Mosquito Trap Tests Positive for West Nile Virus in Granger
August 4, 2021 – A mosquito trap sample collected in the City of Granger has tested positive for West Nile virus. This testing is part of Williamson County and Cities Health District’s (WCCHD) Integrated Vector Management program. The positive test was indicated in lab results received on August 4th from the Texas Department of State Health Services lab in Austin.
The positive sample was taken from a trap site near N. Colorado St.. The last date a positive sample was collected was June 29, 2021.
This is the fourth reported West Nile virus positive trap of the 2021 season in Williamson County, and the third time this trap has tested positive this year.
Symptoms of infection may include fever, headache, and body aches, a skin rash on the trunk of the body, and swollen lymph nodes. Those age 50 and older and/or with compromised immune systems are at a higher risk for severe symptoms, which may include stiffness, disorientation, coma, tremors, vision loss, paralysis, and in rare cases, death.
The most important way to prevent West Nile virus is to reduce the number of mosquitoes where people work and play. Health officials strongly encourage everyone to remain vigilant about protecting themselves from mosquito bites and preventing mosquito breeding on their personal property. Mosquitoes breed in standing water, needing as little as one teaspoon. By draining all sources of standing water in and around your property, you reduce the number of places mosquitoes can lay their eggs and breed.
What you can do:
Eliminating places where mosquitoes can breed and reducing the chances of mosquito bites are the most effective lines of defense against exposure to West Nile Virus. As part of its Fight the Bite campaign the Health District recommends the 3 Ds of mosquito safety:
- Drain standing water in flowerpots, pet dishes, or clogged gutters so mosquitoes don’t have a place to breed and treat water that can’t be drained,
- Defend by using an EPA-registered insect repellent, and
- Dress in long sleeves and pants when outdoors.
