CDC Reports Case of West Nile Virus in Knox County

Posted on June 10, 2025

Knoxville, TN (WOKI) The Centers for Disease Control and Prevention (CDC) is reporting three human cases of West Nile Virus in Tennessee, including one in Knox County.

So far in 2025, the CDC is reporting 10 cases across the U.S.; nearly a third of those are in Tennessee, which also has the most cases of all the states listed.

The other two cases are being reported out of Carroll County and Shelby County.

According to the CDC, West Nile Virus is the leading mosquito bite-caused disease in North America, though only about one in five people who are infected see symptoms, and only one in about 150 people develop a serious illness.

There are plenty of ways to prevent West Nile Virus, which is primarily spread through mosquito bites. The CDC lists these recommendations:

  • Use insect repellent
  • Wear long-sleeved shirts and pants outside
  • Treat clothing and outdoor gear
  • Take steps to control mosquitoes indoors and outdoors
