Mumps Confirmed In Oakland County, 9th MI Case Of 2025: Officials

OAKLAND COUNTY, MI — Oakland County health officials confirmed on Friday the county's first mumps case of 2025.

Health officials said the case was found in an adult. Officials said no close contacts or exposures have been identified with the case.

It is Oakland County's first case since 2022 and the ninth mumps case in Michigan in 2025, according to county health officials.

"This case of mumps, coming just weeks after Oakland County's first measles case of the year, underscores the essential role of vaccination in protecting our communities," Oakland County Health Officer Kate Guzmán. "The MMR vaccine remains our best defense against measles, mumps and rubella, offering highly effective protection against these serious diseases and helping to prevent outbreaks."

Mumps is a contagious viral infection that affects the salivary glands. It spreads through direct contact with saliva or respiratory droplets from the mouth, nose or throat. Symptoms typically appear 16 to 18 days after exposure and may include:

• Fever
• Headache
• Muscle aches or pain
• Loss of appetite
• Fatigue
• Swelling on one or both sides of the face (chipmunk cheeks)
• Jaw pain or swelling
• Pain or tenderness around the swelling

Most people with mumps recover within two weeks, but serious complications can occur, including hearing loss and inflammation of the testicles, ovaries, breast tissue, pancreas, brain and tissue covering the brain and spinal cord.

There is no treatment for mumps - only management of symptoms – making the Measles, Mumps, and Rubella (MMR) two-dose vaccine the best form of protection.

Health officials recommend that children receive their first dose at 12 to 15 months and a second dose at 4 to 6 years old, or at least four weeks after the first dose.

If you have not received a second dose or if you are unsure of your vaccination status, officials encourage you to contact your healthcare provider.
