The Oklahoma State Department of Health is reporting the first three human cases of West Nile Virus for the season. The cases have been confirmed in residents of Canadian, Grant and Tulsa counties.
Summertime typically marks the beginning of the West Nile Virus season in Oklahoma, with outdoor activities providing opportunities for encountering infected mosquitoes. Health officials are reminding the public to take precautions to prevent getting bitten by an infected mosquito.
West Nile Virus is spread through the bite of the Culex mosquito, which feeds on infected birds and transmits the virus when biting humans, horses and some other mammals. This type of mosquito increases in numbers during mid to late summer when the temperatures climb and the weather pattern is dry. Health officials expect the number of cases to increase as the temperatures rise throughout the summer.
