摘要:

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。

Abstract:

Objective To evaluate the vector control effect in a chikungunya epidemic in Zhongtang town, Dongguan city. Methods Mosquito breeding places were eliminated and the vectors killed at the epidemic sites. The mosquito density and related indicators were monitored. Results The breteau index (BI) reduced to 6.56 after 3 days of control, and decreased by 94.15% beyond 7 days (from 53.33 to 3.12). On day 7, the house index (HI) decreased by 92.51% (from 41.67 to 3.12) and the container index (CI) by 71.19% (from 14.75 to 4.25). The mosqito-ovitrap index was 0.75% in the first surveillance (on October 26) and reduced to 0 on November 4. Conclusion The vector control measures in Zhongtang town effectively reduced the Aedes density and prevented the spread of chikungunya epidemic.
