NASHVILLE, Tenn. (WKRN) – Health officials say there are now at least 278 mumps cases across five counties in Washington State.
The spike is likely tied to a vaccine that can lose its strength over time.
There were more than 100 mumps cases in eight different states in 2016, the most active year for mumps in the U.S. since 2006. Even a student at Belmont University in Nashville was diagnosed.
On Friday, News 2 spoke with Dr. Kelly Moore, the immunization program director with the Tennessee Department of Health, to ask questions and learn more about the mumps.
