Public Health Seattle and King County is warning residents of potential measles exposure at more than a dozen locations across the region following two confirmed cases in King County so far in 2026.
The agency confirmed that two King County residents have tested positive for measles as of 1 April, continuing an upward trend that saw seven cases in 2025, three in 2024, and three in 2023, after no cases were recorded in 2021 or 2022. Officials noted the figures reflect only King County residents and do not account for individuals who may have passed through the area while contagious.
Anyone who visited the following locations during the listed times may have been exposed and should monitor for symptoms. Measles can remain in the air for up to two hours after an infected person has left a space.
Potential exposure locations and times:
21 March, 11 a.m. to 2 p.m. — Costco Wholesale, N 205th Street, Shoreline. 21 March, 12:30 p.m. to 3 p.m. — Safeway, 15th Avenue NE, Shoreline. 21 March, noon to 2:30 p.m. — Habit Burger, N 205th Street, Shoreline. 21 March, 6:30 p.m. to 9:30 p.m. — Vovina, 15 Lake Street S, Kirkland. 21 March, 7:45 p.m. to 11:45 p.m. — Ristorante Paradiso, 120 Park Lane, Kirkland. 24 to 25 March, 8 p.m. to 2 a.m. — Kaiser Permanente Bellevue Medical Center urgent care. 26 to 27 March, 6:45 p.m. to 2:30 a.m. — Kaiser Permanente Bellevue Medical Center urgent care. 28 March, noon to 3 p.m. — Northcut Landing Building, including UW Medicine urgent care at Ravenna. 28 March, 1 p.m. to 10:30 p.m. — UW Medical Center Montlake. 28 March, 4:15 p.m. to 8:15 p.m. — Overlake Medical Center emergency department. 28 to 29 March, 11:30 p.m. to 2 a.m. — UW Medical Center Northwest emergency department. 28 to 30 March — UW Medicine Northwest Hospital, fifth floor.
