苏丹流行血吸虫病已久,据1933年调查全国15个省有12个省流行血吸虫病,其中流行埃及血吸虫病的有10个省、流行曼氏血吸虫病的有6个省。吉齐拉灌溉地区面积约500万公顷,有170个村庄和少数市镇,人口约1,500,000。该地区为世界闻名的灌溉植棉试验区,也是苏丹主要经济收入的产棉区。从1924年大规模水利工程实施后,大批外来的农业工人带进了各种血吸虫及其中间宿主螺蛳,虽经采取了一些控制措施,血吸虫病仍然是重要的公共卫生问题。 1940～49年先后两次分别调查了80,000
The prevalence of schistosomiasis in Sudan has long been high. According to a survey conducted in 1933, there were 12 endemic schistosomiasis in 15 provinces in the country, among which 10 were endemic to Egypt and 6 were endemic to Schistosoma mansoni. The irrigated area of Jizzila is about 5 million hectares and has 170 villages and small towns with a population of about 1,500,000. The region is a world-renowned experimental zone for irrigated cotton and cotton, and also a cotton-producing area for major economic income in Sudan. After the large-scale water conservancy project was implemented in 1924, a large number of foreign agricultural workers brought in various schistosomes and their intermediate host snails. Despite some control measures, schistosomiasis is still an important public health issue. Between 1940 and 49, 80,000 were investigated twice
