[Analysis of causes of malaria outbreaks in Yunnan Province, 1981-1985].
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.
