(WWJ) Another case of measles has been detected in Metro Detroit, and it's the first for this year in Macomb County.
According to the Macomb County Health Department, the case has been confirmed in an adult who recently visited Ontario, Canada — an area which has been dealing with an outbreak of the disease.
Health officials said they do not believe the infected Macomb County resident to have been out in the public during the time they were at their most contagious. As a result, there are no exposure sites to report in connection with this case at this time.
Health officials did not release any further details about the patient, including their city of residence or age.
This news from Macomb County Friday comes after two other Michigan cases were confirmed in Metro Detroit in recent weeks: one in each of Oakland County and Kent County.
In a news release announcing the Macomb County case, health officials urged everyone to make sure they are vaccinated.
“Measles is a highly contagious disease and spreads through the air when a person coughs, sneezes or talks,” said Andrew Cox, director/health officer of Macomb County Health and Community Services. “If you are not vaccinated for measles, get vaccinated as quickly as you can. It is important to make sure you protect yourself and loved ones from this vaccine-preventable disease.”
Cases are increasing across the U.S. and outbreaks are occurring nationally and globally. As of March 27, 2025, a total of 483 measles cases have been reported by 19 states (including Michigan).
Health officials say 90% of unvaccinated people who are exposed to measles will become infected. Infected individuals can spread measles before noticing symptoms, including four days before the rash appears. Symptoms of measles usually begin 7-14 days after exposure, but can appear up to 21 days after exposure and may include:
- High fever (may spike to over 104˚F)
- Cough
- Runny nose
- Red, watery eyes (conjunctivitis)
- Tiny white spots on the inner cheeks, gums and roof of the mouth (Koplik Spots) two to three days after symptoms begin
- A rash that is red, raised, blotchy; usually starts on face, spreads to trunk, arms and legs three to five days after symptoms begin
If symptoms develop, call your doctor, urgent care, or hospital before seeking treatment so steps can be taken to prevent exposure to other individuals.

The health department says the measles vaccine is highly effective, very safe and provides long-lasting protection. A single dose of measles vaccine is about 93% effective at preventing measles, while two doses are about 97% effective. It is also effective if used within 72 hours of measles exposure to prevent illness.
Vaccination is available from at your family doctor's office, pharmacies, and the Macomb County Health Department. Children eligible for the Vaccines for Children program may be able to get the vaccine from a provider enrolled in the program at no cost.
