Schistosomiasis in the Kavirondo District of Kenya Colony

Abstract

1. It is concluded that Physopsis nasuta is an intermediate host of S. bovis in Central Kavirondo. 2. The intermediate host of S. haematobium is probably P. nasuta or B. forskalii or possibly both. 3. It is fallacious to assume that the presence of furcocercariae of the “S. haematobium type” in snails proves that snail to be a vector of human schistosomiasis. 4. Further work is needed for the identification of the molluscan host in Kenya; a snail survey and an investigation of animal schistosomiasis would be of greater interest. 5. Certain prophylactic measures might be instituted.
