2019 Michigan Measles Outbreak Information

As of May 17, 2019, the Michigan Department of Health and Human Services has confirmed 44 total measles cases statewide since March 13, 2019.

The outbreak, which began in mid-March, has resulted in 40 cases in Oakland County, one in Wayne County and one in the City of Detroit.

In addition, an international traveler was diagnosed with measles following a visit to Washtenaw County and a second international traveler resulted in a case of measles in St. Clair County in May. Infected individuals range in age from 8 months to 63 years; a majority of the cases involve adults.

Unvaccinated residents, or residents who are unsure of their vaccination status, should get vaccinated. Residents should contact their healthcare provider or local health department to receive vaccine. If symptoms develop, do not visit your doctor or emergency room unless you call ahead so they can take precautions to prevent exposure to other individuals.

The measles vaccine is highly effective and very safe. A single dose of measles vaccine protects about 95 percent of children, but after two doses, almost 100 percent are immune. You cannot get measles from the vaccine. It can be effective within 72 hours of exposure to prevent illness. More information on the measles vaccine is available in the fact sheets:

In addition, immune globulin treatment is effective within six days of exposure for high-risk individuals. Talk to your healthcare provider to determine if immune globulin is right for you and if it is available. High-risk individuals include those who are unvaccinated or unsure about vaccination status, pregnant women and those who are immune-compromised (have a weakened immune system due to illness and diseases like HIV, malnutrition and/or medications).

Healthcare Provider Information

Persons who work in health care settings are at increased risk of exposure to measles and at increased risk of transmission to persons at high risk of severe measles. All persons who work in such settings and have the potential for exposure to potentially infectious patients or materials should have presumptive evidence of immunity to measles to prevent any potential outbreak.
