The State Department of Health said Wednesday the number of confirmed human cases had leapt from just 11 in Indiana last week and only 29 nationwide, including at least 12 in neighboring Ohio.
The counties with confirmed cases stretch from northwestern Indiana through the center of Indiana to south-central Indiana. All of the cases were transmitted to humans by sick hogs.
The Indiana State Fair sent home most of the hogs in its swine barn Monday after six pigs in the 4-H show developed high fevers.
State Health Commissioner Gregory says the flu is a mild illness with symptoms similar to seasonal flu.
To avoid influenza and other respiratory infections, Hoosiers are reminded to follow these simple practices:
Wash your hands frequently, including before and after touching animals.
Never eat, drink, or put anything in your mouth when visiting animal areas.
Older adults, pregnant women, young children, and people with weakened immune systems should be extra careful around animals.
Cough or sneeze into your sleeve or elbow.
If possible, avoid contact with those who are ill.
Stay home if you develop influenza symptoms and contact your health care provider.
