Health officials are asking recent travelers out of two D.C. airports to proceed with caution after they may have potentially been exposed to measles.

The Virginia Department of Health put out a news release Saturday saying it was aware of a person with a confirmed case of measles who recently traveled through Northern Virginia after returning from an overseas trip.

The potential exposure has been linked to the international arrivals area of the main terminal at Dulles International Airport between 4 p.m. and 8 p.m. local time on Jan. 3, and Terminal A at Ronald Reagan Washington National Airport between 2:30 p.m. and 6:30 p.m. on Jan. 4, the agency said.

Health officials are working to identify anyone who may have been exposed, including passengers on specific flights, officials said.
