The New Jersey Department of Health has issued a warning regarding exposure to a case of measles said to be from traveling.

According to NJDOH, the confirmed case is a resident of Somerset County and developed measles following travel from a country that is currently experiencing an ongoing outbreak of measles.

The exposure was potentially June 1 between 12 p.m. and 3:30 p.m. in the emergency department at Penn Medicine Princeton Medical Center in Plainsboro.

Symptoms from exposure could develop as late as the end of this month. NJDOH recommends that anyone who visited the location listed above during the specified date and times should contact a health care provider immediately to discuss potential exposure and risk of developing the illness.

NJDOH says it's doing contract tracing. No other cases have been reported.

The virus is easily spread through the air when someone coughs or sneezes and can remain in the air for up to two hours after an infected person leaves the area, according to NJDOH. People can also get sick when they come in contact with mucus or saliva from an infected person.

Individuals at risk include those who have not been fully vaccinated or have not had measles in the past.
