A sampling of mosquitoes taken at a trap near the Southwest Williamson County Regional Park tested positive for West Nile virus for the third week in a row, according to a July 27 news release.

The Williamson County and Cities Health District reports that the positive results were found near New Hope Drive and CR 175. The district also set up two traps in expanded locations that have tested negative for the virus, the release said.

Williamson County will adjust hours for park visitors at the Southwest Williamson County Regional Park to prevent exposure to mosquitoes when they are most active, the release said. Starting July 28, the park will be open from 7:30 a.m.-8 p.m., it said.

Health officials strongly encourage everyone to remain vigilant about protecting themselves from mosquito bites and preventing mosquito breeding on their personal property by removing any standing water.

Williamson County parks staff will continue mosquito control efforts with draining or treating standing water with larvicide, it said.


There have been no reported human cases of West Nile virus in Williamson County since 2017, the release said. The Texas Department of State Health Services reported the first human case of West Nile virus this year on July 23 in an adult in Tarrant County who later died, it said.
