澄迈县历史上曾是以微小按蚊为主要媒介的高疟区。经多年采取综合性灭疟措施后,微小按蚊得到有效的控制,疟疾发病率大幅度下降,近年来本地居民本地感染发病率均控制在万分之一以下,但仍有一定数量的疟疾病例发生。本文对近三年(1987～1989)发生在本县的所有疟疾病例进行分析,以期了解病例感染来源及其在不同人群中的分布规律,为采取灭疟措施,巩固灭疟成果提供依据。
Chengmai County historically had a high malaria area with Anopheles minimus as the main vector. After many years of comprehensive malaria control measures, Anopheles minimus has been effectively controlled and the incidence of malaria has dropped drastically. In recent years, the incidence of local infections among local residents has been controlled below 1%, but a certain number of malaria cases still exist occur. This article analyzes all malaria cases occurred in this county in the recent three years (1987 ~ 1989) in order to understand the source of case infection and its distribution in different populations, and provide the basis for taking measures to eliminate malaria and consolidate the achievement of malaria elimination.
