Of those cases, 33 cases are impacting schools within Everett Public Schools, Lakewood School District, Monroe School District, Mukilteo School District and the Stanwood-Camano School District as follows:
The measles, mumps, and rubella (MMR) vaccine is the best protection against mumps and is highly effective in preventing the virus and reducing outbreaks.

Mumps is highly contagious and can spread easily and quickly in school settings. Keeping students safe and healthy is our primary concern, so that's why we are taking steps to prevent the spread of disease.
All school districts have contacted staff and families of all affected students. As soon as unvaccinated and under vaccinated students receive the MMR, the district will allow them to return to school. Exemptions for personal, medical or religious reasons will be honored, but those claiming exemptions will also be excluded from school or until the 26th day after exposure.
Our schools are ready and well equipped to handle this health issue. An important tool to ensure the health and safety of all district students and staff is to be informed about mumps and important preventive measures. We encourage families to follow up with their health care provider if they have questions or if their child is exhibiting symptoms.
