First cases of human West Nile confirmed in Central Indiana

The first cases of human West Nile virus have been confirmed in Hamilton and Marion counties.

According to the Indiana State Department of Health, the two human cases have been confirmed. In addition, mosquito groups in 44 counties have tested positive for the virus.

Those counties are: Adams, Allen, Bartholomew, Benton, Blackford, Boone, Clay, Daviess, DeKalb, Delaware, Dubois, Elkhart, Fayette, Hamilton, Hendricks, Henry, Huntington, Jefferson, Jennings, Johnson, Knox, Lake, Marion, Martin, Miami, Montgomery, Morgan, Noble, Orange, Owen, Parke, Putnam, Randolph, Ripley, Shelby, Sullivan, Tippecanoe, Tipton, Vanderburgh, Vermillion, Vigo, Wayne, Wells and Whitley. 

“Unfortunately, these two cases tell everyone that despite the dry conditions and hot temperatures, the virus is circulating in the state and we’re susceptible to infection,” said State Health Commissioner Gregory Larkin, M.D. “Usually the virus causes only mild disease, but some people will develop more severe illness. Hoosiers should take steps to protect themselves from being bitten by mosquitoes.”

State health officials recommend that Hoosiers apply insect repellent containing DEET, repair broken windows or screen and wear pants and long sleeves when possible.

According to the health department, West Nile virus usually causes West Nile fever, a milder form of the illness. Symptoms include:


  • Fever
  • Headache
  • Body aches
  • Swollen lymph glands
  • Rash
