Hays County Development Services (HCDS) received confirmation from the Texas Department of State Health Services (DSHS) on Nov. 6 that a mosquito trap sample collected in the 78676 ZIP code tested positive for West Nile Virus. The positive sample was collected from a site in the unincorporated area of Wimberley on Nov. 4.
This is the second reported West Nile Virus-positive mosquito trap of the 2025 season in Hays County. There were nine positive West Nile Virus mosquito traps during the 2024 season. In the state of Texas, DSHS reported 3,314 positive mosquito traps during the 2024 season for West Nile Virus. So far this year, DSHS has reported 1,243 positive mosquito traps for West Nile Virus.
Symptoms of West Nile Virus infection can include fever, headache, body aches, joint pain, vomiting, diarrhea, a skin rash on the torso of the body and swollen lymph nodes. While the risk for severe symptoms is low, individuals aged 50 and older and those with compromised immune systems may be at an increased risk. About 80% of people infected will have no symptoms.
Health officials strongly encourage everyone to remain vigilant about protecting themselves from mosquito bites and preventing mosquito breeding on their properties. Mosquitoes can breed in as little as one teaspoon of standing water.
“With a second trap in Hays County testing positive for West Nile Virus, it’s important for all of us to take simple steps to stay safe — use insect repellent, wear long sleeves when outdoors and empty any standing water around your home,” said Hays County Judge and Director of Emergency Services Ruben Becerra.
