Key Takeaways
• Measles exposure risk at Newark Liberty Terminal B on May 12, 2025, from 12:30 p.m. to 5:00 p.m.
• NJ Department of Health urges travelers to monitor for symptoms until June 2, 2025; vaccination is emphasized.
• No new related cases reported as of May 15, 2025, but vigilance and prompt action are still recommended.
Travelers passing through Newark Liberty International Airport now face a new health concern after state health authorities warned of possible measles exposure. The warning came after a person with a confirmed case of measles spent over four hours in Terminal B at the airport on May 12, 2025. During this time, the individual, whose identity has not been shared with the public, may have spread the highly contagious virus to others in shared spaces at the airport. The New Jersey Department of Health (NJDOH) quickly issued a statement to alert anyone who was in Terminal B of the risk and provided advice on how to respond.
What Happened at Newark Liberty International Airport?
On May 12, 2025, from 12:30 p.m. to 5:00 p.m., a person with measles was present in Terminal B at Newark Liberty International Airport, as officially confirmed by the NJDOH. This person’s movements through various parts of Terminal B during these hours made it possible for others nearby or even those who entered the terminal afterward to be exposed. Because measles can remain in the air for up to two hours after an infected person leaves, even short visits to Terminal B during or soon after this period could carry risk.
Anyone who was at Terminal B on May 12, between 12:30 p.m. and 5:00 p.m., is urged to watch for measles symptoms. These symptoms may not appear right away, as the virus often takes between 7 and 21 days from exposure to cause signs of illness. That means those exposed could start showing symptoms as late as June 2, 2025. As of May 15, 2025, health officials reported that there have been no new cases linked to this specific exposure in New Jersey. Still, vigilance remains the key advice from health authorities.
Why Measles Exposure Matters at Airports
Measles spreads more easily than many other viruses. If one person brings measles into a crowded space, it can affect people who have no protection. This is especially troublesome in busy hubs like Newark Liberty International Airport, where international travelers arrive and depart daily. Airports bring together people from many different places, including some where vaccination rates might be lower or outbreaks may occur more often.
Terminal B at Newark Liberty International Airport is used for international flights as well as some domestic ones, which increases the number of people moving through shared areas like waiting lounges, security lines, shops, and restrooms. These spaces are perfect places for the virus to move from one person to another, especially when travelers may not know they’re sick or haven’t developed symptoms yet.
Airports, therefore, must pay close attention to infectious diseases like measles. Even one case, as seen here, can cause health alerts for hundreds or thousands of travelers. Monitoring, rapid response, and clear information help limit the risk and keep people safe.
What Is Measles and Why Is It So Contagious?
Measles is a serious disease caused by a virus that spreads through the air when an infected person coughs or sneezes. Even after the sick person leaves, the virus can linger in the air or on surfaces for up to two hours. People nearby, even if they only passed through the area, can breathe in the virus and get sick.
The symptoms of measles can be easy to miss at first because they are similar to many other illnesses. Early signs include:
- Fever
- Cough
- Runny nose
- Red, watery eyes
A few days later, a rash usually appears. This rash starts on the face and then moves down to the rest of the body. The rash is an important clue for doctors. Measles can bring serious health problems, including pneumonia, swelling of the brain, or, in rare cases, death—especially in young children, pregnant women, or people with weak immune systems.
The NJDOH emphasizes that most people who get measles are those who have not received the entire recommended series of vaccinations. In the case of the Newark Liberty International Airport exposure, officials pointed out that those at highest risk are people who have not received any measles vaccine or only got one dose instead of the full two-dose series.
The Role of Immunization
According to the NJDOH, the best defense against measles is receiving two doses of the MMR (measles, mumps, and rubella) vaccine. People who are vaccinated are much less likely to get measles, and if they do, their illness tends to be milder.
The two-dose schedule is important because, after only one dose, about 93 out of 100 people are protected. The second dose raises that protection level to about 97 out of 100 people. This added layer makes it less likely for an outbreak to spread, even if someone is exposed.
Parents and caregivers are strongly advised to make sure everyone in their family is up to date on the MMR vaccine, especially before traveling through crowded places like Newark Liberty International Airport. For more details about how to get vaccinated or check immunization records, you can visit the official New Jersey Department of Health page on measles prevention.
Monitoring for Symptoms and What to Do
Following exposure at places like Terminal B, the NJDOH advises anyone who was present between 12:30 p.m. and 5:00 p.m. on May 12, 2025, to pay close attention to their health until at least June 2, 2025. If you develop fever, cough, runny nose, red eyes, or a rash, you should:
- Stay home and avoid contact with others to prevent spreading the illness
- Call your doctor or clinic before going in for care, especially if you may have been exposed to measles
- Let your health care provider know about where and when you may have been exposed, including your presence at Newark Liberty International Airport’s Terminal B on the specified date and time
Doctors may need to run special tests to confirm if you have measles. It’s important for them to know about possible exposures so they can protect other patients and staff.
