The greatest burden of STH and schistosomiasis occurs in sub-Saharan Africa (SSA) and this region has the most immediate need for reliable, up-to-date distribution maps.
Until recently, only a handful of countries in SSA had conducted national surveys of worms, with information for most countries scattered across the literature and not catalogued. The developed maps collate available STH and schistosomiasis information into a single database and present the known distribution of infection and areas without suitable data.
Also presented are maps showing the current and historic coverage of national programmes to eliminate lymphatic filariasis.
