Hurricane Harvey made a landfall on the Texas Gulf Coast on August 25, 2017, stalling over Harris County as a tropical storm for 4 days (August 26-29), dumping approximately 127 cm of rain. This tremendous amount of rainfall overwhelmed the county's natural and man-made drainage systems, resulting in unprecedented widespread flooding. Immediately following, Harris County Public Health Mosquito and Vector Control Division conducted a countywide emergency vector control response by integrating surveillance, control, and education strategies. This included landing rate counts, mosquito and avian surveillance, arbovirus testing, ground-based ultra-low volume (ULV) and aerial pesticide spraying, and community outreach. The immediate response lasted for 4 wk through September, resulting in 774 landing rates, 49,342 ha treated by ground-based ULV, 242,811 ha treated by aerial ULV, 83,241 mosquitoes collected, 1,807 mosquito pools tested, and 20 education/outreach sessions. Recovery activities of 3 additional education/outreach events continued through October while surveillance and control activities returned to routine status.
飓风“哈维”于 2017 年 8 月 25 日在德克萨斯州墨西哥湾沿岸登陆，作为热带风暴在哈里斯县停留了 4 天（8 月 26 日至 29 日），降雨量约为 127 厘米。大量的降雨淹没了该县的自然和人为排水系统，导致了前所未有的广泛洪水泛滥。随后，哈里斯县公共卫生蚊虫和病媒控制部门通过整合监测、控制和教育策略，对全县进行了紧急病媒控制响应。这包括降落率计数、蚊虫和鸟类监测、虫媒病毒检测、地面超低容量（ULV）和空中农药喷洒以及社区外展。紧急响应持续了 4 周，直到 9 月，共进行了 774 次降落率计数，地面超低容量处理了 49342 公顷，空中超低容量处理了 242811 公顷，收集了 83241 只蚊子，检测了 1807 个蚊子池，并开展了 20 次教育/外展活动。另外 3 次教育/外展活动的恢复活动持续到 10 月，而监测和控制活动则恢复到常规状态。
