Some opera-goers are getting an encore they definitely did not want. People who attended a Metropolitan Opera performance at Lincoln Center in April have been warned they may have been exposed to measles, according to local health officials and media reports. The alert comes as New York City looks into a small number of imported cases this year, and anyone unsure of their MMR vaccination status is being urged to check records and talk with a health care provider if symptoms show up.
According to CBS News New York, the notice does not name a specific performance, only that it involved a Met show in April. Attendees are being told to keep an eye out for fever, cough and the classic measles rash. Health officials want anyone who thinks they were exposed to call a clinician before heading to a clinic or emergency room so isolation steps can be set up in advance.
Context: Measles In New York City
The city’s health department reports there have been five confirmed measles cases in New York City so far in 2026. Guidance on exposures and reporting is posted by NYC Health, which urges providers to report suspected cases right away. Separate coverage from NBC New York notes that several of the recent local infections have been linked to international travel.
How Measles Spreads And Post-Exposure Options
Measles is notoriously contagious. Viral particles can linger in the air for up to two hours after an infectious person leaves an indoor space, and symptoms usually appear about 10 to 16 days after exposure. According to the Centers for Disease Control and Prevention, getting an MMR dose within 72 hours of exposure may prevent illness. For people who cannot receive the vaccine, immune globulin can be offered within six days. Anyone who develops fever, cough or a rash after a known or suspected exposure is urged to call a health care provider first and mention the possible measles contact so steps can be taken to reduce further spread.
What To Do If You Attended The Met
If you were at a Met performance in April and do not have documentation of two MMR doses, health officials say it is time to dig up those records or ask your clinician about your immunity status. The NYC Health Department advises calling your provider before showing up in person and offers a Provider Access Line for suspected measles cases at 866 692 63641. New Yorkers can also call 311 for help finding vaccine locations and clinic information.
People who are unvaccinated and still within 72 hours of exposure may be eligible for an MMR dose, while pregnant people, infants and those who are immunocompromised should talk with a clinician about whether immune globulin is appropriate.
High vaccination coverage has generally kept measles from spreading widely in New York City, but officials warn that even a single imported case can pose a threat in under-vaccinated pockets. If you are worried about exposure or develop symptoms after attending a performance, contact your clinician or the city health department to ask about testing and next steps. This story will be updated if the Metropolitan Opera or city officials release additional details.
