Two new measles cases have been confirmed in Stevens County, separate from the case first identified on February 2, 2026, bringing the county's total to three, according to the Northeast Tri County Health District.
In the two new cases, health officials say the individuals were not in Stevens County during their infectious period, meaning there is no known local exposure risk. In the first new case, the individual followed public health guidance and took precautions to limit contact with others, and no close contacts or public locations with possible exposure have been identified.
"In the current local scenario, we do not currently have any evidence that measles is spreading in public locations in Stevens County, but we are monitoring closely," said Dr. Sam Artzis, Northeast Tri County Health District Health Officer.
As of the date of the announcement, Washington State had reported 23 confirmed measles cases statewide. Of those, 18 involved people younger than 18 years old and 5 involved adults. Twenty-one of the 23 cases were in unvaccinated individuals, with 2 cases listed as unverified vaccination status.
Health officials urge residents to stay up to date on the MMR (measles, mumps, and rubella) vaccine, which is about 97 percent effective after two doses. Residents with questions about their vaccination status can contact their health care provider or access records through the state's My IR Mobile system at myirmobile.com.
