Health officials in Tulsa have confirmed a second human case of the potentially fatal West Nile virus in Oklahoma this year.
The Tulsa Health Department confirmed the case on Thursday. The first confirmed case was in July in Major County.
Few details about the persons infected have been released, other than the person infected in Major County is over the age of 50. A Tulsa County health official did not immediately return a phone call seeking further comment.
There were 84 cases of West Nile virus in Oklahoma last year, including eight deaths.
The virus is spread by the Culex mosquito, which feeds on infected birds and transmits the virus when biting humans, horses and other mammals. Symptoms include a sudden fever, headache, dizziness and muscle weakness.
