Measles exposure alert at Seattle airport after Canadian traveler visits Washington state
Public health officials in Washington state are issuing a warning to residents after a Canadian traveler who was contagious with measles visited various public locations, including the Seattle-Tacoma International Airport. The individual’s vaccination status remains unknown, but they traveled through the airport and visited multiple areas in Renton, Bellevue, Seattle, Everett, and Woodinville between April 30 and May 3, according to a news release from King County.
The Canadian individual received the measles diagnosis after their visit to the area. It is important to note that individuals can be infected with measles for several days before showing any visible rash, and the virus can linger in the air for up to two hours after an infected person leaves the area.
Health officials have identified several potential exposure sites where the Canadian traveler visited, including Seattle-Tacoma International Airport, Bellevue Market Place at Factoria Shopping Center, Chateau Ste. Michelle Winery, Home Depot in Redmond, Dunn Lumber in Renton, Genki Sushi in Renton, Topgolf Renton Sport Bar and Restaurant, Pho Mignon in Kirkland, Kobo at HIGO Art Gallery, Uwajimaya Seattle Asian Market, Stoup Brewing, Spicy Style of Sichuan, a hotel, and three fitness centers.
While this case is not linked to any previous local measles cases, Public Health – Seattle and King County have responded to two other measles cases this year involving non-residents. In total, there have been five cases of measles in Washington state residents in 2025.
Meagan Kay, a medical epidemiologist for Public Health – Seattle and King County, noted a significant resurgence of measles both in the U.S. and globally. With over 1,000 cases reported nationally so far this year, 2025 is on track to have the highest number of measles cases in the U.S. since the early 1990s. Kay emphasized the importance of checking vaccination status and getting vaccinated if individuals are not protected.
Officials are urging anyone who may have been in the affected locations to verify their measles vaccination status and promptly contact a healthcare provider if they develop any symptoms such as fever or an unexplained rash.
It is crucial for the community to stay informed and take necessary precautions to prevent the spread of measles. Stay updated on vaccination recommendations and seek medical attention if any concerning symptoms arise. Let’s work together to prioritize public health and safety in our communities.
