Household-level prevalence of helminth infection.
Household prevalence of A egg-positive N. americanus mono-infection B egg-positive S. mansoni mono-infection and C N. americanus -S. mansoni co-infection among 1208 individuals living in 275 households. Values were calculated for an area of 200 m around each household and assigned to Thiessen polygons drawn on the basis of household positions.
