence of toileting disability among older adults in India and its association with broad aspects of the physical and social environment. METHODS: We use data from the inaugural wave of the Longitudinal Ageing Study in India and focus on adults aged 65 and older (N = 20,789). We draw on the disablement process model and existing frameworks to identify environmental factors and other risk factors that may be associated with toileting disability. Hierarchical logistic regressions are implemented to analyze the health impacts from physical and social environment characteristics. RESULTS: One in five older Indian adults had difficulties with toileting, and the prevalence rate of this functional disability varied across sub-national regions. We find that low neighborhood trust was associated with an increased likelihood of toileting disability, as was the use of assistive mobility devices. The negative effects of these social and external environment characteristics hold when we stratified the sample by rural and urban residency. Also, older adults in urban areas without access to toilets and using shared latrines had higher odds of being disabled in terms of toileting. Other factors important in explaining toileting disability among older adults included poor self-rated health, arthritis, currently working, living in the East or West region, and having functional limitations. CONCLUSIONS: Poor person-environment fit can compromise older adults' ability to perform self-care tasks. Policymakers need to look beyond the physical environment (e.g., dedicating resources to construct toilet facilities) to adopt a more holistic, multi-faceted approach in their sanitation policies. Improving the safety of neighborhood surroundings in which shared latrines are located and the availability of accessible toilets that cater to those with mobility impairments can help improve independence in toileting among older adults.

INTRODUCTION: There has been extensive research conducted on open defecation in Ethiopia, but a notable gap persists in comprehensively understanding the spatial variation and predictors at the household level. This study utilizes data from the 2021 Performance Monitoring for Action Ethiopia (PMA-ET) to address this gap by identifying hotspots and predictors of open defecation. Employing geographically weighted regression analysis, it goes beyond traditional models to account for spatial heterogeneity, offering a nuanced understanding of geographical variations in open defecation prevalence and its determinants. This research pinpoints hotspot areas and significant predictors, aiding policymakers and practitioners in tailoring interventions effectively. It not only fills the knowledge gap in Ethiopia but also informs global sanitation initiatives. METHODS: The study comprised a total weighted sample of 24,747 household participants. ArcGIS version 10.7 and SaT Scan version 9.6 were used to handle mapping, hotspots, ordinary least squares, Bernoulli model analysis, and Spatial regression. Bernoulli-based model was used to analyze the purely spatial cluster detection of open defecation at the household level in Ethiopia. Ordinary Least Square (OLS) analysis and geographically weighted regression analysis were employed to assess the association between an open defecation and explanatory variables. RESULTS: The spatial distribution of open defecation at the household level exhibited clustering (global Moran's I index value of 4.540385, coupled with a p-value of less than 0.001), with significant hotspots identified in Amhara, Afar, Harari, and parts of Dire Dawa. Spatial analysis using Kuldorff's Scan identified six clusters, with four showing statistical significance (P-value < 0.05) in Amhara, Afar, Harari, Tigray, and southwest Ethiopia. In the geographically weighted regression model, being male [coefficient = 0.87, P-value < 0.05] and having no media exposure (not watching TV or listening to the radio) [coefficient = 0.47, P-value < 0.05] emerged as statistically significant predictors of household-level open defecation in Ethiopia. CONCLUSION: The study revealed that open defecation at the household level in Ethiopia varies across the regions, with significant hotspots identified in Amhara, Afar, Harari, and parts of Dire Dawa. Geographically weighted regression analysis highlights male participants lacking media exposure as substantial predictors of open defecation. Targeted interventions in Ethiopia should improve media exposure among males in hotspot regions, tailored sanitation programs, and region-specific awareness campaigns. Collaboration with local communities is crucial.

