A dead crow found in the Harden Street area of Columbia last week has tested positive for West Nile virus, according to Richland County Council member Seth Rose.

This is the time of year for West Nile to crop up. The infected bird in Columbia is one of four cases reported so far this year by the S.C. Department of Health and Environmental Control. The others were an infected horse in York County, infected mosquitoes from a pool in Beaufort County and a human infection in Charleston County.

West Nile, which is spread by mosquitoes, has been reported in the state every year since 2002. Most people infected with West Nile don’t get sick, but some people come down with flu-like symptoms and a few people suffer life-threatening inflammation of the brain or spinal cord.
