Mumps has spread and health officials urge immunization. Please make sure all family members are current with MMR (Measles, Mumps and Rubella) immunizations. State Law requires complete immunizations for school attendance. Those with incomplete immunizations records or exemptions for MMR will excluded from attending school by directions from the local health jurisdiction – if there is a confirmed case of the disease at a school site. The Washington State Department of Health reminds people across the state to take precautions to help stop the spread of mumps.

It is important for all families to take precautions during social gatherings. Avoid kissing, hugging and other close contact with anyone who is suspected of having mumps. If you have been exposed to mumps and feel ill, stay home to help prevent the spread of the disease and contact your healthcare provider. If you don’t have a healthcare provider, call your local health department or the Family Health Hotline at 1-800-322-2588.

What is mumps?

Mumps is a viral illness that can cause fever, headache and swelling of the cheeks and jaw. Most people recover from mumps in a few weeks. In rare cases, mumps can lead to more serious complications that may require hospitalization, including inflammation of the brain and spinal cord and deafness. Up to 30% of people with mumps infection will have no symptoms.

What to do if you have symptoms

If you or your child have symptoms of mumps (fever, headaches, muscle aches, tiredness, loss of appetite & swollen cheeks or jaw), call your healthcare provider. For more information on mumps, including how mumps is spread, who is at high risk of getting mumps, prevention, and more, please visit the Seattle and King County Public Health Insider site.


Best Starts for Kids Survey

King County and the Washington State Department of Health are sending a survey to 12,000 randomly chosen parents and guardians with children in elementary schools across all communities in King County. If you receive a letter in the mail, your child was randomly selected to participate. Staff at Public Health – Seattle and King County and the Department of Community and Human Services partnered with the Washington State Department of Health and public school districts in King County to securely obtain names and parent/guardian contact information for a random sample of children. This only includes children ages 6 months to age 10 or 11 and excludes students whose families have filed FERPA letters with the district. For more information, please visit King County’s website.
