Michigan health officials said Friday they have found no connection between confirmed or probable mumps cases here with a large outbreak in Iowa.
But other cases of suspected mumps in Michigan still are under investigation, including possible connections to the larger Midwest outbreak, a spokesman for the state Department of Community Health said Friday.
Michigan health officials this year have confirmed three cases of mumps, e each in Oakland, Saginaw and Delta counties.
Four probable cases of mumps have been reported in Bay, Oakland, Marquette and Saginaw counties.
The state is investigating another 13 potential mumps cases, said T.J. Bucholz, a spokesman for the Department of Community Health.
Twenty-three cases of mumps were reported in Michigan in 2005.
One of the largest mumps outbreaks in the past 20 years is centered in Iowa, where the number of cases for this year is approaching 1,000.
Mumps is spread by coughing and sneezing. The most common symptoms are fever, headache and swollen salivary glands under the jaw. But it can lead to more severe problems, such as hearing loss and meningitis.
