Q: (CNN) The United States is being hit with the most mumps cases in a decade, according to the Centers for Disease Control and Prevention. The latest tally as of November 5 is 2,879 cases in 45 states and the District of Columbia. Mumps is a contagious disease caused by a virus spread through saliva and mucus.