BACKGROUND: Menstrual hygiene management (MHM) is associated with the menstrual process in women and adolescent girls who face cultural and financial challenges in rural areas of many developing countries. As part of the pilot study, we assessed the sustainability and effectiveness of the approaches and lessons learned from the MHM project intervention in rural areas of Lilongwe, Malawi. METHODS: Rural primary schools (n = 4) were purposively selected where an MHM intervention was implemented in Lilongwe, Malawi. The study employed a mixed-method research design. Assessments and data collection were performed through surveys of learners, literature reviews, key informant interviews (KIIs) (n = 90), and 20 focus group discussions (FGDs). The study participants included boys and adolescent girls (n = 100, 11-19 years; grades 5-8), teachers, mother groups, and community leaders from the selected schools. RESULTS: All the schools had water sanitation and hygiene facilities and latrines (45% improved, 54% ventilated improved pit latrines - VIPs) that promoted menstrual hygiene for adolescent girls. However, two of the schools studied (50%, n = 4) did not have separate washrooms for changing sanitary materials. There was a slight increase in latrine coverage in Kabuthu zone communities (90% at baseline versus 93.4% at midterm). However, the coverage dropped to 85.7% at the final evaluation, which was attributed to too much rain received in the area that damaged most of the latrines. There was a significant reduction (p < 0.05) in the number of girls failing to attend classes due to menstruation (70% at baseline versus 14% at final evaluation). Furthermore, the project resulted in the majority of girls (94.4%) having access to school. There was a strong uptake and adoption of sanitary products (reusable pads and menstrual cups) among adolescent girls of all age groups. The study has demonstrated that the inclusion of key stakeholders such as health workers, parents, mother groups and community leaders promoted the uptake and sustainability of reusable pads and menstrual cups and MHM interventions and programs. CONCLUSION: The MHM project implementation improved adolescent girls' education in the area. The inclusion of boys and other key stakeholders in the health education talks addressed issues of stigma and discrimination. The study, therefore, calls for comprehensive training on MHM and hygiene education to remove discrimination and harmful cultural practices.

Sanitation infrastructure can fail during heavy rainfall and flooding, allowing the release of fecal waste - and the pathogens it carries - into spaces where people live, work, and play. However, there is a scarcity of reliable frameworks that can effectively assess the resilience of such infrastructure to extreme rainfall and flooding events. The purpose of this study was to develop and apply a novel framework for assessing and ranking the resilience of sanitation infrastructure in informal settlements. A framework for assessing sanitation infrastructure resilience was developed consisting of 19 indicators that were categorized into three domains: physical infrastructure design (8 indicators), operations and management (5 indicators), and environmental factors (6 indicators). The framework was applied to data from 200 shared sanitation facilities in Kibera, Kenya, collected through transect walks, field observations, surveys, and sanitary risk inspections. Results indicate that sanitation infrastructure type impacts resilience. Toilet facilities connected to a piped sewer (r = 1.345, 95% CI: 1.19-1.50) and toilets connected to a septic system (r = 1.014, 95% CI: 0.78-1.25) demonstrated higher levels of resilience compared to latrines (r = 0.663, 95% CI: 0.36-0.97) and hanging toilets (r = 0.014, 95% CI: 0.30-0.33) on a scale ranging from 0 to 4. The key determinants of sanitation infrastructure resilience were physical design, functionality, operational and maintenance routines, and environmental factors. This evidence provides valuable insights for developing standards and guidelines for the design and safe siting of new sanitation infrastructure and encourages investment in sewer and septic systems as superior options for resilient sanitation infrastructure. Additionally, our findings underscore the importance for implementers and communities to prioritize repairing damaged infrastructure, sealing potential discharge points into open drains, and emptying filled containment systems before the onset of the rainy season.

Selecting an appropriate sanitation option involves multiple stakeholders with often conflicting objectives. A multiple criteria decision analysis (MCDA) framework was developed to inform decision makers on selecting appropriate sanitation options for rural communities. Criteria established from literature were evaluated and weighted on-line by stakeholders. A performance matrix was developed by assigning weights to criteria and scoring alternatives. Selection of alternatives was based on a composite appropriateness index from a rank using the simple multi-attribute ranking technique. The framework was evaluated by verification, validation and sensitivity analysis. Five alternatives were evaluated on 14 decision criteria. The first preferred alternative was the urine diverting dry toilet (72.54) then the Blair ventilated improved pit latrine (67.10). The framework was commented as reasonable and robust. A simple and transparent MCDA framework was developed considering local conditions in a participatory manner to select appropriate alternatives for rural sanitation where a single option is encouraged.

Low-income tropical regions, such as Haiti, grapple with environmental issues stemming from inadequate sanitation infrastructure for fecal sludge management. This study scrutinizes on-site sanitation systems in these regions, evaluating their environmental impacts and pinpointing improvement opportunities. The focus is specifically on systems integrating excreta valorization through composting and/or anaerobic digestion. Each system encompasses toilet access, evacuation, and sludge treatment. A comparative life cycle assessment was undertaken, with the functional unit managing one ton of excreta in Haiti over a year. Six scenarios representing autonomous sanitation systems were devised by combining three toilet types (container-based toilets (CBTs), ventilated improved pit (VIP) latrines, and flush toilets (WC)) with two sludge treatment processes (composting and biomethanization). Biodigester-based systems exhibited 1.05 times higher sanitary impacts and 1.03 times higher ecosystem impacts than those with composters. Among toilet types, CBTs had the lowest impacts, followed by VIP latrines, with WCs having the highest impacts. On average, WC scenarios were 3.85 times more impactful than VIP latrines and 4.04 times more impactful than those with CBTs regarding human health impact. Critical variables identified include the use of toilet paper, wood shavings, greenhouse gas emissions, and construction materials.

