Abstract

The incidence of malaria in Yunnan province has decreased year by year in recent years. However, focal outbreaks in small scale still occurred every year. The average morbidity in villages with outbreaks was 15.22-70.82%, and the plasmodium positive rate 6.36-34.69%, in which the percentage of Plasmodium falciparum 34.55-63.63%. The main cause of outbreaks was the existence of residual source of malaria infection and the concomitance of high density of Anopheles. Eradication of the vector and eradication of the course of infection were taken as the composite preventive and control measures which gave a satisfactory effect.

摘要

近年来，云南省疟疾发病率逐年下降。然而，每年仍有小规模的局部暴发。暴发村庄的平均发病率为15.22%-70.82%，疟原虫阳性率为6.36%-34.69%，其中恶性疟原虫所占百分比为34.55%-63.63%。暴发的主要原因是存在疟疾感染残余源以及高密度按蚊的并存。采取灭蚊和阻断感染途径的综合防治措施，效果良好。
