Logan Airport Measles Alert

Massachusetts health officials are warning Logan Airport travelers after a person with measles passed through Terminal C on April 14. (boston.gov) The traveler arrived on JetBlue Airways Flight 470 from Fort Lauderdale, leaving Florida at 8:54 p.m. on April 13 and reaching Boston shortly after midnight, according to the Boston Public Health Commission and the Massachusetts Department of Public Health. (boston.gov) Officials said anyone in Terminal C between 12 a.m. and 2:30 a.m. on April 14 may have been exposed. The person left Logan in a privately owned vehicle and then went out of state. (boston.gov) Measles spreads through the air when an infected person breathes, coughs, or sneezes, and the virus can remain in the air for up to two hours after that person leaves. Early symptoms usually begin 7 to 14 days after infection. (cdc.gov) Boston health officials told unvaccinated people who may have been exposed to contact a healthcare provider immediately, monitor for symptoms, and avoid public places such as work, school, childcare, and public transportation. (boston.gov) The main symptoms health officials listed were fever, cough, runny nose, red eyes, and a rash that starts on the face and spreads downward. The Boston Public Health Commission said people who develop symptoms should call ahead before going to a clinic or hospital so staff can prevent more exposures. (boston.gov) The agency said the measles, mumps, and rubella vaccine is “highly effective,” and the Centers for Disease Control and Prevention says one dose is 93% effective against measles and two doses are 97% effective. (boston.gov) (cdc.gov) The airport alert comes as measles activity remains elevated nationally. The Centers for Disease Control and Prevention said last week that 1,748 confirmed U.S. cases had been reported in 2026, with 19 new outbreaks and 94% of cases linked to outbreaks. (cdc.gov) For Logan travelers, the key date is April 14: officials are tracing contacts from that overnight window and urging anyone unvaccinated who was there to act quickly. (boston.gov)