AIMS: This study aimed to evaluate the ergonomic design of toilets and bathroom equipment for older adults using anthropometric measurements. DESIGN: This was a descriptive cross-sectional study. METHODS: Data were collected from 2,721 people aged ≥ 65 years in Turkey. Fourteen anthropometric measurements were evaluated. Body dimension characteristics were described using minimum, maximum, and arithmetic means and standard deviations and the 5th, 25th, 50th, 75th, and 95th percentiles. RESULTS: The measurements showed that companies generally do not design bathroom toilet equipment that is suitable for older adults. CONCLUSION: This study provides advice to designers and manufacturers on how to adapt their products to the bathroom according to users' body characteristics in order to increase person-environment fit for older people.

In modern society, people engage in social interactions and activities outside their own home. When in public settings people may need to eliminate bodily waste, so public toilets are required. Accessibility, availability and adaptability are essential principles for safe, private, and purposeful visits to public toilets. A diverse range of individuals use public toilets: various age profiles, all gender groups, vulnerable individuals and people with additional needs. Public toilets essentially need to be a place of privacy, safety and cleanliness to facilitate elimination of urine, evacuation of faeces, management of menstruation, and changing/disposing of continence wear products in a secure environment.

Despite the Philippines' progress in gender equality, contemporary evidence suggests that Filipinos continue to possess negative attitudes toward lesbian and gay individuals. Likewise, discrimination and violence toward bisexual, transgender, and queer Filipinos have been documented. Despite cases of sexual orientation and gender identity and expression (SOGIE) based discrimination, national-level anti-discrimination legislation remains unpassed in the Senate. This study explores the national discussions on the SOGIE Equality Bill triggered by a bathroom discrimination experienced by a Filipino transgender woman in 2019. Taking cues from Richardson's sexual citizenship framework, we investigate the diverse rights discourses among sectoral groups, such as local lesbian, gay, bisexual, transgender, queer, and other individuals of marginalized sexualities and genders (LGBTQ+) organizations and their allies, high-ranking Filipino politicians, and religious organizations. Analysis of local discourses showed that those supporting the SOGIE Equality Bill leverage identity-based rights discourses, while those opposed primarily navigate these debates using conduct-based rights discourses. Future policy and advocacy work must leverage the insights from these public proceedings to foster LGBTQ + solidarity in their campaigns for LGBTQ + rights in the country. Particularly, future work must (1) locate the middle ground between the LGBTQ + community and opposed legislators; (2) highlight essential values and common issues shared by all Filipinos; (3) surface how privilege can preclude and advance solidarity within the LGBTQ + community; (4) campaign for the passage of local anti-discrimination ordinances; (5) improve the SOGIE-related competencies of policy implementers; and (6) engage in research that explores public discourses and meanings assigned to sexual rights among Filipinos.

OBJECTIVES: Innovations to improve public sanitation facilities, especially in healthcare facilities (HCFs) in low-income countries, are limited. SaTo pans represent novel, largely untested, modifications to reduce odour and flies and improve acceptability of HCF sanitation facilities. We conducted a pilot project to evaluate acceptability, cleanliness, flies and odour within latrines in 37 HCFs in Kisumu, Kenya, randomised into intervention (SaTo pan modifications) and control arms by sub-county and HCF level. METHODS: At baseline (pre-intervention) and endline (>3 months after completion of SaTo pan installations in latrines in intervention HCFs), we surveyed users, cleaners and in-charges, observed odour and cleanliness, and assessed flies using fly tape. Unadjusted difference-in-difference analysis compared changes from baseline to endline in patient-reported acceptability and observed latrine conditions between intervention and control HCFs. A secondary assessment compared patient-reported acceptability following use of SaTo pan versus non-SaTo pan latrines within intervention HCFs. RESULTS: Patient-reported acceptability of latrines was higher following the intervention (baseline: 87%, endline: 96%, p = 0.05). However, patient-reported acceptability was also high in the control arm (79%, 86%, p = 0.34), and the between-arm difference-in-difference was not significant. Enumerator-observed odour declined in intervention latrines (32%-14%) compared with controls (36%-51%, difference-in-difference ratio: 0.32, 95% confidence interval: 0.12-0.84), but changes in flies, puddling of urine and visible faeces did not differ between arms. In the secondary assessment, fewer intervention than control latrines had patient-reported flies (0% vs. 26%) and odour (18% vs. 50%), and reported satisfaction was greater. Most cleaners reported dropholes and floors were easier to clean in intervention versus controls; limited challenges with water for flushing were reported. CONCLUSIONS: Our results suggest SaTo pans may be acceptable by cleaners and users and reduce odour in HCF sanitation facilities, though challenges exist and further evaluation with larger sample sizes is needed.

