Abstract:

Objective: To analyze the situation of vector control in the 7th Military World Games in 2019, so as to provide a scientific basis for vector control in similar major events in the future. Methods: The surveillance results of major vectors in different types of places (venues, hotels, designated hospitals, etc.) in urban areas of Wuhan, China from June to September 2019 were analyzed. Excel 2007 and SPSS 23.0 softwares were used for data processing. The Chi-squared test and Fisher's exact test were used for data analysis. Results: In June, the positive rate of fly breeding sites, the infestation rate of nymph and adult cockroaches, and the detection rate of cockroach eggs were highest, which were 3.88%, 1.69%, and 0.06%, respectively. In July, the positive rate of indoor rodent trace, mosquito larval route index and dip index, and indoor fly density were highest, which were 2.91%, 1.31 stagnant waters per km, 4.20%, and 4.81%, respectively; the qualified rates of rodent-proof and fly-proof facilities were lowest, which were 85.97% and 87.84%, respectively. In August, the outdoor rodent density route index and adult mosquito landing index were highest, which were 1.04 rodents and 1.63 mosquitoes per person, respectively. Conclusions: Authorities should continuously monitor vector infestation and control effects in key places of Wuhan Military World Games, scientifically and effectively evaluate the implementation of vector control, and timely detect relevant problems and adjust response strategies to prevent the occurrence of emergencies.

摘要：

目的: 分析2019年第七届世界军人运动会（军运会）病媒生物防制保障工作开展情况，总结经验并为今后类似大型赛事活动的病媒生物防制保障工作提供科学依据。方法: 分析2019年6－9月武汉城区范围内军运会各类场馆、酒店、定点医院等不同类型单位（场所）的重要病媒生物监测结果。用Excel 2007和SPSS 23.0软件处理数据；采用χ²检验、Fisher精准检验进行统计分析。结果: 监测结果显示，6月蝇类孳生地阳性率、蜚蠊成若虫侵害率和卵鞘查获率均最高，分别为3.88%、1.69%和0.06%；7月室内鼠迹阳性率、蚊幼虫路径指数、采样勺指数和室内蝇密度（有蝇房间阳性率）均最高，分别为2.91%、1.31处/km、4.20%和4.81%，防鼠、防蝇设施合格率均最低，分别为85.97%和87.84%。8月外环境鼠密度路径指数和成蚊停落指数最高，分别为1.04处/km和1.63只/人次。结论: 管理部门应实时掌握军运会重点单位（场所）的病媒生物侵害现状及防制效果，科学有效地评估军运会病媒生物防制保障工作开展情况，并及时发现相关问题，调整应对策略，防止突发事件的发生。
