Measles Cases Confirmed in Maryland After Out-of-State Travel

Two cases of measles have been confirmed in Maryland residents from the Baltimore metro area who recently traveled out of state, the Maryland Department of Health announced Friday.

The cases add Maryland to the growing list of states dealing with measles infections in 2026, a year that has already seen a notable uptick in cases nationwide. Health officials said both individuals contracted the disease during their travels and are now isolating while the department conducts contact tracing to identify anyone who may have been exposed.

Measles is one of the most contagious diseases known to medicine. The virus can linger in the air for up to two hours after an infected person leaves a room, meaning that exposure can happen in airports, transit stations, and other public spaces without direct personal contact. The Maryland cases underscore how travel — both domestic and international — continues to be a primary vector for the disease's spread.

The Maryland Department of Health is urging residents to verify their vaccination status. The measles-mumps-rubella (MMR) vaccine is highly effective — two doses provide approximately 97% protection — but vaccination rates have slipped in some communities in recent years, creating pockets of vulnerability where outbreaks can take hold.

Health officials are particularly concerned about potential exposure sites in the Baltimore metro area. Anyone who was in the same locations as the infected individuals during the infectious period is being asked to monitor for symptoms, which include high fever, cough, runny nose, red watery eyes, and the characteristic rash that typically appears several days after initial symptoms.

For most people who are vaccinated, the risk is minimal. But for infants too young to be vaccinated, immunocompromised individuals, and the small percentage of people for whom the vaccine doesn't produce full immunity, measles can be serious — and in rare cases, fatal.

What This Means For You: If you live in the Baltimore area and you or your children are not up to date on MMR vaccinations, now is the time to fix that. If you're unsure of your vaccination status, a simple blood test can confirm your immunity. And if you've recently traveled through airports or transit hubs in the region and develop a fever with a rash, contact your doctor immediately — don't just show up at a clinic, as measles is highly contagious and you'll need to be isolated.
