A person infected with measles passed through Philadelphia International Airport on the Fourth of July, and the city's health department is now urging anyone who was in the terminal area that morning to confirm their vaccination status and watch for symptoms through July 25.
The Philadelphia Department of Public Health announced July 11, 2026 that an individual with measles was traveling through PHL and was present in Terminals A, B, and C on Saturday, July 4, between 7:30 a.m. and 11:15 a.m. Anyone who was in those terminals during that window who is not immune to measles may have been exposed.
