Denton County West Nile Virus Notice




Denton County reports second West Nile Virus Case and Positive Mosquito Pool


July 26, 2016 – Denton County Public Health (DCPH) is reporting its second human case of West Nile Virus (WNV) for 2016 in Denton County. The resident lives in Carrollton and was diagnosed with West Nile Fever. The positive mosquito pool is located in an unincorporated section of Denton County east of Oak Point (east of FM 720).


DCHD will conduct ground spraying in the area for two consecutive nights, beginning Wednesday, July 27. The ground spraying schedule is as follows, weather permitting:


  • Wednesday, July 27 between the hours of 9pm and 5am
  • Thursday, July 28 between the hours of 9pm and 5am


A detailed map of the spray area can be found at dentoncounty.com/WNVnews. Residents in the affected area are being informed.


Chief Epidemiologist Juan Rodriguez stresses that residents can play a large role in reducing their risk. “It is important for residents to drain standing water around their homes, take precautions to prevent mosquito bites while outdoors, dress appropriately and use DEET or other EPA-approved repellents,” he states.


Residents should take the following steps to reduce their risk of getting WNV:


  • Drain standing water around their homes to reduce mosquito breeding grounds. Consider use of BTI briquettes (or mosquito dunks) in water that cannot be drained, such as small ponds and drinking troughs.
  • Be aware of mosquitoes during times that they are active, Dawn, Daytime, Dusk and evening hours.
  • Apply an insect repellent that contains DEET (N,N-diethyl-m-toluamide) to exposed skin and to clothing when outdoors. The Centers for Disease Control and Prevention (CDC) also recommends Picaridin (KBR 3023).
  • Dress in pants and long sleeves when outside and/or wear permethrin-treated clothing.
