Michigan has 115 swine flu cases

State health officials announced Saturday that Michigan has 115 confirmed cases of swine flu. That includes 11 new cases.

The state began confirming its own cases Thursday, James McCurtis, spokesman for the Michigan Department of Community Health, said earlier in the week.

The cases are spread among 20 counties. Kent County, home to Grand Rapids on the west side of the state, has the most confirmed cases of any county, at 45. Macomb County has 13 confirmed cases; Livingston, eight; Wayne, three; Oakland, four and Washtenaw, nine.

Officials confirmed one case at Brother Rice High School in Bloomfield Township. In a letter to parents Thursday, school officials said a student had a fever last weekend but "felt fine" Monday and was in school Wednesday before health authorities confirmed the case was H1N1. The CDC has determined the H1N1 virus is similar to seasonal flu and not as severe as feared.

The state is no longer reporting the number of probable cases.
