SEATTLE (AP) — 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.
