New Jersey health officials have issued a warning regarding potential measles exposure for attendees of Shakira’s “Las Mujeres Ya No Lloran” concert at MetLife Stadium in East Rutherford, New Jersey, on May 15, 2025. An individual diagnosed with measles attended the event while infectious, potentially exposing thousands of concertgoers to the highly contagious virus.
Details of the Exposure
The New Jersey Department of Health (NJDOH) confirmed that a non-New Jersey resident attended the concert between 7:30 p.m. on May 15 and 1:00 a.m. on May 16 while infectious. The exact seating location of the individual remains unknown. Health officials are urging attendees, especially those who are unvaccinated or have not previously contracted measles, to be vigilant for symptoms and to ensure they are up to date with the measles, mumps, and rubella (MMR) vaccination.
Symptoms and Incubation Period
Measles symptoms typically appear 7 to 14 days after exposure and include:
- High fever
- Cough
- Runny nose
- Watery red eyes
- A rash that usually begins at the hairline and spreads downward across the face, neck, torso, arms, legs, and feet
Individuals who were potentially exposed at the concert could develop symptoms as late as June 6, 2025. If you experience these symptoms, it is crucial to contact a healthcare provider before visiting any medical facility to prevent further spread of the virus.
Vaccination and Prevention
The MMR vaccine is the most effective way to prevent measles. It is administered in two doses and provides lifelong immunity against the virus. Health officials emphasize the importance of maintaining high vaccination coverage to prevent outbreaks and protect vulnerable populations.
Current Situation
As of the latest reports, no additional measles cases have been confirmed in New Jersey linked to this exposure. However, health authorities continue to monitor the situation closely. The Centers for Disease Control and Prevention (CDC) has reported over 1,000 measles cases across 31 states in 2025, marking a significant increase from previous years. The resurgence is attributed to declining vaccination rates and increased international travel.
Recommendations for Concertgoers
If you attended Shakira’s May 15 concert at MetLife Stadium, health officials recommend:
- Monitoring for Symptoms: Be aware of measles symptoms and seek medical advice if they develop.
- Vaccination Status: Ensure you are up to date with the MMR vaccine.
- Contact Healthcare Providers: If you suspect exposure or illness, call your healthcare provider before visiting any medical office or emergency department.
- Public Awareness: Stay informed about public health advisories and follow recommended precautions.
