Cedar Park: Mosquito lure checks constructive for West Nile Virus pattern collected Nov. 19 close to Solar Chase and Lakeline.


November 24, 2020

A mosquito trap sample collected in the City of Cedar Park tested positive for the West Nile virus. These tests are part of the Williamson County and Cities Health District (WCCHD) integrated vector management program. The positive test was indicated in laboratory results obtained November 24th from the Texas Department of Health Laboratory in Austin.

The positive sample was obtained on November 19 from a trap site near Sun Chase Boulevard and Cypress Creek Road. This is the first positive test result from this location this year. On the final day on November 4th, a positive sample was taken from the area near the HEB center.

In 2020, there were 17 mosquito trap samples found positive for West Nile Virus in other parts of Williamson County – the highest ever recorded since the program began in 2012. Three cases of West Nile virus in humans were reported in Williamson County that year.

Symptoms of infection can include fever, headache and body aches, rash on the trunk of the body, and swollen lymph nodes. People aged 50 and over and / or with compromised immune systems are at greater risk of severe symptoms, including stiffness, disorientation, coma, tremors, loss of vision, paralysis and, in rare cases, death.

Central Texas has mosquitos year round, but the population is largest and most active from May to November. During this time, WCCHD monitors the mosquito population and tests for mosquito-borne viruses.

“Cooler temperatures extend moist breeding areas for mosquitoes,” said Jason Fritz, program director for integrated vector management at WCCHD. “It is highly recommended that you drain standing water in your home outdoors, especially at dusk and dawn, and use insect repellant to protect yourself and your family from mosquito-borne diseases.”

The most important way to prevent West Nile virus is to reduce the number of mosquitos that people work and play in. Health officials strongly encourage everyone to remain vigilant to protect themselves from mosquito bites and prevent mosquito growth on their personal property. Mosquitoes breed in standing water and only need a teaspoon. By draining any standing water sources in and around your property, you will reduce the number of spots where mosquitoes can lay and breed their eggs.

What you can do:

Eliminating places where mosquitoes can breed and reducing the likelihood 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 protection:

  • Drain standing water in flower pots, animal dishes, or clogged gutters so that mosquitoes have no place to grow and treat water that cannot be drained.
  • Defend using an EPA approved insect repellent and
  • dress outdoors in long sleeves and pants.
