MOUNT CLEMENS, Mich. -

Two more possible cases of MRSA are being investigated in the Mount Clemens School District.

Superintendent Deborah Wahlstrom told Local 4 the district is waiting to hear back from state health officials on whether the cases are in fact MRSA. But they come just a day after the district was shut down for crews to clean schools and buses after two staffers were diagnosed with the contagious bacterial infection.
