A Mumps Outbreak is Affecting Hundreds in Washington State

Due to a mumps outbreak, students in some Washington state counties are being told to stay home if they are not up to date on their vaccinations. Health officials urge people to take precaution and get immunized to help stop the spread of mumps.
As of Feb. 1, there have been 349 reported cases of mumps in Washington across eight counties. The largest outbreaks are in King County (173 cases) and Spokane County (123 cases), and many of the cases are in school-aged children.
Mumps is a contagious disease that spreads through saliva, and causes muscle pain, fatigue, loss of appetite and low-grade fever. The disease can also lead to meningitis, encephalitis and even hearing loss.
In 2016, the U.S. reported 5,311 cases of mumps in total, the highest since 2006. But this pales in comparison to before the U.S. mumps vaccination program started in 1967 where around 186,000 cases were reported each year.
