1972～1976年世界卫生组织与肯尼亚政府协作,在离基苏木20公里的一个湖畔乡村,对杀螟松喷洒抗疟的效果进行了评价。实验区人群比较稳定,未采取过抗疟措施。当地气候适宜于疟疾整年传播,属超高度疟区,以恶性疟为主,三日疟次之,蛋形疟和间日疟少见。已知传疟媒介为冈比亚按蚊 A 和 B 以 Between 1972 and 1976, WHO collaborated with the Kenyan government to evaluate the effectiveness of spraying fenitrothion on malaria control in a lakeside village 20 km from Kisumu. The experimental area population is relatively stable, did not take anti-malaria measures. The local climate is suitable for the year-round spread of malaria, which belongs to the ultra-high malaria area. It is predominantly falciparum malaria, followed by malaria on the third day, and egg-shaped malaria and vivax malaria are rare. Malaria vectors are known for Anopheles A and B of the Gambia
