Three people in Allen have contracted West Nile virus, according to Collin County Health Care Services.
The city did not say in which zip codes the infected people reside.
CCHC said they plan to continue treating mosquitoes with larvicide in stagnant swimming pools and selected creeks and detention ponds. To date, CCHC said 24 stagnant swimming pools have been treated and over 20 public areas have been inspected and treated.
“We encourage residents to be vigilant in eliminating all outdoor sources of standing water and to take safety precautions when outside early morning and at dusk when mosquitos are most active," said Lee Battle, assistant director of community development in Collin County.
Citizens can report areas of stagnant water to code enforcement by calling 214-509-4160.
Information regarding West Nile Virus and mosquito control precautions is available on the Collin County Health Care Services web page.
