Officials warn of possible measles exposure at Montgomery County urgent care

Health officials in Montgomery County have issued a warning to residents after a person with measles visited an urgent care in Collegeville while contagious.

Officials said the individual with measles was at Patient First Primary and Urgent Care-Collegeville on January 29, 2026, between 1:15 p.m. and 4:15 p.m.

Anyone who was at that urgent care on that date may have been exposed.

If you believe you were exposed, officials urge that you monitor yourself for symptoms. Measles can remain airborne and on surfaces for up to two hours even after an infected person leaves.

The Montgomery County Department of Health and Human Services Office of Public Health shared a list of what to do if you think that you may have been exposed:

• Check your vaccination records. Individuals are usually protected from measles if: You were born in 1957 or earlier, or you have had 2 doses of Measles, Mumps, Rubella (MMR) vaccine, or the recommended vaccine doses based on your age. Laboratory testing confirming of disease or immunity.

• If you are not fully vaccinated or protected and think you might have been exposed, call your health care provider, urgent care, or hospital before you visit. This helps protect staff and other patients.

• Watch for symptoms for 21 days after exposure, including fever, an unexplained rash, cough, congestion or runny nose, or red watery eyes (conjunctivitis).

• If you develop symptoms, stay home and call a health care provider right away.

Officials said infants and children less than 5 years old, pregnant women, and people with weakened immune systems are most at risk for complications.

Measles can be prevented with two doses of the MMR vaccine.
