目的白纹伊蚊是登革热的传播媒介。在登革热爆发流行区实施以灭蚊为主的综合性防制措施,以迅速使疫情得到控制。方法开展以健康教育、环境治理、清除蚊虫滋生场所为主的爱国卫生运动;使用高氯残杀威、辛硫高氯氟等杀虫剂实行滞留喷洒和空间喷洒灭蚊。灭蚊前、后调查白纹伊蚊种群密度,容器指数、布雷图指数评价防制效果。结果灭蚊前白纹伊蚊容器指数12.4,布雷图指数68;第一次灭蚊后分别下降为2.9和16,第二次灭蚊后容器指数与布雷图指数均降为0;白蚊伊蚊密度从灭蚊前平均13.7只/人工小时下降为零,10月8日宣布疫情流行终止。结论根据标本兼治,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疫情的发生或流行。
Purpose Aedes albopictus is a dengue vector. A comprehensive anti-mosquito control program should be implemented in the endemic area of dengue outbreak so as to promptly control the epidemic. Methods Patriotic public health campaigns focusing on health education, environmental management and mosquito breeding were carried out. Insecticides such as chlorfluazuron and chlorothalofurrin were used for decontamination and space spraying. Mosquito control before and after investigation of Aedes albopictus population density, container index, Brett index evaluation of the control effect. Results Before Aedes albopictus, the index of Aedes albopictus was 12.4 and the Brett index was 68. After the first mosquito control, the Aedes albopictus index dropped to 2.9 and 16 respectively. After the second mosquito control, the container index and Brettiler index decreased to 0, The density of mosquitoes dropped from an average of 13.7 / artificial hours before mosquito control to zero, and the epidemic was terminated on October 8. Conclusion According to the principle of treating both the root cause and the root cause of the disease, comprehensive prevention and control measures should be taken to eliminate and manage breeding grounds, mosquito control and mosquito control, which can quickly and effectively deter the occurrence or prevalence of dengue fever.
