After a mosquito in Cedar Park tested positive for West Nile Virus in mid-July, city officials have been working with the Williamson County and Cities Health District to collect additional samples from 10 mosquito trap locations throughout the city. All subsequent tests for the virus have been negative, the city reported on Aug. 1. The positive sample was collected from a location in northwest Cedar Park in the area near Veteran’s Park, City Manager Brenda Eivens said. The positive test was indicated in a lab result from the Texas Department of State Health Services in Austin. Eivens said the city placed signs in the Veteran’s Park area to let users know about the positive sample, and residents will see yard signs and additional social media coverage reminding people of the WCCHD’s campaign to prevent mosquito bites. There are no reported human cases of the virus in Cedar Park, and Williamson County has not seen a reported case since 2014, according to the city. In Frisco, 13 pools tested positive for West Nile virus this year, and the city hired a contractor to conduct ground spraying in July. Routine mosquito trapping will continue as usual, according to the health district’s Best Practices for Integrated Mosquito Management. During a special called meeting July 21, the Cedar Park City Council approved a resolution that would allow the city manager’s office to execute an agreement with the WCCHD for mosquito spraying. The agreement would authorize preventative spraying measures for the control and eradication of mosquitoes in Cedar Park.
