SNOHOMISH COUNTY, Wash. — The Snohomish County Health Department has confirmed three new cases of measles connected to children who were exposed to a contagious family who was visiting from South Carolina.
According to the health department, three new cases constitute an outbreak, “a sign the disease is now spreading locally.”
The children tested positive for the virus that causes measles on Wednesday, Jan. 14.
The health department said these children had experienced fever, cough and rashes consistent with measles.
They were not vaccinated.
“We’re expecting more measles cases as a result of the previous exposures as well as these new outbreak cases,” said Snohomish County Health Officer Dr. James Lewis. “We are hoping to contain it, but unfortunately there have been a number of exposure sites already and there are likely more cases in the community that we do not know about yet.”
The health department said that most people have immumnity to measles through vaccination, so the risk to the general public is low.
The state health department was consulted before the “outbreak” was declared.
Last week, the health department announced that one adult and two children in the same family were infectious from Dec. 27, 2025, through Jan. 1, 2026, while visiting King and Snohomish counties from South Carolina.
