Measles Updates
Updates on Measles in the State of Michigan
This dashboard is updated weekly on Thursdays.
A previously reported measles case in Ingham County was removed from the overall case total after additional testing confirmed the individual was not infected with measles virus. This individual developed general respiratory symptoms and tested positive for measles after a known exposure to a confirmed measles case. The individual was previously vaccinated with one dose of measles mumps and rubella (MMR) vaccine and the positive measles laboratory test was later determined to be due to detection of vaccine strain virus. The individual's respiratory symptoms were not caused by the vaccine and were likely due to an unrelated illness. The vaccine strain does not cause measles or spread from person to person.
