The Philadelphia Department of Public Health is warning travelers of a possible measles exposure at Philadelphia International Airport earlier this month.
Health officials said an individual with measles traveled through Terminal E on Thursday, Feb. 12, 2026, between 1:35 p.m. and 4:30 p.m. Anyone who was in that area during that time may have been exposed.
The department said it believes there is no ongoing threat to the general public but is urging potentially exposed individuals to review their vaccination status and monitor for symptoms through March 5.
Measles is a highly contagious virus that spreads through the air when an infected person coughs, sneezes or talks. The virus can linger in the air for up to two hours after an infected person leaves the area. Early symptoms include fever, runny nose, cough and red, watery eyes, followed by a rash. In severe cases, measles can lead to pneumonia, brain swelling and death.
“We believe there is no threat to the general public associated with this case of measles,” said Health Commissioner Dr. Palak Raval-Nelson. “We encourage people who were possibly exposed to take action if they are not protected against measles."
Raval-Nelson noted that measles outbreaks are occurring in several countries and parts of the United States, including a large ongoing outbreak in South Carolina, increasing the risk of travel-related cases.
Health officials strongly recommend that parents follow the routine immunization schedule and ensure children are fully vaccinated. The measles, mumps and rubella (MMR) vaccine is typically given in two doses — first at 12 to 15 months of age and again between 4 and 6 years old — and is considered safe and highly effective.
Infants younger than 12 months are not routinely eligible for the vaccine and are not fully protected. However, infants 6 to 11 months old should receive an early dose before international travel. Families planning travel outside the United States or to areas experiencing outbreaks are advised to consult their child’s doctor at least two weeks before departure.
The Health Department said people are generally considered immune if they were born before 1957, previously had measles, or received two doses of a measles-containing vaccine, usually the MMR vaccine. Those unsure of their status should check vaccination records or contact their health care provider.
Individuals who have received only one dose are considered at low risk but should speak with their provider about completing the second dose.
If you are protected from measles, you do not have to do anything; MMR vaccines are extremely effective at preventing measles, health experts said.
Those who are unvaccinated, pregnant and not immune, immunocompromised, or caring for infants under 12 months should contact their health care provider as soon as possible for guidance. Because measles is contagious from four days before to four days after a rash appears, officials advise unvaccinated people who may have been exposed to wear a mask in indoor public settings and around unvaccinated individuals for 21 days following exposure.
Anyone who develops symptoms consistent with measles should immediately contact their doctor and inform them of the possible exposure before seeking in-person care.