Patterns and Context: Previous Measles Exposure at Newark Liberty International Airport
This week’s warning is not the first time the airport has had to respond to a measles risk. In March 2025, there was another confirmed case at Newark Liberty International Airport. In that earlier incident, the person with measles was not from New Jersey but from Kent County, Michigan. They had just returned from a trip overseas and passed through the airport while they were contagious.
Health officials warned that anyone who visited the airport during that March incident could develop measles symptoms up to April 17, 2025. While not everyone exposed became ill, these repeated cases point to a real challenge at busy airports: diseases like measles find it much easier to spread in places where people from different backgrounds, vaccination histories, and countries meet and spend time together.
The March case involved someone who likely picked up measles while traveling abroad, then brought it into the United States 🇺🇸. Airports such as Newark Liberty International welcome millions of travelers every year, which means exposure to international diseases remains a constant possibility.
The Bigger Picture: Why These Incidents Matter
Measles was once thought to be nearly wiped out in the United States 🇺🇸, but gaps in vaccination and international travel have let it return in some places. When measles cases show up at major airports, it’s not just a local problem—it can quickly become an issue for people from across the country and around the world.
Here’s why these exposures spark concern:
- Travelers returning from places where measles is more common can unknowingly bring the virus back home.
- Unvaccinated people are more vulnerable, especially babies too young to get the vaccine.
- Airports are unique because they bring together people from many places—places where outbreaks might be happening and vaccine rules might differ.
- Even one case at an airport can spark alerts that reach hundreds of flights and possibly impact thousands of people.
The NJDOH’s response highlights the need to keep vaccination rates high, especially among travelers and people working at busy airports. As reported by VisaVerge.com, health officials believe that if more people are vaccinated, the virus has less chance to spread, making similar health alerts less likely in the future.
Implications for Immigrants, Travelers, and Employers
Measles exposure incidents at Newark Liberty International Airport affect many groups, including immigrants, long-term visitors, and international students. Many countries have different vaccination schedules, and some immigrants may not have had access to the MMR vaccine or may be unsure of their vaccination history.
- For immigrants and visitors to the United States 🇺🇸: Before traveling, it is wise to check with health officials or your doctor to see if you need the MMR vaccine. Some immigration processes, such as applying for certain visas or green cards, may require proof of vaccination against measles and other diseases. The exposure at Newark Liberty International Airport is a reminder to keep vaccination records up to date.
- For employers with international staff: Companies that employ workers who travel through major airports like Newark Liberty International Airport should encourage employees to stay current on vaccines. Some workplaces may also provide resources or time off for employees to get vaccinated.
-
For international students: U.S. colleges and universities often require proof of the MMR vaccine before students can attend classes or live on campus. Traveling through large airports can increase the risk of exposure, so up-to-date vaccination is key.
What Authorities Are Doing—and What You Can Do
After the recent exposure, the NJDOH has ramped up their communication. Signs alerting travelers about measles exposure have been posted in Newark Liberty International Airport, especially near Terminal B. Airport workers, airlines, and cleaning crews have been notified and given guidance on what to do if they begin to feel sick or notice symptoms among others.
Travelers are urged to:
- Keep a copy of their vaccination records handy, especially when traveling abroad or through major airports
- Stay informed about health alerts on the official Centers for Disease Control and Prevention Travel Health Notices
- If you or your children develop symptoms, seek care promptly and inform your provider about possible exposures
Lessons and Ongoing Challenges
The recent events at Newark Liberty International Airport, especially in Terminal B, serve as a reminder that even diseases once thought to be under control can return when vaccination rates drop or when people are exposed during international travel. The quick response of health officials, issuing timely alerts and sharing clear steps for at-risk people to follow, helps reduce panic and keeps those affected informed.
But these incidents also show some ongoing challenges:
- Keeping up with vaccinations: Not everyone has easy access to health care or vaccine records, especially new immigrants or recent arrivals.
- Tracking and following up: With airports as busy and crowded as Newark Liberty International Airport, reaching everyone who might have been in Terminal B during the exposure window takes time and resources.
- Disinformation or confusion: Some people may not take health alerts seriously or may get wrong information about vaccine safety.
Conclusion: Planning Ahead in a Global World
Travel through Newark Liberty International Airport, like many large airports, brings great opportunity but also some risk. The recent measles exposure in Terminal B highlights the need for simple public health measures: vaccination, early detection, clear communication, and respect for health alerts.
People who might have passed through the airport during the risk period should keep an eye on possible symptoms and talk to their doctor if they have any concerns. Immigrants, students, and international travelers should make vaccination a priority, using official sources to check requirements and track their records.
As people continue to move across borders, airports like Newark Liberty International Airport will keep watching out for health issues and working with public health teams to keep everyone safe. Steps like these don’t just help one city or state—they make travel safer for everyone. For continued updates and complete details on measles and travel health, consult trustworthy outlets and maintain your own health paperwork.
