Health officials are investigating possible measles exposures after a non-New Jersey resident who was infectious visited multiple public locations across Morris County between Nov. 6 and Nov. 11.
Monitor Symptoms If Visiting These Morris County Locations
The New Jersey Department of Health issued an alert on Friday, Nov. 13, detailing the itinerary of the out-of-state visitor. Public health authorities are working with local officials on contact tracing and notifying individuals who may have crossed paths with the contagious visitor.
Anyone who visited the following locations during these specific windows is urged to monitor for symptoms:
- LegionsCon at Hanover Marriott (1401 N.J.-10 E., Whippany): Nov. 6 from 8:50 to 11 a.m., and Nov. 7 from 10 a.m. to 6:30 p.m.
- Sonesta Simply Suites Parsippany Morris Plains (100 Candlewood Drive, Morris Plains): Nov. 6 at 9 p.m. through Nov. 7 at noon, and Nov. 7 at 5:45 p.m. through Nov. 11 at 12:45 a.m.
- Walgreens Pharmacy (203 South St., Morristown): Store No. 10438 on Nov. 7 between 4:40 and 7:40 p.m.
- Atlantic Health Morristown Medical Center Emergency Department (100 Madison Ave., Morristown): Nov. 10 from 10:50 p.m. through Nov. 11 at 1:30 a.m.
Health officials note that potentially exposed individuals could develop symptoms as late as Dec. 4. As of Friday, no additional associated cases had been identified in New Jersey, and the state is not currently experiencing an outbreak, which the Centers for Disease Control and Prevention defines as three or more related cases.
How Measles Spreads and Progresses Through the Body
Measles is a highly contagious airborne virus that spreads when an infected person coughs or sneezes. The virus can remain suspended in the air for up to two hours after an infectious individual leaves a room. Transmission can also occur via saliva or mucus from someone carrying the virus.
“The rash usually begins as flat red spots that appear on the face at the hairline and spread downward to the neck, torso, arms, legs, and feet,” the health department said, describing the classic progression that typically follows initial symptoms like a high fever, cough, runny nose, and watery red eyes.
State health officials also warn that the disease can trigger severe medical complications, including pneumonia, encephalitis or brain swelling, alongside pregnancy risks such as low birth weight, premature birth, or miscarriage. Individuals seeking guidance for infants between 6 and 11 months old should note that state health authorities recommend an initial measles, mumps, and rubella dose prior to travel, followed by two additional doses after the child turns one.
State health officials warn that special arrangements can be made for evaluation while protecting medical staff and other patients from transmission. Anyone who suspects they were exposed or who develops an illness is instructed to contact a local health department or healthcare provider before visiting any medical office or emergency room so facilities can prepare.
Vaccination Protects Against Rising National Measles Activity
State authorities continue to emphasize immunization as the most effective defense against the virus. Two doses of the measles, mumps, and rubella vaccine are 97% effective at preventing infection and complications.
The alert comes as federal health data shows elevated measles activity across the United States. According to the CDC, the country recorded 5,182 confirmed cases and 43 new outbreaks across 47 jurisdictions as of Nov. 6.
Local medical professionals have expressed concern regarding community protection levels as national elimination status faces evaluation. Katharine Clouser of Hackensack University Medical Center addressed how this affects vulnerable populations:
The concern is that, as we continue to lose elimination status, that people can no longer rely on the community-based immunity that we had before. So having that herd immunity for people who are too young to receive the vaccine, or maybe those who are immunocompromised and can’t receive it, can’t rely on those around us.

Health agencies advise residents to verify their immunization records, particularly before undertaking international travel or visiting areas experiencing active outbreaks.
