A person in Ripley County has West Nile Virus, a disease contracted through contact with mosquitos.
Officials have identified West Nile in 30 counties around the state.
Mosquito populations are much larger than normal because of the mild winter and warm spring.
The health department is urging property owners to insure that there is no standing water on their property, as stagnant water leads to mosquitoes.
The extreme temperatures of the last ten days may doom some of Indiana‘s mosquito population.
"It doesn't take them a lot of time," says one state health representative, "to get from eggs to hatching."
