Logan Airport exposure alert

Travelers who passed through Boston Logan’s Terminal C early on April 14 may have been exposed to measles after an infected passenger arrived on a JetBlue flight from Fort Lauderdale. (wcvb.com) The Boston Public Health Commission said the passenger was in Terminal C between 12 a.m. and 2:30 a.m. on April 14 after landing on JetBlue Flight 470. Officials said the person then left the airport in a private vehicle and traveled out of state. (wcvb.com) Boston health officials said there are no other known exposure points in Boston tied to this case. They said they are working with partners to identify and notify people who may have been exposed. (wcvb.com) 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. The Centers for Disease Control and Prevention says measles is vaccine-preventable and among the most contagious infectious diseases. (cdc.gov) The Centers for Disease Control and Prevention says up to 9 out of 10 susceptible people with close contact to a measles patient will become infected. That makes airports a concern because large numbers of travelers move through enclosed spaces in short windows of time. (cdc.gov) Massachusetts public health officials have dealt with other airport-related measles alerts in the past year, including a December notice involving possible exposures at Logan Terminals B and C. State officials also announced two confirmed measles cases in Massachusetts residents in March 2026. (mass.gov 1) (mass.gov 2) Massachusetts says measles usually begins with high fever, cough, runny nose, and red, watery eyes before a rash appears. The state advises people who develop symptoms after an exposure to call a healthcare provider before going to a clinic or emergency department. (mass.gov) The Centers for Disease Control and Prevention says the measles, mumps, and rubella vaccine offers the best protection. At Logan, the immediate question for travelers is whether they were in Terminal C during that April 14 window and whether their vaccination is up to date. (cdc.gov)
