Mukilteo school sees first case of mumps

Challenger Elementary case part of statewide outbreak

A Challenger Elementary School student who has a probable case of the mumps is being kept out of school until no longer contagious.

Principal Dirk Adkinson sent a letter from the Snohomish Health District home with students March 30 acknowledging the situation and offering basic information about the mumps.

This represents the only known case of the mumps in the Mukilteo School District, though it is considered part of a statewide outbreak that began in November 2016.

Some 155 cases were recorded in 2016, compared with seven in 2015, according to the state Department of Health. In 2017, some 694 cases have been recorded as of March 29.

As of April 3, Snohomish County has recorded 47 cases – 18 confirmed and 29 probable. Of those, 33 cases are attributed to students in county schools, including 15 at Everett High School, with 5 confirmed and 10 probable.

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.

Out of an abundance of caution, the Snohomish Health District has recommended excluding students with no doses or one dose of MMR from attending school until the 26th day past possible exposure.

All affected school districts have contacted staff and families of the affected students, according to the district. As soon as unvaccinated and under vaccinated students receive the MMR, districts 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.
