INGHAM COUNTY, Mich. – Health officials have confirmed a second case of measles in Ingham County.
The county’s second case of measles this year was confirmed in a one-year-old boy who was exposed to the first case, in which the virus was confirmed in a one-year-old girl after she traveled out of the state. The first case was confirmed on April 15.
Health officials say the boy was “age-appropriately vaccinated” and experienced mild symptoms.
“Due to early isolation and limited exposure, the risk to the broader community remains low,” the Ingham County Health Department said in a release.
After the possible exposure to the first case, communicable disease nurses from the county’s health department contacted the boy’s family to ensure they were monitoring for symptoms.
The boy was tested after symptoms appeared, and measles was confirmed on April 22.
“We understand that news of another case may cause concern in our community,” said Ingham County Medical Health Officer Dr. Nike Shoyinka. “However, this child’s vaccination status helped lessen the severity of illness, and early isolation significantly reduced the risk of transmission. This case highlights the importance of timely vaccinations and swift public health response.”
The potential exposure site connected with this case is the Lansing Urgent Care at 505 North Clippert Street in Lansing, with the possible exposure window from 6:30 p.m. to 9:00 p.m. on April 15.

- Cough
- Runny nose
- Red, watery eyes (conjunctivitis)
- Tiny white spots on the inner cheeks, gums and roof of the mouth (Koplik Spots)
A rash that starts as flat red spots on the face at the hairline, then spreads to the trunk, arms and legs three to five days after the symptoms begin. Small, raised bumps may also appear on top of the flat red spots.

Measles vaccine
Health officials say getting the measles, mumps, and rubella (MMR) vaccine is the best way for residents to protect themselves against measles.
According to the CDC, two doses of the measles vaccine are about 97% effective at preventing measles if exposed to the virus. One dose of the vaccine is believed to be about 93% effective. You are considered fully protected about two to three weeks after getting the vaccine.
