TRENTON, N.J. — The New Jersey Department of Health (NJDOH) is warning residents of possible exposure to measles after an out-of-state individual who later tested positive for the virus attended Shakira’s sold-out concert at MetLife Stadium while infectious.
The exposure may have occurred between 7:30 p.m. on May 15 and 1:00 a.m. on May 16. NJDOH advises that individuals who were at the stadium during that time could develop symptoms as late as June 6. The department is urging the public to monitor for signs of illness and confirm their vaccination status, particularly with the measles, mumps, and rubella (MMR) vaccine.
Measles symptoms typically include high fever, cough, runny nose, red eyes, and a spreading rash that begins on the face and progresses downward. The disease is highly contagious and can result in serious complications, including pneumonia and encephalitis. In pregnant individuals, it may also lead to miscarriage, premature birth, or low birth weight.

As of Monday, no additional measles cases linked to the May 15 exposure have been reported in New Jersey. Health officials stress that anyone who believes they may have been exposed should contact a healthcare provider before visiting a medical facility. This step is intended to minimize potential exposure to other patients and staff.
High-risk individuals urged to verify vaccination status
The measles virus can remain airborne for up to two hours after an infected person has left an area, according to NJDOH. It can also spread through contact with mucus or saliva. Those at greatest risk include people who are unvaccinated or who have not previously had the disease.

The two-dose MMR vaccine is described by health authorities as safe and effective at preventing not only measles but also related complications. NJDOH encourages all residents to confirm they are current with routine immunizations, particularly if traveling abroad, where exposure risk may be higher.
Infants between 6 and 11 months of age should receive one dose of MMR before international travel, followed by two additional doses after their first birthday to complete the recommended immunization schedule.
Officials continue to monitor for new cases and reiterate the importance of early identification and prevention to contain the spread of the virus.
