Public health officials in the Seattle area are alerting residents to potential measles exposures at several locations across King County. The warnings follow the confirmation of two measles cases in county residents this year, raising concerns about a potential resurgence of the highly contagious virus. While measles was effectively eliminated in the U.S. In 2000, outbreaks continue to occur, often linked to travel and declining vaccination rates. This latest cluster underscores the importance of vaccination as the most effective protection against the disease.
The King County cases represent a slight increase from recent years. Public Health – Seattle & King County reported seven cases in 2025 and three cases each in 2024 and 2023. Prior to that, no cases were identified in the county in 2022 or 2021. It’s crucial to note that these figures only reflect cases among King County residents; individuals traveling through the area while contagious are not included in the tally.
The recent exposures occurred in late March at a variety of locations in Kirkland, Bellevue, and Seattle. Due to the fact that the measles virus can remain airborne for up to two hours after an infected person leaves a space, health officials are urging anyone who visited these locations during the specified times to be vigilant for symptoms. The potential exposure sites include restaurants, urgent care facilities, and hospital emergency departments, highlighting the virus’s ability to spread in common public spaces.
Potential Exposure Locations and Dates
Public Health – Seattle & King County has identified the following locations and times as potential exposure sites:
- March 21, 6:30 p.m. To 9:30 p.m. — Vovina, 15 Lake St. S, Kirkland
- March 21, 7:45 p.m. To 11:45 p.m. — Ristorante Paradiso, 120 Park Lane, Kirkland
- March 24–25, 8 p.m. To 2 a.m. — Kaiser Permanente Bellevue Medical Center urgent care
- March 26–27, 6:45 p.m. To 2:30 a.m. — Kaiser Permanente Bellevue Medical Center urgent care
- March 28, noon to 3 p.m. — Northcut Landing Building, including UW Medicine urgent care at Ravenna
- March 28, 1 p.m. To 10:30 p.m. — UW Medical Center-Montlake

Individuals who were present at these locations during the listed times and are not fully vaccinated against measles are advised to monitor for symptoms. The incubation period for measles is typically 7-21 days, meaning symptoms are likely to appear between March 28 and April 20, depending on the date of exposure.
Understanding Measles and Its Symptoms
Measles is a highly contagious viral infection that spreads through the air when an infected person coughs or sneezes. Symptoms typically start with a high fever, cough, runny nose, and red, watery eyes – often referred to as the “three C’s.” Within a few days, a characteristic rash develops, usually starting on the face and spreading down the body. The rash can be blotchy and red, and may be accompanied by small white spots inside the mouth, known as Koplik’s spots.
As a board-certified physician, I want to emphasize that measles can lead to serious complications, especially in young children and individuals with weakened immune systems. These complications can include pneumonia, encephalitis (inflammation of the brain), and even death. Vaccination is overwhelmingly effective in preventing these outcomes.
Vaccination Remains the Best Defense
The Centers for Disease Control and Prevention (CDC) recommends that all children receive two doses of the MMR (measles, mumps, and rubella) vaccine, with the first dose administered between 12 and 15 months of age and the second dose between 4 and 6 years of age. The CDC website provides comprehensive information about measles, vaccination schedules, and outbreak information.
For adults who are unsure of their vaccination status, or who have never been vaccinated, it is recommended to consult with a healthcare provider to determine if vaccination is appropriate. While the MMR vaccine is highly effective, it is not 100% effective in all individuals. But, even in those who are vaccinated and still contract measles, the illness is typically milder.
What to Do If You Suspect Measles
If you believe you may have been exposed to measles and develop symptoms, it is crucial to contact your healthcare provider *before* visiting a clinic or emergency room. This allows healthcare facilities to take appropriate precautions to prevent further spread of the virus. Do not simply reveal up at a medical facility, as you could potentially expose others. Your healthcare provider can advise you on testing and treatment options.
