The Oklahoma City-County Health Department has confirmed a human case of West Nile Virus (WNV) in Oklahoma County.
County health officials said there has also been a positive test this week for the presence of the virus in the local mosquito population. This is the second positive test this year.
In May the Tulsa City-County Health Department said they had detected one positive test for WNV from sampling of mosquitoes, but no human cases.
Typically, the months of July through October are the highest risk months for exposure to West Nile in Oklahoma, but the department begins its mosquito surveillance program in May.
