NEW YORK – New York City health officials have confirmed one case of measles this week involving an unvaccinated infant with recent international travel.
The NYC Health Department said it is working to identify and notify people who may have been exposed. Officials emphasized that the risk to the public remains low due to high vaccination rates across the city.
As of June 30, 2025, 93% of NYC children ages 24 to 35 months had received at least one dose of the measles, mumps and rubella (MMR) vaccine by their second birthday.
Health officials said measles cases are increasing globally and in parts of the United States due to declining vaccination rates. However, they stressed that the MMR vaccine remains the best protection against the highly contagious and potentially deadly disease.
The Health Department strongly urges parents to ensure children receive their first MMR dose at 12 months and a second dose between ages 4 and 6. Infants ages 6 to 11 months traveling internationally should receive an early, additional dose before travel.
Most adults in New York City are protected and do not need additional doses. Those unsure of their vaccination status are advised to consult their health care provider.
Officials noted that while measles is not widespread in the United States due to high vaccination rates, it remains common in other parts of the world and is sometimes brought into the country by unvaccinated travelers. To date, there have been no cases in New York City linked to the current outbreak in South Carolina.
The Health Department said it routinely investigates cases to determine where exposure may have occurred and works closely with schools and health care facilities when necessary.
Providers and laboratories are required to report measles cases to the city.
More information about measles and vaccination is available through the NYC Health Department.
