On Jun. 9, 2025, Oakland County Health Division in Michigan is notifying the public about a measles exposure site involving a person from another county. Individuals who visited the medical office building at 3950 S. Rochester Rd., in Rochester Hills, on the corner of Rochester Road and South Boulevard on June 3 may have been exposed to measles.

If you think you were exposed to measles at this location on June 3, Immune Globulin (IG) treatment is effective within six days of exposure for high-risk individuals. High-risk individuals include those who are pregnant, unvaccinated children under age 5 and those who have a weakened immune system due to illness and disease including diabetes or HIV, malnutrition and/or medications. If you are not eligible for IG, monitor symptoms through June 24. If symptoms develop, call ahead to your health care provider. Individuals born in or before 1957 are considered immune.

Measles is a highly contagious, vaccine-preventable disease that is spread by direct person-to-person contact and through the air. The Health Division recommends that unvaccinated individuals ages 1 year and older receive the measles vaccination to protect themselves and those around them. Anyone who doesn’t have a record of two MMR vaccines, unsure if they’ve have been vaccinated, or unsure if you’ve had measles in the past, needs to contact their health care provider.

Measles can live for up to two hours in the air where an infected person coughed or sneezed. Symptoms of measles usually begin 7-14 days after exposure, but can appear up to 21 days after exposure
