What you can do:

The risk to the general public is considered low, as most are immune to measles through vaccination. However, if you are not vaccinated and develop symptoms such as a fever or rash, call your healthcare provider. Do not go in person without calling first.

These recent measles cases reflect a larger spike in measles across Washington and the United States. Snohomish County has documented at least 14 confirmed measles cases in 2026.
