Public health officials in Massachusetts said Wednesday that a person who visited the state from out of town may have exposed people to measles.

The state Department of Public Health said the visitor arrived at Logan International Airport on Dec. 11 on American Airlines flight 2384 from Dallas-Fort Worth.

The person stayed at the DoubleTree by Hilton Hotel Boston-Westborough in Westborough.

The person left Massachusetts on Dec. 12 from Logan Airport on JetBlue flight 117 to Las Vegas.

The DPH said it’s working with the Centers for Disease Control and Prevention and others to identify and notify the people who may have been exposed to measles.

“Measles is a highly contagious, airborne disease, which has increased significantly in the United States because of the unfortunate decrease in vaccination rates. It is also a preventable disease,” said Public Health Commissioner Robbie Goldstein, M.D., Ph.D, in a statement.

The department said anyone who’s not immune and visited the following locations at these specific dates and times may be at risk:

  • Logan Airport Terminal B, Boston, 2:30 p.m. to 4:45 p.m., Dec. 11.
  • DoubleTree by Hilton Hotel Boston-Westborough, Westborough, between 3:30 p.m. Dec. 11 and 9 p.m. Dec. 12
  • Logan Airport Terminal C, Boston, 6 p.m. to 11:30 p.m., Dec. 12

Health officials said anyone who might have been exposed and develops symptoms should call their health care provider first before going to the doctor’s office, an urgent care or the hospital.

“Visiting a healthcare facility may put others at risk and should be avoided if possible,” the DPH said.

Health officials said early symptoms of measles appear seven to 21 days after exposure and may resemble a cold. A rash occurs on the skin two to four days after the initial symptoms develop.

They said the rash usually appears first on the head, moving down the body. The rash typically lasts a few days and then disappears.

The DPH said Massachusetts had no reported cases of measles in 2025.

“The risk to most people in Massachusetts is low because the vaccination rate in the state is high,” the statement said.

The department said anyone who has had measles or has received two doses of the measles, mumps and rubella vaccine — also called MMR — is unlikely to develop measles even if exposed.

Health care providers who suspect measles should call the Department of Public Health at 617-983-6800 for recommendations and testing guidance
