A pool of mosquitoes has tested positive for the West Nile virus in a wooded area of a southwest Ohio park.
A spokesman for Public Health-Dayton & Montgomery County says the recent test of mosquitoes in a wooded area at Dayton's Wegerzyn Gardens MetroPark was the first positive one in the region this season. Public Health planned to treat the area with insecticide.
The Dayton Daily News reports that Franklin County also had a mosquito pool test positive this summer in the Columbus area.
There were 121 reported cases of West Nile virus in Ohio in 2012, including seven deaths. State health officials say no human cases have been reported so far this year in Ohio.
The virus can cause convulsions, paralysis and loss of vision in severe cases.