Poor sanitation causes 30% of diarrheal deaths globally, and much of the world has struggled to finance top-down interventions. Sanitation marketing is a demand-led approach that uses a mixture of social and commercial marketing methods and direct sales to households. However, little is known about its impacts on household decision making. This mixed-methods study uses data from eight focus groups and 86,666 household surveys from participants in a five-year sanitation marketing program in Uganda. Logistic regression models identified 10 variables predicting attainment of improved (limited or basic) sanitation and four variables predicting female involvement in decision making. Triggering session attendance increased chances of reaching improved sanitation by 15-28%, depending on who attended, and by 19% if the household found the session motivational. Although women were engaged in decision-making conversations, they were not viewed as primary decision makers, even in female-headed households. Women were more likely to become involved in decision making if they had attended triggering sessions with men (+70%) or engaged with sales promoters alone (+74%) or with men (+78%). For both outcomes, joint activity engagement was more effective than male or female engagement alone. This work highlights two sanitation marketing activities as pathways to improving latrine coverage and women's decision-making agency.

INTRODUCTION: The use of public bathrooms is a challenge for everyone, but especially for those who are affected by a bathroom-dependent condition. Being dependent on bathrooms is linked with different negative emotions. One of them is a clinically relevant emotion: shame associated with the chronic condition. MATERIALS AND METHODS: In a cross-sectional survey study (n = 193) of people who suffer a bathroom-dependent condition we asked about health conditions, well-being, and shame related to chronic condition outcomes. RESULTS: We show a link between negative public bathroom experiences, and diminished well-being and feelings of shame related to chronic illness. We found that this relationship between negative experiences with public bathrooms and shame is not specific to the different conditions. CONCLUSION: We conclude that the negative experiences which people with different gastrointestinal illnesses face is an environmental stressor associated with more embarrassment as a result of the condition suffered.

BACKGROUND: Across developing countries poor sanitation is associated with disease often found widespread in rural populations. OBJECTIVES: This objective of this study was to conduct a formative research and feasibility evaluation of the behavioural intervention designed to improve latrine use in rural India. METHODS: Study conducted in four villages of Rajasthan, where latrine use is low and open defecation may spread disease. To identify the intervention a literature review was conducted, a survey of 497 households, and focus groups in village households (8-10 women and children). Seven focus groups with 63 women were conducted. Based on the survey results, the behaviour change intervention is developed utilising the Capability-Opportunity-Motivation-behaviour model and MINDSPACE framework. One intervention component involves psychological aspects that engage villagers through a pledge; the other component is provision of small incentives to facilitate latrine use. Feasibility and acceptability of the intervention was examined in the study population. The 30-day intervention was delivered to women in 38 randomly selected households who despite having a functional latrine did not use it. Thematic analysis, binary logistic regression analysis and feasibility evaluation of the intervention conducted. Post-intervention feedback from 22 participating households was obtained. RESULTS: The piloted intervention was feasible and so a revised design is offered. Results driving this evaluation include barriers identified, and used to improved intervention design in the current study. Village authority figures influenced behaviours across the villages and so did factors of convenience (ß = 5.28, p < 0.01), relief (ß = 5.49, p < 0.01), comfort (ß = 2.36, p < 0.01), Construction cost (ß=-1.98, p < 0.01) and safety (ß = 2.93, p < 0.01) were significant concerns associated with latrine use in the context of prevalent OD in the region. The logistic regression baseline model for the dependant variables indicated a significant increase in latrine use. Based on the feasibility study, the intervention is refined in several ways. CONCLUSIONS: Our theory-driven approach improves latrine use in Rajasthan and offers a useful tool to facilitate hygiene behaviour.

