APH said in a media release July 16 the mosquitoes were identified in ZIP code 78756, which is located in North Central Austin near Burnet Road and the Brentwood neighborhood.
No mosquitoes tested positive for the virus in Travis County in 2019, APH said in the release, but there were 119 positive pools across the state of Texas.
According to the Centers of Disease Control and Prevention, about 80% of people who are infected with the West Nile Virus do not feel symptoms. However, about 1 in 5 people develop a fever, and 1 in 150 people develop a severe illness.
On July 9, mosquitoes collected in a trap near the Southwest Williamson County Regional Park tested positive, according to a media release from Williamson County Cities and Health District, and WCCHD said July 16 that mosquitoes caught in two additional traps in the same area also tested positive.
APH said in its July 16 release that the best way to prevent the virus is for property owners to drain as much standing water as possible, reducing the number of places mosquitoes can lay their eggs and breed.
