Denton County reports 17th and 18th West Nile Virus Human Cases

Post Date:10/17/2016 11:04 AM

Denton County Public Health (DCPH) is reporting the 17th and 18th human cases of West Nile Virus (WNV) for 2016. The 17th case, a resident of Carrollton, was diagnosed with West Nile Neuroinvasive Disease (WNND). The 18th case, also a resident of Carrollton, was diagnosed with West Nile Fever.

Chief Epidemiologist Juan Rodriguez reminds residents to reduce their risks of acquiring WNV.

“Individuals can continue to help prevent mosquito bites by draining standing water around their homes, dressing appropriately, and using DEET or other EPA-approved repellents,” Rodriguez said.

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.

The City of Carrollton takes each case of WNV illness very seriously, and because of that commitment, the Environmental Services Department has activated the necessary sampling and testing protocols. Based on the results of those tests, the City will assess the need for additional ground spraying.
