“The report of the first human case of West Nile virus in Williamson County this year is a stark reminder to the community of the need to take steps to avoid mosquito bites and to reduce mosquito populations,” said Dr. Lori Palazzo, WCCHD Medical Director and Williamson County Health Authority.



Symptoms of West Nile virus infection may include:

  • fever
  • headache
  • body aches
  • skin rash on the trunk of the body
  • swollen lymph nodes

Those age 50 and older and/or with compromised immune systems are at a higher risk for severe symptoms, which may include:

  • stiffness
  • disorientation
  • coma
  • tremors
  • vision loss
  • paralysis
  • in rare cases, death.

West Nile virus cannot be passed from human to human, says WCCHD, and infection occurs from a bite of an infected

WCCHD says it strongly encourages everyone to remain vigilant about protecting themselves from mosquito bites and to prevent mosquito breeding on their personal property. Mosquitoes breed in standing water, only needing as little as one teaspoon.

As part of its Fight the Bite campaign, the Health District recommends the 3 Ds of mosquito safety:

  • Drain standing water in flowerpots, pet dishes, or clogged gutters and treat water that can’t be drained
  • Defend by using an EPA-approved insect repellent
  • Dress in long sleeves and pants when outdoors
