Screening for schistosomiasis with questionnaires.

Abstract

New schistosomiasis control initiatives have been launched to reduce significantly the current global burden of this disease, mainly through regular administration of praziquantel to schoolchildren living in endemic areas. Because schistosomiasis is distributed focally, epidemiological tools for rapid and inexpensive identification of communities at highest risk of morbidity are required to target praziquantel most efficiently. This article outlines the development and validation of simple questionnaires for screening of Schistosoma haematobium and Schistosoma mansoni in sub-Saharan Africa.
