目的评价广东省东莞市中堂镇为控制基孔肯雅热疫情所实施的媒介控制措施效果。方法在疫点及其周围,实施以蚊虫孳生地清除和成蚊消除等为主的媒介控制措施,并密切监测蚊媒密度(布雷图指数、房屋指数、容器指数、诱蚊诱卵指数等)的变化。结果防控措施实施3 d后,疫点布雷图指数下降至6.56;7 d后,布雷图指数下降了94.15%(由53.33降至3.12),房屋指数下降了92.51%(由41.67降至3.12),容器指数下降了71.19%(由14.75降至4.25)。诱蚊诱卵指数在首次监测(10月26日)中为0.75%,到11月4日降至0。结论在中堂镇采取的媒介控制措施,有效地控制了当地基孔肯雅热传播媒介伊蚊的密度,对控制基孔肯雅热疫情进一步扩散发挥了重要作用。
Objective To evaluate the effectiveness of the media control measures implemented in Zhongtang Town, Dongguan City, Guangdong Province to control the Chikungunya Fever epidemic. Methods Media control measures such as mosquito breeding and mosquito elimination were implemented in and around the epidemic areas and the mosquito density (Bretti’s index, house index, container index, mosquito-oviposition index, etc.) The change. Results After 3 days of implementation of the control measures, the Brettill index of the epidemic decreased to 6.56. After 7 days, the Brettilller index decreased by 94.15% (from 53.33 to 3.12) and the Housing Index decreased by 92.51% (from 41.67 to 3.12) , The container index dropped 71.19% (from 14.75 to 4.25). The mosquito oviposition index was 0.75% for the first monitoring (October 26) and dropped to 0 on 4 November. Conclusion The media control measures adopted in Zhongtang Town effectively controlled the density of the local Chikungunya heat transmission vector Aedes mosquito and played an important role in controlling the further spread of the Chikungunya fever.
