State health officials have confirmed 113 cases of a new strain of swine flu in 18 Indiana counties and expect to confirm more cases later this week.
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.
