LANSING, MI – The number of cases in a measles outbreak centered in Southeast Michigan continues to rise, with state health officials saying today the number of infected patients in Michigan has risen to 41.

There have been two new cases reported since late last week. Among those, Washtenaw County now has its first case of the disease. And a new case in Oakland County brings that area’s total to 39. One case was earlier reported in Wayne County.

The patients range in age from an 8-month-old baby to a 63-year-old, according to the Michigan Department of Health and Human Services.

Measles is a highly-contagious disease which is spread through the air and by person-to-person contact.

“MDHHS is working closely with the Oakland County Health Division and Washtenaw County Health Department to identify possible exposure locations for these latest cases,” state health officials said.
