Abstract The distribution of certain permissive intermediate snail host species in freshwater is a crucial factor shaping transmission intestinal schistosomiasis, neglected tropical disease that causes much human suffering Africa. To shed new light on southern Malawi, where cases schistosomiasis have been found, repeated malacological surveys were conducted Chikwawa and Nsanje Districts the Lower Shire Valley, to detect characterize populations Biomphalaria , for schistosomiasis. Sampling took place across total 45 sites, noting water conductivity, pH, temperature, dissolved salts (TDS) geographical elevation. presence or absence snails was predicted upon physiochemical environmental conditions Random Forest modelling. Water TDS elevation most important predicting abundance with temperature pH slightly less roles. This first report B. pfeifferi Valley enhances understanding factors strongly associate allow prediction its local distribution. represents useful step towards developing appropriate intervention strategies mitigate transmission.
