King County health officials have confirmed a measles infection in an adult traveler from Brazil who visited Seattle last week while contagious.
The case is not related to a measles outbreak linked to Disneyland in Orange County, Calif. Through the end of January, more than 100 people were sickened in 14 states, with most cases tied to the theme park, according to federal officials. Two of those cases were confirmed in siblings from Gray’s Harbor County after a teen girl visited Disneyland in mid-December.
The traveler from Brazil, who was unvaccinated, likely was exposed in the individual’s home country, health officials said. Before being diagnosed with measles, the traveler was in the following public locations Jan. 25. Anyone who was at these sites during the specified times was likely exposed to measles.
- 8 to 10 a.m.: Common areas of the Sheraton Hotel, 1400 Sixth Ave., Seattle.
- 9 a.m. to 1 p.m.: Seattle-Tacoma International Airport, main terminal and Concourse D.
Measles is a highly contagious virus that can linger in the air for an hour. People who aren’t immune, either through vaccination or previous illness, could have become infected after exposure, with symptoms likely appearing between Feb. 1 and Feb. 15. Symptoms include fever, cough, red watery eyes and a full-body rash.
There have been three confirmed cases among Washington state residents this year, health officials said. An infant from King County was confirmed to have measles last week. The child had no known association with Disneyland travel, a state health official said.
People at highest risk for infection and complication include those who are unvaccinated, pregnant women, infants under six months and people with weakened immune systems.
Measles was eradicated in the U.S. in 2000, but last year saw more than 640 cases, mostly spread by infected travelers who transmitted the disease to unvaccinated people, according to the Centers for Disease Control and Prevention.
