MARQUETTE, Mich. (AP) -

Some Michigan hospitals are restricting visitors due to a rise in influenza cases.

Marquette General Hospital has implemented such restrictions until further notice. The medical center says it's doing so as a precaution to protect patients and staff from the spread of the flu.

The Mining Journal says that at Marquette General Hospital, only essential family visitors are permitted to come to patient rooms, children under the age of 14 aren't being allowed into the hospital unless for a medical appointment or an emergency room visit and visitors in the Family Birthing Center are limited to parents and grandparents.

In Kalamazoo, Borgess Medical Center on Friday also began restricting who can visit patients.

According to the Kalamazoo Gazette, Borgess visitors must be 12 or older unless they're a patient's sibling.
