Ohio Blood Samples to be Tested for West Nile

The Ohio Department of Agriculture and the U.S. Department of Agriculture have collected 143 blood samples from horses in Lake County, Ohio, to determine if the horses have been exposed to West Nile virus. The first confirmed incidence of the virus in a bird was found in that area.

The blood samples will be tested by the Ohio Department of Health in Columbus. The results are due by mid-August.

"This is simply a precautionary measure to determine if any of the horses in the area have been exposed to the virus," said Fred Dailey, director of the Ohio Department of Agriculture.

The infected blue jay was the first positive indicator the virus had officially arrived in the state, officials said. Lake County is located along the Lake Erie shore in northeast Ohio not far from the Cleveland metropolitan area.
