Measles Exposure Alert Issued at Newark Airport: Authorities Urge Vaccination to Prevent Outbreak

Health officials in New Jersey have issued a warning to travelers following confirmation of a measles case at Newark Liberty International Airport earlier this month. According to the New Jersey Department of Health (NJDOH), a non-resident who passed through the airport on May 12 has since tested positive for measles, raising concerns about potential exposure among others present at the time.

The department outlined specific times and locations within the airport where individuals may have been exposed to the virus. Passengers and staff who were present during those periods are being asked to remain vigilant for symptoms of measles, which can take up to 21 days to develop—meaning new cases could potentially emerge through June 2.

Measles is a highly contagious virus, transmitted primarily through airborne respiratory droplets from coughing or sneezing. The virus can linger in the air for up to two hours after an infected person has left, making public spaces such as airports particularly vulnerable settings for transmission.

Symptoms of measles include:

• High fever
• Cough
• Runny nose
• Red, watery eyes
• A distinct rash that typically starts on the face and spreads down the body

The NJDOH is urging parents and caregivers to ensure children are up-to-date on their measles, mumps, and rubella (MMR) vaccinations—a critical step in preventing further spread. Health officials emphasize that those most at risk are individuals who are unvaccinated or only partially vaccinated.

"The best protection against measles remains two doses of the MMR vaccine," the health department stated, underscoring that even infants aged six to eleven months should receive a dose before international travel. Older children are advised to complete their full vaccination schedule, with two doses administered after their first birthday.

If someone believes they may have been exposed or is experiencing symptoms consistent with measles, the NJDOH recommends contacting a healthcare provider before visiting a medical office or emergency room to prevent further transmission.

As of May 15, no additional cases linked to the initial incident have been identified in New Jersey. However, the situation remains under close surveillance, and health officials continue to encourage vigilance and vaccination, particularly for those planning to travel abroad in the coming weeks.

The latest warning comes just days after the region's air traffic control system experienced significant disruption, compounding anxiety for both travelers and officials. The NJDOH maintains its commitment to keeping the public informed as the situation evolves.
