Enhancing Cholera Control in Nepal (ECHO-N)

2023, International Vaccine Institute

The survey estimated the sero-incidence of recent Vibrio cholera O1 infection in Nepal using cross-sectional serologic markers. The study assessed correlation between self-reported diarrheal symptoms and Vibrio cholera immunological markers in individuals; conducted geospatial analysis to identify priority intervention areas (i.e., cholera hotspots); assessed correlation between acute watery diarrhea surveillance data in the national reporting system and estimated recent incidence of Vibrio cholera infection in geographically defined areas. New ERA conducted national representative cross-sectional survey to collect risk factors associated with diarrheal diseases, and collected serum sample for laboratory testing.
