Recent Measles Cases in Massachusetts
Health officials have confirmed that two recent cases of measles in Massachusetts are unrelated. This marks the first instance of measles among state residents since 2024.
The Department of Public Health was made aware of a child’s infection on Wednesday. Preliminary reports indicate that the child may not have been vaccinated, although officials are working to verify this information.
On Thursday, lab results identified an adult case, prompting health officials to quickly trace the individual’s whereabouts and potential contacts. Dr. Catherine Brown, the state epidemiologist, mentioned that the recent blizzard might have helped limit the virus’s spread, as the infected person sought medical attention during the heavy snowfall, when facilities were less crowded.
Dr. Brown described the infected adult as being “extraordinarily forthcoming,” adding that they are currently isolating safely. “In this case, we consider ourselves rather fortunate,” she stated, noting they are aware of the individual’s activities while they were contagious.
Health care facilities have begun notifying those who might have been exposed and are assessing their risk levels. Most of these individuals have vaccination records, as Massachusetts boasts a high vaccination rate against measles. As such, Dr. Brown believes the situation shouldn’t be too alarming for them.
The specific health care facilities have not been named, but officials assure that anyone who was potentially exposed has been contacted.
According to state representatives, the infected adult recently returned from a country where measles is prevalent. It’s been clarified that the individual began experiencing symptoms only after their flight, ruling out any possibility of them infecting fellow passengers.
Both patients are now recovering. Measles is recognized as one of the most contagious viruses globally. The CDC reports that it can infect up to 90 percent of unvaccinated individuals exposed. Dr. Vandana Madhavan, an infectious disease expert, emphasizes that the virus can remain airborne for hours, making it difficult to prevent further cases.
Despite measles becoming rare in the U.S., a national resurgence is noted, largely attributed to declining vaccination rates. Last year saw 2,281 cases, the highest figure since 1992, with three fatalities reported.
Recent outbreaks have been documented in Texas and South Carolina. Currently, 1,136 cases have been identified in the U.S. since January, suggesting a steep rise in infections compared to the previous year.
In New England, Maine has reported five cases this year, while Vermont has recorded one.
Measles symptoms can take up to two weeks to show. Initially, they mimic cold-like symptoms, including coughing, a runny nose, and fever. A rash usually appears within a few days. Those infected are contagious from four days before the rash appears to four days after.
Historically, measles was a common childhood illness, though it can result in severe complications, especially for children under five. Around 30 percent may experience serious health issues like pneumonia or brain inflammation.
The American Academy of Pediatrics recommends children receive their first dose of the MMR vaccine—protecting against measles, mumps, and rubella—around their first birthday, with a second dose between ages four and six, leaving many young children vulnerable.
Currently, more than 96 percent of Massachusetts kindergarteners are vaccinated against measles, based on data for the 2024-25 school year. However, some regions, particularly in western Massachusetts and Cape Cod, show lower vaccination rates.
A recent study from Boston Children’s Hospital highlighted the risk of measles outbreaks among children under five, pinpointing certain areas of Greater Boston as “high” risk. Dr. Benjamin Rader from the hospital remarked on the likelihood of additional cases emerging in Massachusetts, suggesting these instances signal that the problem may persist.
