Health officials say the state's first human case of West Nile virus this year has been reported in southeastern Indiana and mosquitoes in nine counties have tested positive for the disease.
The Indiana State Department of Health said Wednesday that the case occurred in Ripley County, about 40 miles west of Cincinnati, Ohio. It provides no other details about it.
Adjacent Jefferson County, along the Ohio River, is one of the nine counties where mosquitoes have tested positive for the virus. Health officials say the others are Allen, Adams, Grant and Starke in northern Indiana; Vigo and Vermillion in the west; and central Indiana's Clinton and Hamilton counties.
Indiana had 77 West Nile cases last year. A severe form of the disease can cause encephalitis, meningitis, or muscle paralysis.
