Animal feces contribute to domestic fecal contamination: Evidence from E. coli measured in water, hands, food, flies and soil in Bangladesh

Study provides empirical evidence of fecal transmission in the domestic environment despite on-site sanitation. Animal feces contribute to fecal contamination, and fecal indicator bacteria do not strictly indicate human fecal contamination when animals are present.

Detecting and enumerating soil-transmitted helminth eggs in soil: New method development and results from field testing in Kenya and Bangladesh

Research coauthored by WHD researchers Lauren Steinbaum, Laura Kwong, Alexandria Boehm and Amy Pickering presents an effective new approach to detecting in soil eggs of a worm that that infects about 1.5 billion people. The method is appropriate for low-resource settings, and could be used for standardizing detection of the worm globally.

Occurrence of norovirus in raw sewage – A systematic literature review and meta-analysis

Human noroviruses (NoV) are a leading cause of recreational waterborne illnesses and responsible for the majority of viral-associated gastrointestinal illnesses nationwide. The researchers conducted a systematic literature review of published peer-reviewed publications to identify NoV density data in wastewater influent, and provided an approach for developing pathogen density distributions, using the NoV data. Their results are the first to quantitatively characterize seasonal and geographic differences, which could be particularly useful for future risk assessments.

Hand- and Object-Mouthing of Rural Bangladeshi Children 3–18 Months Old
Laura Kwong, Ayse Ercumen, Amy Pickering, Leanne Unicomb, Jenna Davis, Stephen Luby

Children are exposed to environmental contaminants by placing contaminated hands or objects in their mouths. We quantified hand- and object-mouthing frequencies of Bangladeshi children and determined if they differ from those of U.S. children to evaluate the appropriateness of applying U.S. exposure models in other socio-cultural contexts. We found that both hand- and object-mouthing frequencies were higher for Bangladeshi compared to U.S. children.

Disgust, Shame, and Soapy Water: Tests of Novel Interventions to Promote Safe Water and Hygiene

Study of residents of slum compounds in Dhaka, Bangladesh finds neither a traditional, health-based message nor a new disgust-and-shame message led to high levels of chlorination during a free trial, nor to high willingness to pay for the chlorine at the end of the free trial. Provision of low-cost hand-washing facilities did increase hand washing, although the effect size was modest.
