Travelers passing through Newark Liberty International Airport earlier this month may have been exposed to measles.
The New Jersey Health Department issued a public advisory Monday after a traveler with the viral disease visited the massive New Jersey airport.
The sick flier, who was not a New Jersey resident, passed through Terminal B on Oct. 19, between 2:15 pm and 5:30 pm, according to health officials.
Measles is a highly contagious virus that can cause a high fever, coughing, runny nose, watery red eyes, and a full-body rash.
More serious symptoms of the virus include pneumonia, brain swelling (encephalitis), miscarriage, premature birth or low birthweight.
In extremely rare cases, measles infections could trigger subacute sclerosing panencephalitis (SSPE), a neurological disease that can cause mood swings, severe brain damage and death. It killed a Los Angeles school-aged child earlier this year.
Passengers who were exposed to measles at Newark airport may not develop symptoms until Nov. 9, authorities said. The virus can incubate for 11-12 days, according to the Centers for Disease Control.
New Jersey has had 11 cases of measles in 2025, up from seven in 2024.
There have been 27 confirmed measles cases in New York in 2025, including 18 in New York City, according to the state Department of Health. Fourteen cases were reported in New York City in 2024, and zero cases were reported the previous three years.
Measles cases hit a 33-year high nationwide in 2025, with 1,648 confirmed cases in 42 states, and 23 cases were reported among international travelers to the U.S., according to the CDC.
People fearing exposure were encouraged to contact their local health department before visiting their doctor or a hospital. The NJ Health Department did not return calls to The Post.
