INDIANAPOLIS (AP) — Central Indiana health officials are reporting the state’s second human case this year of West Nile virus.

The Health Department in Madison County northeast of Indianapolis reported the case Friday. The report comes three days after the Indiana State Department of Health said the first such case was reported in Huntington County, southwest of Fort Wayne.

No other details about the patients have been released.

The state health department says mosquitoes in nearly 30 counties from the Michigan border to the Ohio River have tested positive for the virus this year.

It urges Hoosier to avoid the outdoors when mosquitoes are active from late afternoon to dawn, using insect repellent on exposed skin, and installing or repairing screens on windows and doors to keep mosquitoes out of the home.
