SEATTLE -- Public health officials say a contagious traveler with measles passed through Seattle-Tacoma International Airport on Thursday.

Measles is a highly contagious virus but most people in Washington are immune because they have been vaccinated.

The disease is mainly spread through the air when a person with measles coughs or sneezes.

People at highest risk from exposure are the unvaccinated, pregnant women, infants under six months of age and those with weakened immune systems. Anyone who may have been exposed and who develop an illness with fever or an unexplained rash between July 11 and July 25 should call their health care provider.

The contagious traveler flew from Beijing to Seattle on July 4. A King County spokesperson said anyone in the following areas between noon and 4 p.m. that day may have been exposed:

  • South Satellite International Terminal Arrival Area
  • Immigration and primary screening
  • Adoption processing
  • Restrooms in the South Satellite
  • Baggage Claim/Customs
  • Train to main terminal
  • Main terminal baggage claim
  • Elevator in Main Terminal to Level 2 parking garage.

The Centers for Disease Control and Prevention is contacting people who were on the same flights as the contagious traveler.
