基本消灭疟疾后简化疟疾监测方法的研究

STUDY ON SIMPLIFIED METHODS OF SURVEILLANCE IN AREAS OF MALARIA BASICALLY ELIMINATED

本文报道了上海市闵行区和南汇县于1992—1994年分别实施简化的甲、乙两种疟疾监测方案.结果表明:两地3年平均发病率比前3年分别下降66.05%和63.16%.目前两试点区发病率低,病例呈散在分布,疟疾发病以输入病例为主,占发病总数的75.0%.作者认为,在上海市疟疾基本消灭地区,对本地居民疟疾监测建议采用乙方案,对外来流动人口可采用甲方案监测,似可达到事半功倍的效果.

Malaria in Shanghai has been basically eliminated since 1980s. In order to select a simplified surveillant method,two schemes of surveillance A and B were performed in Minhang district and Nanhui county,Shanghai suburb,respectively from 1992 to 1994. Results showed that the malaria incidence in both pilot areas had decreased 66.05% and 63.16% during three -year period of surveillance. Most of malaria cases (75.0%) were imported. These results suggested that scheme B was same effective as scheme A in malaria surveillance but save the time,labour and cost. However,the mobile population should be strictly put under scheme A to prevent imported malaria transmission.
