Tarrant County Public Health confirmed a West Nile Virus-positive mosquito sample, the first of the 2023 season, county officials announced in a news release Wednesday.
No human cases have been reported in 2023.
The positive sample was collected in Euless.
West Nile Virus season typically runs from April through mid-November, according to county officials.
Local cities and Tarrant County may perform mosquito treatment, as deemed appropriate.
So far, 369 mosquito samples have been tested at TCPH’s North Texas Regional Laboratory.
Last year, TCPH reported its first West Nile Virus-positive mosquito sample on May 11.
TCPH reminds residents to take measures to safeguard against the West Nile Virus. Residents should dump standing water on their property, use repellent, and — whenever possible — dress in long pants and long sleeves.
More information from Tarrant County Public Health about mosquitoes and West Nile Virus:
Mosquitoes need water to breed. They don’t lay their eggs in the air or on the ground, so it is advised to dump all standing water.
Infected mosquitoes transmit West Nile Virus to people after feeding on infected birds.
Birds do not transmit the virus to people.
Larvicides are products used to eliminate mosquitoes before they become adults. It is recommended to apply larvicides directly to water sources that hold mosquito larvae.
