Tulsa Health Officials Confirm Two Cases of West Nile in County

Tulsa health officials have confirmed Thursday morning two cases of West Nile Virus in Tulsa County.

According to a release from the Tulsa Health Department these are the first confirmed human cases reported in Tulsa County this season.

"Residents are urged to continue to take precaution against WNV as months with the highest risk for exposure to WNV are the months of July through October," the release went on to state.

Health officials warn that anyone in an area where WNV is confirmed is at risk for exposure. But they also added that approximately 80 percent of individuals infected will have no symptoms.


West Nile virus is spread through the bite of an infected mosquito, which feeds on infected birds and then transmits the virus when biting humans, horses, and some other mammals, according to a fact sheet. Symptoms of WNV include sudden onset of fever, headache, dizziness, and muscle weakness.

In addition to the above symptoms those affected by WNV can also experience long-lasting complications which can include difficulty concentrating, migraine headaches, extreme muscle weakness and tremors and paralysis of a limb.

Helpful Precautions to Take Against Mosquito Bites

Use an insect repellent containing DEET on exposed skin and clothing when you go outdoors, particularly if you are outside between dusk and dawn when mosquitoes are more likely to bite. (Insect repellent with permethrin should be used on clothing only.)

Repair or install window and door screens to keep mosquitoes out of your home.

Prevent items such as buckets, cans, pool covers, flower pots, and tires from holding standing water so mosquitoes don't have a place to breed.

Empty your pet's outdoor water bowl and refill daily.

Clean leaves and debris from rain gutters regularly to ensure they are not clogged.
