Soil transmitted helminthiasis (STHs) are endemic in Nepal but since the country territory is extremely heterogeneous, a multidisciplinary assessment is required to evaluate the risk of infection in different areas. Prevalence data were retrieved with systematic literature search and geographical coordinates were assigned to each survey site. Spatial stratification was then implemented considering land use and ecological parameters. STH transmission boundaries were tested after reference criteria and elevation was evaluated as additional predictor: the elevation threshold of 3057 m above sea level is demarking the STH transmission limit. Areas above this threshold are safe, but since lodging in at-risk sites is a compulsory stopover for international travelers, STH risk exposure should be considered for every travel to the country.
