There was a possible measles exposure at Philadelphia International Airport

Key Points:

• Philadelphia health officials warn of potential measles exposure at Philadelphia International Airport between Sept. 13, 7:25 p.m., and Sept. 14, 12:05 a.m., involving Terminals B and F and connecting areas to Terminals C, D, and E.
• The exposure is unrelated to recent cases at the Children’s Hospital of Philadelphia, and officials advise those potentially exposed to verify vaccination status and monitor for symptoms, especially vulnerable groups such as infants, pregnant women, and immunocompromised individuals.
• Pennsylvania is experiencing the nation’s largest measles outbreak this year, with over 760 cases and four confirmed deaths, primarily centered in Lancaster and spreading to suburban Chester County, affecting more than half of the state's counties.
• The measles, mumps, and rubella (MMR) vaccine is 97% effective with two doses, but declining vaccination rates have led to a resurgence; about 90% of unvaccinated individuals exposed to measles will contract the disease.
• Health officials emphasize the importance of staying up to date on vaccinations to protect individuals and vulnerable populations, urging residents to seek medical advice promptly if exposed or symptomatic and to visit phila.gov/measles for more information.
