Nationally, as of April 29, 727 mumps cases have been reported to the Centers for Disease Control and Prevention (CDC). In all of last year, 1057 cases were reported.

The federal health agency says in some years, there are more cases of mumps than usual because of outbreaks. Mumps outbreaks can occur any time of year but often occur in winter and spring. A major factor contributing to outbreaks is being in a crowded environment, such as attending the same class, playing on the same sports team, or living in a dormitory with a person who has mumps.
