干旱区生态环境知识资源中心

Reclamation of land from the desert is currently taking place in all parts of Egypt. A side-effect of many of these projects has been the introduction of schistosome parasites and their snail intermediate hosts, sometimes among Bedouin population with no previous exposure to the disease. The purpose of the present study was to describe social, environmental and economic conditions which can affect the transmission and control of schistosomiasis in reclaimed areas, and to investigate how residents of these areas view local conditions. Two areas were found to have high rates of internal and external migration, many different social groups with widely divergent priorities and minimal contact with each other, and inadequate infrastructure in terms of roads, transport, water and sanitation and health services. As a result of these conditions, control strategies which are effective for the population living in the Nile Valley will have to be modified considerably if schistosomiasis is to be brought under control in reclaimed areas.
