New York City health officials are investigating a confirmed case of measles in an unvaccinated infant who recently traveled internationally. NBC New York reports that authorities are working to identify and notify anyone who may have been exposed to the virus.
Health officials emphasized that measles is a highly contagious virus that can cause fever and rash. FOX 5 New York reports that up to 90% of unvaccinated or non-immune individuals in close contact with an infected person may also become infected. The NYC Health Department is working to inform those at risk and stresses the importance of vaccinating children with the MMR vaccine.
As of June 30, 2025, 93% of children in New York City aged 24 to 35 months had received at least one dose of the MMR vaccine by their second birthday. High vaccination coverage is important for public health because it helps reduce the risk of widespread measles outbreaks. With global measles cases rising and localized increases in the United States linked to lower vaccination rates, NYC officials continue to highlight the MMR vaccine as the primary protection against the disease.
Health officials recommend that children receive the first MMR vaccine dose at 12 months and a second dose between ages 4 and 6. Infants aged 6 to 11 months who are traveling internationally are advised to receive an early additional dose before departure. Most adults in New York City are already protected, but those uncertain of their vaccination status are encouraged to consult a healthcare provider.
Following the recent case, the NYC Health Department is conducting trace-back efforts to identify possible exposure locations and is coordinating with schools and healthcare facilities as needed. The department emphasizes that providers and laboratories are required to report any measles cases to enable timely public health action. Resources on measles and vaccination are available through the NYC Health Department.
