The New Jersey Department of Health issued a warning about potential measles exposure at Shakira’s concert at MetLife Stadium that occurred on May 15th, 2025.
An out-of-state attendee was infectious during the event, which drew tens of thousands. Symptoms may appear as late as June 6 due to the virus’s 7 to 14 day incubation period.
Measles is highly contagious, spreading through coughs or sneezes, with droplets lingering in the air for up to two hours. Unvaccinated individuals are at high risk, with 90% of unvaccinated close contacts likely to contract the disease.
Symptoms include high fever, cough, runny nose, watery red eyes and a rash starting at the hairline. Complications can be severe, especially for young children, including pneumonia or encephalitis.
The CDC reports 1,024 measles cases across 30 U.S. states in 2025, the largest outbreak since 2000. Concertgoers are urged to check vaccination status, monitor symptoms and contact healthcare providers before visiting medical facilities to prevent further spread.
No confirmed cases linked to the concert have been reported as of May 21st.
