OKLAHOMA CITY (AP) -- An elderly Oklahoma County woman has died after being infected by the West Nile virus, the first Oklahoman to die from the mosquito-borne disease this year.
State Health Department officials said Thursday that the West Nile victim was between 70 and 79 years old. She was among four cases of the virus that have been recorded so far in 2013.
The state's epidemiologist, Dr. Kristy Bradley, says all four recorded cases have been in Oklahoma County. But Bradley says Health Department surveillance equipment has detected infected mosquitoes in Tulsa and Comanche counties.
Bradley says parts of the state are reaching the peak period for West Nile transmission. She says hot and dry weather is conducive to the spread of the disease.
Fifteen Oklahomans died from the disease last year.
