TULSA, Okla. (AP) — Tulsa Health Department officials say a sampling of mosquitoes from Tulsa County has tested positive for the potentially deadly West Nile virus.
The department operates a mosquito surveillance program and mosquito traps are set in various locations throughout the county. Samples are collected and tested weekly for the virus and areas are sprayed in an effort to control the mosquito population.
Health officials say there have been no human cases of West Nile virus in Tulsa County this year. The only confirmed case of the virus in Oklahoma thus far this year has been in Major County.
There were 84 cases last year — including eight deaths.
The virus is spread through the bite of an infected mosquito. Symptoms include a sudden onset of fever, headache, dizziness, and muscle weakness.
