New Jersey health officials have issued a warning about measles exposure at Newark Liberty International Airport.

Officials say that a traveler who has been confirmed to have measles was in the airport on March 4. The traveler, who was not identified, arrived from Aruba. The traveler then departed for California from Terminal C.

Anyone who was inside the airport between March 4 at 9 p.m. and March 5 at 9:30 a.m. could have been exposed. New Jersey residents identified as potentially exposed on the ill individual’s flights will be notified by their local health department, according to officials.

Measles is a highly contagious disease. Symptoms include rash, high fever, cough, runny nose and red, watery eyes. Symptoms could show up as late as March 26.

Anyone who feels that they may be at risk from the exposure is urged to contact their health care provider before seeing treatment. This is to prevent unnecessary exposure.

Health officials are also urging all New Jersey residents to receive the measles vaccination.
