目的 :清除残存嗜人按蚊 ,阻断疟疾传播。方法 :搜索残存嗜人按蚊 ,实施溴氰菊酯浸泡蚊帐灭蚊 ,复查所有嗜人按蚊分布点 ,评价清除效果。结果 :1989～ 1994年 ,于建阳、武夷山、邵武、顺昌和三元等县 (市、区 )发现残存嗜人按蚊分布点 42个 ,嗜人按蚊占人房按蚊组成的 2 6 .2 0 %。 2 0 0 1年完成闽北地区灭蚊后全部嗜人按蚊分布点的复查工作 ,95 .80 %分布点经 2～ 3次以上反复性复查 ,最多达 12次 ,所有复查点均未再捕获嗜人按蚊。1988年清除工作前 ,分布区疟疾发病 1381例 ,年发病率为 4.47/万。采取措施后 ,疟疾发病率显著下降 ,1995年后 ,嗜人按蚊分布区未再发生疟疾暴发流行。 1998～ 2 0 0 1年 ,未发现当地疟疾感染者。结论 :闽北地区嗜人按蚊已被清除 ,当地疟疾传播得到有效阻断。
Purpose: To eliminate the remaining Anopheles anthropophagus and to stop the spread of malaria. Methods: search for the remaining anopheles anthropophagus, the implementation of mosquito nets soaked in deltamethrin, review of all Anopheles anthropophagus distribution points to evaluate the clearance effect. Results: From 1989 to 1994, 42 sites of Anopheles anthropophagus were found in counties (cities and districts) of Jianyang, Wuyishan, Shaowu, Shunchang and Sanyuan, with anopheles anthropophagus accounting for 26 .2 0%. The review of the distribution of An. Anopheles anthropophagus after the mosquito control in northern Fujian was completed in 2001. 95.80% of the distribution points were repeatedly checked up to 12 times more than 2 times and 3 times, up to 12 times Capture anopheles. Before the removal of work in 1988, the incidence of malaria in the distribution area was 1381, with an annual incidence of 4.47 / million. After taking measures, the incidence of malaria dropped significantly. After 1995, there was no recurring malaria outbreak in the Anopheles anthropoid area. Between 1998 and 2001, no local malaria infection was found. Conclusion: Anopheles anthropophagus in northern Fujian has been cleared, and local malaria transmission has been effectively blocked.