BACKGROUND: Accessing household toilets is vital for adolescent health during crucial stages of growth and development; however, some ethnic minority families in China lack toilets. The relationship between household toilet accessibility and the physical health of adolescents in China's ethnic minority areas has been underexamined. METHODS: Using two waves of data from the China Education Panel Survey (2013 and 2014), this study explored the effect of household toilet accessibility on Chinese ethnic minority adolescents' physical health. The sample consisted of 576 ethnic minority adolescents with an average age of approximately 13 years. To test the health effect of household toilet accessibility on ethnic minority adolescents, a fixed effects ordinary least squares model and difference-in-differences combined with propensity score matching method were used. RESULTS: The results of the fixed effects model and difference-in-differences combined with propensity score matching showed a significant and positive effect of household toilet accessibility on adolescents' physical health. The heterogeneity analysis indicated that among the toilet types of soil cesspits, cement cesspits, squat toilets, and flush toilets, the flush toilets were proven to be the most efficient in improving adolescents' physical health. Moreover, the family living arrangement was proven to play a moderating role in the effect of household toilet accessibility on the physical health of ethnic minority adolescents. The average marginal effects of household toilet accessibility on the physical health of ethnic minority adolescents who lived without parents were more evident and significant than those who lived with their parents. CONCLUSION: Promoting household toilet accessibility in China's ethnic minority areas is essential for improving adolescents' health. Moreover, having a household toilet is not sufficient, the quality and dignity of household toilets are also important.

Few case studies exist in the public health or design literatures showing how to create national scale messaging campaigns in low-income countries using design processes. In this paper, we describe how we used Behaviour Centred Design to develop Nyumba ni choo, the Tanzanian National Sanitation Campaign. The process involved multiple iterations of ideation and filtration by professional creatives, government staff, academics and sanitation specialists to create a branded mass communication campaign, which was refreshed annually. The campaign was based on the insight that Tanzania is modernizing rapidly, with people upgrading their homes, but leaving their outside toilets in a 'traditional' state. Built around the 'big idea' that a household is not fully modern without a good-quality, modern toilet, the campaign employed reality TV shows, live engagements and mass and digital media postings, all targeted at motivating both the government and general population to improve toilets. The campaign has made toilets a topic of national conversation and has led to a major uptick in the rate of toilet building. Efforts to improve public health-related behaviour can be enhanced by using systematic approaches that build on available evidence, understand behaviour in its common settings, employ psychological theory and engage creative expertise.

Public toilets are a critical public health issue with a significant negative impact on people's lives. Unfortunately, the effect of negative experiences caused by public toilets on people's quality of life and life satisfaction is unknown. In this study, participants (n = 550) were asked to fill in a scale-based survey about their negative experiences with public toilets, quality of life, and life satisfaction. We found that people with toilet-dependent illnesses (36% of the sample) reported more negative experiences with public toilets than their counterparts. These negative experiences are also related to lower scores in some areas of participants' quality of life, such as their environmental, psychological, and physical health and life satisfaction, even after controlling for relevant socio-economic variables. Additionally, toilet-dependent individuals had particularly negative experiences in terms of life satisfaction and physical health than non-toilet-dependent people. We conclude that the impoverishment of quality of life linked to public toilets as an environmental inadequacy is traceable, estimable, and meaningful. This association is not only negative for ordinary people, but it is significantly negative for people with toilet-dependent illnesses. These results highlight that public toilets are essential to ensure collective well-being, particularly when considering those affected by their presence or lack thereof.

In low-income, urban, informal communities lacking sewerage and solid waste services, onsite sanitation (sludges, aqueous effluent) and child feces are potential sources of human fecal contamination in living environments. Working in informal communities of urban Maputo, Mozambique, we developed a quantitative, stochastic, mass-balance approach to evaluate plausible scenarios of localized contamination that could explain why the soil-transmitted helminth Ascaris remains endemic despite nearly universal coverage of latrines that sequester most fecal wastes. We used microscopy to enumerate presumptively viable Ascaris ova in feces, fecal sludges, and soils from compounds (i.e., household clusters) and then constructed a steady-state mass-balance model to evaluate possible contamination scenarios capable of explaining observed ova counts in soils. Observed Ascaris counts (mean = -0.01 log10 ova per wet gram of soil, sd = 0.71 log10) could be explained by deposits of 1.9 grams per day (10th percentile 0.04 grams, 90th percentile 84 grams) of child feces on average, rare fecal sludge contamination events that transport 17 kg every three years (10th percentile 1.0 kg, 90th percentile 260 kg), or a daily discharge of 2.7 kg aqueous effluent from an onsite system (10th percentile 0.09 kg, 90th percentile 82 kg). Results suggest that even limited intermittent flows of fecal wastes in this setting can result in a steady-state density of Ascaris ova in soils capable of sustaining transmission, given the high prevalence of Ascaris shedding by children (prevalence = 25%; mean = 3.7 log10 per wet gram, sd = 1.1 log10), the high Ascaris ova counts in fecal sludges (prevalence = 88%; mean = 1.8 log10 per wet gram, sd = 0.95 log10), and the extended persistence and viability of Ascaris ova in soils. Even near-universal coverage of onsite sanitation may allow for sustained transmission of Ascaris under these conditions.
