Floyd County confirms human West Nile Virus case

FLOYD COUNTY, IN — Three mosquito traps in Floyd County have returned positive for the West Nile Virus, and a human case was identified, according to a release from the Floyd County Health Department.

The human case was diagnosed and treated in another state, and is recovering. It is unknown where in Floyd County the individual contracted the disease. The last human fatality in the county due to West Nile was in 2009.

On Thursday, the Clark County Health Department confirmed that three pools of mosquitoes infected with the West Nile Virus were detected during routine sampling in Jeffersonville and Sellersburg.

The West Nile Virus is spread by insects. Birds also serve as a vector. Most people infected by the virus have no symptoms; however, about 20  percent will develop a flu-like illness with fever, muscle aches, chills, headache, nausea, and occasionally rash. Less than 1 percent will have development serious neurologic disease, including meningoencephalitis. The incubation period is usually two to six days. The elderly and those with diabetes, cancer, and other diseases that affect the immune system are particularly at risk. Treatment is supportive only, and no vaccine is approved for use.

The primary way to lower risk is by lowering the number of mosquitoes to spread the disease. This can be done by homeowners checking their property for standing water that could serve as breeding grounds, and emptying those areas. Screens should be checked on windows and doors, and insect repellent should be used, especially during peak exposure hours near dawn and dusk.
