Snohomish County Reports Measles Cases

SNOHOMISH COUNTY, Wash. — The Snohomish County Health Department has reported three new cases of measles linked to children exposed to a visiting family from South Carolina.

These three cases indicate that the disease is now spreading locally, which the health department refers to as an outbreak.

On January 14, three children tested positive for the measles virus. They exhibited symptoms such as fever, cough, and rashes typical of the illness.

Importantly, these children were not vaccinated against measles.

Dr. James Lewis, the health officer for Snohomish County, stated, “We expect additional cases to arise from previous exposures, as well as these new instances. While we hope to contain it, there are already multiple exposure sites, and it’s possible there are more cases out there that we haven’t identified yet.”

Generally, the health department noted that most people have immunity to measles through vaccination, so the overall risk to the public remains low.

The state health department was consulted in the decision to declare the outbreak.

Previously, the health department disclosed that an adult and two children from the same family were contagious between December 27, 2025, and January 1, 2026, while visiting King and Snohomish counties.

During that time, they visited several locations where exposure could have occurred:

• McDonald’s in Everett on 530 128th St. SW (Dec. 27 between 1-3 p.m.)
• Slavic Christian Church Awakening in Mukilteo (Dec. 28 between 2-6:30 p.m.)
• Flying Squirrel Trampoline Park on SE Everett Mall Way (Dec. 29 between 11 a.m.-2 p.m.)
• Chick-fil-A in Marysville on 8810 36th Ave (Dec. 29 between 1-3 p.m.)
• Mukilteo-Clinton Ferry (Dec. 30 between 1-3 p.m.)
• Fisherman Jack’s on 1410 Seiner Dr. in Everett (Dec. 30 between 6-9:30 p.m.)
• Rental car shuttles to and from the airport and the Consolidated Rental Car Facility at 3150 S 160th, SeaTac (Jan. 1 between 6 a.m. and 9 a.m.)
• Seattle-Tacoma International Airport N Concourse (Gate N4) + Green Train Line (Jan. 1 from 7 a.m. to 11:15 a.m.)

For the current outbreak involving local children, officials suspect exposure may have occurred at:

• Jan. 8, 2026, 12:30 p.m. to 2 p.m. – Stellar Kids Dentistry (111 SE Everett Mall Way, Everett WA 98208)
• Jan. 9, 2026, 8:30 a.m. to 5:15 p.m. – Pathfinder Kindergarten Center (Mukilteo School District), 11401 Beverly Park Rd, Everett, WA, 98204
• Jan. 9, 2026, 8:30 a.m. to 5:15 p.m. – Serene Lake Elementary School (Mukilteo School District), 4709 Picnic Park Rd in Everett, WA, 98026
• Jan. 13, 2026, 1:10 p.m. to 3:10 p.m. – Swedish Mill Creek Campus medical facility, 13020 Meridian Ave. S., Everett, WA, 98208

It’s important to note that measles can spread before individuals are aware they are infected, even before any rash appears.
