疟疾发病率的正确评价对于揭示流行趋势,确定输入病例到什么程度可引起传播,以及有效防治后疟疾的发生和扩散都是需要的。Sinton估计1935年印度有1亿人患疟疾,开展国家灭疟运动规划的1952年之前,每年有7,500万疟疾病例和1%的病死率。到全国灭疟运动后疟疾回升,1976年升到最高峰达600万,1978年下降为270万。但是实际发病率约为官方统计数的2～10倍以
Correct evaluation of the incidence of malaria is needed to shed light on epidemiological trends, determine the extent to which imported cases can cause transmission, and the prevention and treatment of post-malaria occurrence and spread. Sinton estimates that 100 million people in India were malaria-infected in 1935 and 75 million cases of malaria and 1% fatality each year until 1952 when the National Malaria Campaign was under way. Malaria rose after the national anti-malaria campaign rose to a peak of 6 million in 1976 and dropped to 2.7 million in 1978. However, the actual incidence of about 2 to 10 times the official statistics
