A pocket chart to estimate true Schistosoma mansoni prevalences

Parasitol Today. 1993 Aug;9(8):305-7.

Abstract

In a recent paper, Sake de Vlas and Bruno Gryseels have explored the extent and implications of the underestimation of Schistosoma mansoni prevalences, as measured by faecal screening. Together with Gernt van Oortmorssen, Anton Polderman and Dik Habbema, they now present a practical and generally applicable chart to infer 'true' prevalences from simple egg count surveys.
