The first positive test for WNV will be monitored by City crews and within 24 hours, crews will use adulticiding, a type of insecticide used to kill adult mosquitoes, in addition to the City’s normal larviciding program. As part of adulticiding, crews will use foggers in creek banks and City parks in the quarter-mile area where a positive trap is found. Prior to this taking place, residents will be notified via Blackboard connect to alert them of the fogging and positive test.

West Nile Virus (WNV) is a potentially serious virus, most commonly spread by infected mosquitoes. Mosquitoes become infected when they feed on infected birds. WNV can cause fever, inflammation of the brain, the lining of the brain, and the spinal cord. WNV can be transmitted year-round in Texas.
WNV often spreads by the bite of an infected mosquito. In a very small number of cases, WNV also has been spread through blood transfusions, organ transplants, breastfeeding, and pregnancy. WNV is not spread through casual contact such as touching or kissing a person infected with the virus.
Currently, there is no WNV vaccine available.
The incubation period is usually two to six days but ranges from two to 14 days.
