Assessment of microbial risks by characterization of Escherichia coli presence to analyze the public health risks from poor water quality in Nepal.

The combination of natural disasters and inadequate infrastructure introduce unique challenges in providing safe drinking water in low-income countries. For example, Nepal faces several challenges in managing sporadic diarrheal outbreaks across the country, given its complex geographic terrain, and its susceptibility to extreme natural events like earthquakes, floods, and landslides. To assess the risks of diarrheal diseases caused by fecal contamination in several water sources in different geographical regions of Nepal, we conducted a two months cross-sectional study throughout 37 out of 75 districts in Nepal, including the ones affected by Nepal 2015 earthquake.
