萨拉索塔县确认一例本地感染西尼罗病毒病例：卫生部门发布蚊媒疾病预警
佛罗里达州卫生部萨拉索塔县分部10月23日发布蚊媒疾病预警，确认当地出现一例本地感染的人类西尼罗病毒病例。县卫生部门与萨拉索塔县蚊虫管理部门已协调开展监测与防控，并在相关区域实施了蚊虫消杀作业。
据卫生部门介绍，西尼罗病毒主要侵袭中枢神经系统，可引发严重疾病；不过约80%的感染者不会出现任何症状。传播该病毒的主要蚊种为库蚊，包括南方家蚊，这类蚊子在湿热环境中大量繁殖，常见于居民后院。病毒通常在鸟类与蚊子之间循环，蚊子叮咬受感染的鸟后再叮咬人即可传播。
卫生部门表示，将继续对包括西尼罗病毒、东方马脑炎、圣路易斯脑炎、疟疾、基孔肯雅热与登革热在内的蚊媒疾病开展全州监测，并呼吁居民发现死鸟时向佛罗里达州鱼类与野生动物保护委员会报告，以协助监测疫情。

Sarasota County Confirms Locally Acquired West Nile Virus Case; Health Advisory Issued
The Florida Department of Health in Sarasota County issued a mosquito-borne illness advisory on October 23 after confirming a human case of locally acquired West Nile virus. The county health department and Sarasota County Mosquito Management Services have coordinated surveillance and prevention, and mosquito control treatments have already been conducted in the area.
According to the health department, West Nile virus affects the central nervous system and can cause serious illness, though about 80 percent of infected people show no symptoms. The virus is carried mainly by Culex mosquitoes, including the southern house mosquito, which thrives in hot, humid conditions and commonly flourishes in backyards. The virus normally circulates between birds and mosquitoes, and can spread to people when a mosquito bites an infected bird and then a person.
The department said statewide surveillance continues for mosquito-borne illnesses including West Nile virus, Eastern equine encephalitis, St. Louis encephalitis, malaria, chikungunya and dengue, and encouraged residents to report dead birds to the Florida Fish and Wildlife Conservation Commission to assist monitoring.
