Bilharzia study

Freshwater snails from Aquarap 2000 survey

HOORC's Library had a visit today from Professor C.C. Appleton of the University of KwaZulu-Natal, who is working with Professor Fred Ellery on a retrospective analysis of the bilharzia epidemic in the Maun area during the 1970s and 1980s. The study relates hydrological data to the available disease prevalence data and suggests that there is a six year lag between occurrence of high water discharges into the Thamalakane River and the disease assuming public health importance. In HOORC's Library, you can find Professor Appleton's Freshwater molluscs of Southern Africa : with a chapter on Bilharzia and its snail hosts.
