福建省嗜人按蚊残存分布区的疟疾监测

SURVEILLANCE ON MALARIA IN RESIDUAL REGION OF ANOPHELES ANTHROPOPHAGUS IN FUJIAN

目的 考核福建省以嗜人按蚊为主要传疟媒介区的疟疾防治效果。 方法 1988年起对该类区的疟疾与媒介实行监测 ;1998～ 2 0 0 0年按照卫生部 WHO的课题 ,选择建阳市童游镇和邵武市水北乡实施纵向监测。每年在疟疾流行季节 (7～ 10月 ) ,组织专业人员 ,捕捉原嗜人按蚊村人房 (帐内 )按蚊 ,鉴定蚊种并计算密度 ;对发热者采血镜检疟原虫。 结果 对原该蚊分布的 2 63个和 2个村的纵向观察 3年 ,均未再捕到嗜人按蚊。发热病人血检疟原虫阳性者从 1988年的 13 15例降至 2 0 0 1年的 3例。 结论 福建省抗疟措施有效 ,防治成果巩固。

Objective To evaluate the effect of malaria control in the area where the main transmission vector was Anopheles anthropophagus in Fujian Province. Methods The surveillance of both malaria cases and vectors has been conducted in the area since 1988. Two villages in Tongyou Town,Jianyang City and Shuibei Twon,Shaowu City were selected for longitudinal observation respectively. The items included capturing Anopheles in nets or rooms,identifying the species,calculating density,and detecting plasmodium in blood film for fever patients,every year during malaria epidemic season. Results No An. anthropophagus was caught in 263 villages formerly distributed the kind of mosquito and in two longitudinal observation spots. The No. of fever patients with plasmodiun positive reduced from 1 315 in 1988 to 3 in 2001. Conclusion The malaria control measures in Fujian are effective and the achievement is solidified.
