[The course of malaria control and present status in Zhejiang Province].

Through forty years' sustained efforts in the prevention and treatment of malaria in Zhejiang Province, the malaria incidence dropped from 76.650/000 in the Fifties to 0.910/000 in the Eighties. Three malaria epidemics emerged in 1954, 1962 and 1973, respectively, among them the epidemic in 1962 was the most serious one with 0.88 million cases reported and an incidence of 3300/000. The annual incidence of the overall counties/cities was below 10/000 after 1988. Only 172 malaria cases were found in 1992, the incidence being 0.040/000. No indigenous malaria case was found in 38 counties in 1992, accounting to 43.7% of the total malaria endemic counties. The number of imported malara cases was 3,829, amounting to 89.2% of the total number of cases. Through the spot-check of the Ministry of Public Health in 1993, it was confirmed that the criteria of basic elimination of malaria in the province was attained.
