The Collin County Health Care Services Department is reporting that as of Monday, July 30, there have been eight confirmed West Nile Virus cases in Collin County, according to the county's website.

Collin County recommends residents protect themselves by using the following "Four Ds," noting that six of the eight residents who contracted the virus reported to the county's health department that they did not use insecticide.

  • Apply insect repellent that contains DEET (N, N-diethyl-m-toluamide). Be sure to read label instructions. Spray clothing with repellent as well as exposed skin.
  • Dress in long sleeves and long pants when you are outside.
  • Stay indoors at dusk and dawn, times when infected mosquitoes are most active.
  • Drain standing water in your backyard and neighborhood; old tires, flowerpots and clogged rain gutters are mosquito-breeding sites.
  • Residents should continue to follow these recommendations until the first freeze this fall.

Symptoms of West Nile Virus

People who develop symptoms from West Nile Virus may have fever, headache, body aches, swollen lymph glands, tiredness, and may notice a skin rash on the trunk of the body, according to the Collin County Health Department.

Symptoms can last just a few days or a person may be ill for several weeks. Anyone who is experiencing these symptoms is advised to contact their health care provider.

In some individuals, symptoms are severe and they may experience neck stiffness, high fever, headache, muscle weakness, disorientation, tremors, convulsions, paralysis and coma. 

People over 50 years of age and those who have weakened immune systems have the greatest risk of becoming severely ill if they are infected with West Nile Virus.

County health officials say that mosquitoes will continue to pose a risk until the temperature drops below 50 degrees consistently at night.

Residents are asked to report standing water, illegal dumping and increased mosquito activity. Please visit the county's Report a West Nile Virus Concern page for more information.
