郑州地处黄淮平原,系以中华按蚊为传播媒介的间日疟流行区,一九七○年发病率达259/万。近些年来,经采取以防治传染源为主和加强防蚊灭蚊的综合性措施,发病率持续下降,一九八三年已降至1.22/万。在发病率较低的情况下,我们对今年的230例疟疾病例(占全年发病总数的95.0%)进行了个案调查,以探讨本地当前发病特点和传播因素,区外感染程度与本地发病的关系,以及评价防治效果等。现将调查结果分析如下:
Located in the Huanghuai Plain, Zhengzhou is an epidemic area where the Anopheles sinensis is the media of transmission. The incidence rate in 1970 was 2,590,000. In recent years, the incidence rate has continued to decline with a comprehensive approach to preventing and controlling mosquito sources and mosquito control. It dropped to 1.22 per thousand in 1983. In the case of low incidence, we conducted a case-study on 230 malaria cases (95.0% of the total annual incidence) in this year to explore the current local incidence and transmission factors, the degree of extra-regional infection and the incidence of local disease Relations, and evaluation of prevention and treatment effects. The survey results are as follows:
