SEATTLE -- An adult may have exposed Seattle-Tacoma International Airport travelers to measles last week while they were infectious, according to Public Health -- Seattle & King County.

The infected person traveled through Sea-Tac on Friday, Jan. 10. Public Health confirmed the person, who is an Alaska resident, has measles. They were likely exposed while abroad, Public Health said in a news release.

"Measles is highly contagious and if you don't have immunity, you can get it just by being in an area where a person with measles has been," said Dr. Eric Chow, communicable disease chief for Public Health -- Seattle & King County in the news release.

Those vaccinated against measles are unlikely to get infected. Two doses of the measles, mumps and rubella vaccine provides about 97% lifetime protection against infection.
