新疆伊犁地区疟疾调查和防治研究

EPIDEMIOLOGIC SURVEY AND CONTROL OF MALARIA IN YILI DISTRICT, XINJIANG

Yili District was one of the main malaria regions in Xinjiang. It could be divided, according to the temperature, elevation and epidemic conditions, into 3 types of areas-the non-malaria area, the unstable and stable malaria areas. The main plasmodium was P. vivax, including the long and short prepatent period strains and, there were also P. faciparum and P. malariae in the lower reaches of the Yili River. Anopheles messeae, A. hyrcanus and A. claviger were found and their breeding sites, seasonal variations, blood sucking and perching characters were investigated. A. messeae was found to be the main vector of the disease. Based on the indoor perching habit of A. messeae and the effect of DDT on malaria control by indoor detained spray, measures were taken to cure patients and prevent relapse in springs. In areas with high incidence, DDT was sprayed indoors in order to maximally diminish infective sourses, the efforts were crowned with great success.
