The impact of heavy rainfall events on waterborne diarrheal diseases is uncertain. We conducted weekly, active surveillance for diarrhea in 19 villages Ecuador from February 2004 to April 2007 order evaluate whether biophysical and social factors modify vulnerability events. A event was defined as 24-hour exceeding the 90th percentile value (56 mm) a given 7-day period within study period. Mixed-effects Poisson regression used test hypothesis that prior 8 weeks, water sanitation conditions,...

Agricultural workers worldwide exposed to heat stress could be at the risk of kidney injury, which lead chronic disease an unknown origin (CKDu). Hydration has been promoted as a key measure reduce injury. In presence hydration intervention, incidence acute injury (AKI) was calculated in sugarcane worker population Guatemala and several factors were evaluated. We measured function beginning end work shift three time points 517 workers. defined AKI increase serum creatinine 26.5 µmol/L or 50%...
SARS-CoV-2 emerged in 2019 and has become a major global pathogen. Its emergence is notable due to its impacts on individuals residing within long term care facilities (LTCFs) such as rehabilitation centers nursing homes. LTCF residents tend possess several risk factors for more severe outcomes, including advanced age multiple comorbidities. Indeed, of LTCFs represent approximately 40% deaths the United States. To assess prevalence incidence among workers, determine extent asymptomatic...
Objective To estimate the disease burden attributable to unsafe water and poor sanitation hygiene in China, identify high-burden groups inform improvement measures.Methods The China was estimated for diseases resulting from exposure biologically contaminated soil (diarrhoeal disease, helminthiases schistosomiasis) vector transmission inadequate management of resources (malaria, dengue Japanese encephalitis).The data were obtained China's national infectious reporting system, helminthiasis...
Documenting Long COVID cases has been challenging partly due to the lack of population-level data and uncertain diagnostic criteria, hindering ability ascertain healthcare utilization patterns over time. The objective this study is examine characteristics patients in Colorado pre- post-diagnosis compared controls. Retrospective, longitudinal case-control using a 100% sample Colorado's All-Payer Claims Database. includes individuals 18 or older diagnosed with between October 1, 2021, August...
Background Schistosomiasis has reemerged in China, threatening schistosomiasis elimination efforts. Surveillance methods that can identify locations where are needed to prevent the further spread of infections. Methods and Principal Findings We tested humans, cows, water buffalo intermediate host snail, Oncomelania hupensis, for Schistosoma japonicum infection, assessed snail densities extracted regional surveillance records areas Sichuan province. then evaluated ability villages human...
Climate change has implications for human health and productivity. Models suggest that heat extremes affect worker health, reduce labor capacity, commodity supply. Chronic conditions are on the rise internationally. However there is a paucity of direct empirical evidence relating increasing temperatures to both agricultural productivity.We evaluated relationship between temperature exposure, kidney function, two measures productivity-tons produced job attrition, 4,095 Guatemalan sugarcane...
To combat and eventually eliminate the transmission of liver fluke Opisthorchis viverrini, an accurate practical diagnostic test is required. A recently established urine antigen detection using monoclonal antibody-based enzyme-linked-immunosorbent assay (mAb-ELISA) has shown promise due to its high accuracy use in place fecal samples. further utility this assay, we performed a cross sectional study 1,043 people 3 opisthorchiasis endemic communities northeast Thailand by applying together...
Our work comprises unique data on the characteristics of SARS-CoV-2 dynamics among staff working at LTCFs in early months pandemic prior to mandated surveillance testing. During this time period, LTCF residents were largely sheltering-in-place.
Cockroaches and mice, which are common in urban homes, sources of allergens capable triggering asthma symptoms. Traditional pest control involves the use scheduled applications pesticides by professionals as well pesticide residents. In contrast, integrated management (IPM) sanitation, building maintenance, limited least toxic pesticides.We implemented evaluated IPM compared with traditional practice for its impact on pests, allergens, use, resident satisfaction a large public housing...
Triggered by a fascinating publication in the New England Journal of Medicine detailing China's new multi-pronged strategy to control and eventually interrupt transmission Schistosoma japonicum, this PLoS Neglected Tropical Diseases Debate critically examines generalizability financial costs studies presented from marshlands lake region. Edmund Seto University California colleagues emphasize that epidemiology schistosomiasis varies according social-ecological context. They conjecture...
We studied 226 low-income households as a part of the Colorado Home Energy Efficiency and Respiratory Health (CHEER) study to investigate relationship between energy-efficiency retrofits (EERs) specific air sealing residential building envelopes, annual average infiltration rates (AAIR), qualitative indicators “healthy” homes. Blower door tests quantified leakage area in each home, which was used estimate AAIR. Walk-through inspections were record observations air-sealing conducted...
Sensitive Schistosoma japonicum detection methods are needed to progress from schistosomiasis control elimination. The sensitivity of the Kato-Katz thick smear and miracidium hatching tests decrease with infection intensity serological cannot always identify current infections. We evaluated a fecal polymerase chain reaction (PCR) assay detect S. in 106 humans 8 bovines China. PCR was highly sensitive, detecting DNA at 0.5 eggs/g stool. Comparing examination single stool sample test using...
