OKLAHOMA CITY (AP) — The Oklahoma State Department of Health has only confirmed one human case of West Nile virus this year, a huge drop from two years ago.
The Oklahoman reports that 2012 was the worst year on record for the mosquito-borne disease, with 176 cases and 15 deaths. There were 84 confirmed cases last year, including eight people who died.
State epidemiologist Kristy Bradley says this year's West Nile season illustrates how cyclical the virus can be.
Oklahoma's only case of West Nile this year was confirmed in early July in a Major County resident. The West Nile season usually runs from July to October.
