The third human case of West Nile virus this year in Denton County is an individual living in Trophy Club, Denton County Public Health said Thursday.

It's the second Denton County human case reported in the past two days.

On Wednesday, the city of Denton also raised its mosquito surveillance and response plan risk level to "Risk Level 5," the highest risk level.

DCPH recommended the following steps to minimize the risk of contracting West Nile virus: draining standing water, dressing in long sleeves and pants while outside and defending yourself using repellent.


  • Dress in long sleeves, pants when outside: For extra protection, spray thin clothing with repellent.
  • DEET: Make sure this ingredient is in your insect repellent.
  • Drain standing water in your yard and neighborhood: Mosquitoes can develop in any water stagnant for more than three days.

It has been recommended in the past that to avoid mosquito bites you should avoid being outdoors during Dusk and Dawn (the 4 Ds). While this is true for mosquitoes that commonly carry the West Nile virus, other types of mosquitoes that are more likely to carry Zika, dengue and chikungunya are active during the day. When outdoors, no matter what time of day, adjust your dress accordingly and wear insect repellent containing DEET, picaridin or oil of lemon eucalyptus as your first line of defense against insect bites
