The New Jersey Department of Health is warning that anyone who visited four Morris County locations between Nov. 6 and Nov. 11, 2026, may have been exposed to measles, after a person from outside the state was found to have the virus while traveling through New Jersey.
According to the department’s Nov. 13 alert, the possible exposures happened only at these places and times:
LegionsCon at the Hanover Marriott, 1401 Route 10 East, 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: from 9 p.m. Nov. 6 to noon Nov. 7, and from 5:45 p.m. Nov. 7 to 12:45 a.m. Nov. 11.
Walgreens, 203 South St., Morristown: Nov. 7 from 4:40 to 7:40 p.m.
Morristown Medical Center emergency department, 100 Madison Ave., Morristown: from 10:50 p.m. Nov. 10 to 1:30 a.m. Nov. 11.
People who were exposed and become infected could develop symptoms as late as Dec. 4, 2026, the department said. Measles typically starts with a high fever, cough, runny nose and red, watery eyes. A rash usually follows three to five days later, beginning at the hairline and spreading down the body.
Call before you go. State health officials ask anyone who suspects an exposure or illness to phone a health care provider or their local health department before showing up at any doctor’s office or emergency room, so staff can protect other patients.
As of Nov. 13, no other linked cases had been found in New Jersey, and the state is not in an outbreak, which the CDC defines as three or more related cases. Two doses of the MMR vaccine are 97% effective at preventing measles, the department said. Any new exposure sites will be posted on the state’s measles page.
