摘要：Although no full-scale survey of the prevalence of bilharziasis in Swaziland has been carried out, examinations of schoolchildren have revealed S. mansoni infection rates of up to 49% in some areas, and S. haematobium infection rates ranging from 3% to 75%. The highest prevalence occurs in areas where there are thickly populated African reserves, or irrigation schemes. The spread of infection is encouraged by the use of rivers, dams and canals for bathing and washing purposes. Preventive measures are recommended, including the provision of more suitable bathing, washing and latrine facilities for the population, the control of waste waters, and the use of molluscicides.
