New Measles Case In King County With Ties To Sea-Tac, Renton

RENTON, WA — Health officials said Tuesday that a fourth confirmed case of measles has appeared in King County. In the most recent case, the person visited Sea-Tac Airport and the Valley Family Medicine clinic in Renton.

Health officials also said on Tuesday that the local measles cases likely stem from an unidentified person who was at Sea-Tac in the morning on April 25. Measles symptoms typically emerge between one and three weeks after exposure.

The case reported Tuesday is in a woman in her 30s, according to health officials. She visited Sea-Tac four times between May 10 and May 13. But King County officials said there's no current risk of catching measles by visiting the airport.

Here are the locations and times when the latest measles patient traveled while contagious, according to health officials:

• May 10, 2019, 4 a.m. to 2 p.m., Hudson Alki Bakery Store, Sea-Tac Airport
• May 11, 2019, 4 a.m. to 2:05 p.m., Hudson Alki Bakery Store, Sea-Tac Airport
• May 12, 2019, 4 a.m. to 2:05 p.m., Hudson Alki Bakery Store, Sea-Tac Airport
• May 13, 2019, 4 a.m. to 2:10 p.m., Hudson Alki Bakery Store, Sea-Tac Airport
• May 14, 2019, 10:40 a.m. to 1:45 p.m., Valley Family Medicine, 3915 Talbot Road, Renton
• May 15, 2019, 10:40 a.m. to 2 p.m., Valley Family Medicine

The three other confirmed cases in King County include a person from the Auburn area, and two women in their 50s and 40s who visited locations in Sammamish, Seattle, and Issaquah. A man from British Columbia visited Seattle in late April while contagious with measles and visited multiple locations, including the Space Needle and the Monorail. His case is not included in the county's tally.

Two people from Pierce County have been diagnosed with measles. A person from Snohomish County has been diagnosed, and that person visited locations in King County, including a Woodinville movie theater.

If you think you've been exposed, here are tips from King County health officials about what to do:

• Find out if you have been vaccinated for measles or have had measles previously. Make sure you are up-to-date with the recommended number of measles (MMR) vaccinations.
• Call a healthcare provider promptly if you develop an illness with fever or illness with an unexplained rash. To avoid possibly spreading measles to others, do not go to a clinic or hospital without calling first to tell them you want to be evaluated for measles.
• Vaccination or medication can be given after exposure in some cases to prevent illness — check with your healthcare provider. This is especially important for people at high risk for measles complications.
