目的为国内外宾客营造良好的卫生安全环境,预防与控制传染病的发生和流行,为做好突发公共卫生事件的应急消杀处置提供依据。方法采用有效粉迹法对2012年广西南宁中国-东盟博览会指定南宁市4家大型驻点酒店进行灭前、灭后鼠密度调查分析。结果灭前鼠密度为19.51%,灭后鼠密度为2.85%,灭鼠率为85.39%,卡方值χ2=204.457 2,P<0.05,有差异,具有统计学意义;鼠类依次为褐家鼠、黄胸鼠、小家鼠,但χ2=2.627 3,P=0.268 8,P>0.05,无差异,没有统计学意义。结论此次调查为中国-东盟博览会顺利召开提供有利条件,也为病媒生物的监测与效果评估提供科学依据。
Objective To create a good health and safety environment for domestic and foreign guests, prevent and control the occurrence and prevalence of infectious diseases, and provide the basis for emergency dismantlement and disposal of public health emergencies. Methods The effective moulting method was used to investigate the density of rats in four large-scale hotels in Nanning during the 2012 Nanning China-ASEAN Exposition designated as pre-extinction and extinction. Results The density of ex-ante mice was 19.51%, the density of rats after extinction was 2.85%, the rate of extermination was 85.39%, chi-square value was 204.457 2, P <0.05, with statistical significance; Rattus flavipectus, Mus musculus, but χ2 = 2.627 3, P = 0.268 8, P> 0.05, no difference, no statistical significance. Conclusion The survey provided favorable conditions for the successful convening of the China-ASEAN Expo and provided a scientific basis for the monitoring and evaluation of vector-borne diseases.
