目的 :评价 1999~ 2 0 0 0年福州市近郊发生登革热暴发流行后 ,为迅速扑灭疫情和预防隔年重新流行 ,在疫区及周边地区实施以灭蚊为主的综合性防制措施的效果。方法 :制定登革热防制与监测方案 ,开展卫生宣传 ,发动群众进行灭蚊和铲除蚊虫滋生地 ,用敌敌畏、12 .5 %高效氟氯氰菊酯悬浮剂或强力敌等化学药物杀灭蚊虫 ,以房屋指数、容器指数、布雷图指数及叮刺率等方法调查白纹伊蚊密度。结果 :1999年通过落实综合性防制措施 ,疫区防治前后的房屋指数分别为 6 3.3和 2 .1,下降率为 96 .7% ;容器指数分别为 5 5 .8和 10 .0 ,下降率为 82 .1% ;布雷图指数分别为 199.8和3.2 ,下降率为 98.4% ;防治前平均每户有 2个阳性积水容器 ,防治后仅有 0 .0 3个 ;刺叮率从防治前平均 42 .2只 / (人工·h)降至 0 ;10月 13日后未发现新的病人。 2 0 0 0年 6~ 11月份在 5个区共调查 6 2 0 0户居民住房 ,白纹伊蚊幼虫的房屋指数平均为 16 .7,容器指数平均为 12 .7,布雷图指数平均为 13.8,其中疫区上述 3项密度指数分别控制在 4.5、2 .2、2 .3以下 ,全年仅发病 3例。结论 :在政府的干预下 ,根据标本兼治 ,治本为主的原则 ,采取清除与管理滋生场所 ,灭蚊与防蚊等相结合的综合性防制措施 ,可迅速有效地遏阻登革热病的发生或流
OBJECTIVE: To evaluate the effectiveness of a comprehensive anti-mosquito control strategy in endemic areas and surrounding areas for the rapid suppression of the epidemic and the prevention of recurrent epidemics after a dengue outbreak in the suburbs of Fuzhou from 1999 to 2000. Methods: Develop dengue fever prevention and surveillance programs, publicize health information, mobilize the masses to eliminate mosquitoes and eradicate mosquito breeding grounds, and kill mosquitoes with dichlorvos, 12.5% beta-cypermethrin or powerful anti-chemical drugs, , Container index, Brettii index and sting rate and other methods to investigate Aedes albopictus density. Results: By implementing comprehensive control measures in 1999, the housing indices before and after the epidemic prevention and control were respectively 6 3.3 and 2.1, with the decreasing rate of 96.7%; the container indices were respectively 55.8 and 10.0, decreasing The rate was 82.1%; the Brettii index was 199.8 and 3.2 respectively, the rate of decrease was 98.4%; before the control, there were 2 positive water storage containers per household, with only 0.30 after the control; Before the average 42.2 / (artificial · h) dropped to 0; after October 13 no new patients were found. From June to November 2000, a total of 6200 residential dwellings were surveyed in 5 districts. The average house index of Aedes albopictus larva was 16.7, the average container index was 12.7, and the average Bretton’s index was 13.8, of which the three epidemic area density index were controlled at 4.5,2. 2,2 .3 the following year, only the incidence of 3 cases. Conclusion: Under the government intervention, according to the principle of tackling both the symptoms and the root cause, comprehensive prevention and control measures such as eliminating and managing breeding grounds, mosquito control and mosquito control can be quickly and effectively used to deter dengue fever Or stream
