OKLAHOMA CITY — The Oklahoma State Department of Health has reported two more cases of the potentially fatal West Nile virus.
Health officials on Thursday say Oklahomans in Custer and Carter counties contracted the mosquito-borne virus, bringing the total number of infections this year to six. No one has died.
A mosquito tested positive in Oklahoma County last week but no human infections have been recorded there this season.
There were 84 cases of West Nile virus in Oklahoma last year and eight deaths. There were 176 cases and 15 deaths in 2012.
The virus is spread by the Culex mosquito, which feeds on infected birds. It transmits the virus when biting humans, horses and other mammals. Symptoms include a sudden fever, headache, dizziness and muscle weakness.
