Household-level sanitation interventions have had limited effects on child health or environmental contamination, potentially due to low community coverage. Higher community-level coverage with safely managed can reduce opportunities for disease transmission.
Background Diarrhea and acute respiratory infection (ARI) are leading causes of death in children. The WASH Benefits Bangladesh trial implemented a multicomponent sanitation intervention that led to 39% reduction the prevalence diarrhea among children 25% for ARI, measured 1 2 years after implementation. We longer-term effects on these outcomes between 3.5 implementation, including periods with differing intensity behavioral promotion. Methods findings was cluster-randomized controlled...
Household latrine access generally is not associated with reduced fecal contamination in the environment, but its long-term effectiveness has been measured. We conducted an environmental assessment nested within WASH Benefits Bangladesh randomized controlled trial (NCT01590095). quantified
Abstract Background The WASH benefits Bangladesh trial multi-component sanitation intervention reduced diarrheal disease among children < 5 years. Intervention components included latrine upgrades, child feces management tools, and behavioral promotion. It remains unclear which most impacted diarrhea. Methods We conducted mediation analysis within a subset of households (n = 720) from the control arms. Potential mediators were categorized into indicators quality, use practices, practices....
Enteropathogens are major contributors to mortality and morbidity, particularly in settings with limited access water, sanitation, hygiene infrastructure. To assess transmission pathways associated enteropathogen infection, we measured household environmental conditions assayed 22 enteropathogens using TaqMan Array Cards stool samples from 276 six-month-old children living communities along a rural-urban gradient Northern Ecuador. We utilized multivariable models, risk factor importance,...
Reusing wastewater for irrigation is a longstanding practice that enhances crop yields and improves climate resilience. Without treatment, however, contains harmful pathogens chemicals. Reuse of untreated has been shown to be the health nearby communities, but routes exposure are unknown do not appear occupational. Some occur throughout entire such as food contamination. Other may spatially dependent, spread by domestic animals or through aerosolization.To examine whether those with spatial...
Measuring the impact of an environmental point source exposure on risk disease, like cancer or childhood asthma, is well-developed. Modeling how health hazard that extensive in space, a wastewater canal, not. We propose novel Bayesian generative semiparametric model for characterizing cumulative spatial to not well-represented by single space. The couples dose-response with log-Gaussian Cox process integrated against distance kernel unknown length-scale. show this well-defined inverse model,...
Deworming for pregnant women using a single dose of albendazole or mebendazole is recommended by the WHO in areas where baseline prevalence hookworm and/or trichuriasis >20%. However, other helminths and protozoa infecting are not affected these drugs dosages. To assess diversity intestinal helminth protozoan infections, we analyzed stool samples from recently enrolled into birth cohort, along rural-urban gradient northern coastal Ecuador 2019 to 2022. Participants provided sample their...
Disparities in access to water, sanitation, and hygiene within high-income countries are common often occur across racial/ethnic lines. The Arab-Bedouins Israel, a formerly nomadic ethno-national minority, have experienced displacement, forced sedentarization, poverty since Israel was founded. Land disputes with the government led precarious living arrangements, including unrecognized villages that considers illegal. We administered structured questionnaire one government-planned, two...
Background. Wastewater reuse for agriculture has intensified over the years partly due to increases in urbanization. In Valle del Mezquital, wastewater from Mexico City is used agricultural irrigation. Human and animal pathogens are continuously high wastewater, potentially putting local residents at risk. The Atotonilco Treatment Plant began partially treating May 2017, providing treated water some irrigation districts of Mezquital. Objective. We compared risk gastrointestinal diseases...
