江苏省恶性疟防治研究

为了解江苏省恶性疟的流行特点和媒介传疟作用，制定有效的防治对策以尽快控制和消灭恶性疟，我们通过多年大量的现场流行病学调查和实验研究，证实嗜人按蚊是江苏省传播恶性疟的主要媒介。根据调查和研究结果，在全省恶性疟流行区采取了大范围持续的室内滞留喷洒灭蚊，和药物浸泡蚊帐巩固灭蚊，同时抓好传染源和易感人群的综合防治措施，结果在较短时间内控制了恶性疟的流行，并大幅度降低了间日疟发病率。经多年疟疾监测证实，已连续８年未发生当地感染的恶性疟病例，达到基本消灭恶性疟的标准，取得了显著的防治效果。

INVESTIGATION OF FALCIPARUM MALARIA CONTROL IN JIANGSU PROVINCE

Epidemiological investigation and field experimental studies for malaria control were carried out in Jiangsu province in order to speed up the progress of control and elimination of P.falciparum through understanding epidemiological and vectorial transmission characteristics,and through formulating and implementing the control strategy. Results of the investigation at a large scale indicated that transmission of P.falciparum depended on the An.anthropophagus which served as the main vector for falciparum malaria in Jiangsu province.In accordance with the above results,the control strategies were formulated and implemented in endemic areas of Jiangsu,which were the applications of indoor residual spraying and insecticide impregnation of mosquito nets in combination with strengthened management of infective sources and susceptible population.As a result of the strategy,transmission of P. falciparum was effectively intercepted within a short period with a reduction of incidence of vivax malaria,and there had been no indigenous falciparum malaria cases in Jiangsu for 8 consecutive years.Basic.eradication of falciparum malaria has been achieved in Jiangsu province.
