Mumps cases are growing in number beyond the cases currently at the University of Missouri. The number of confirmed mumps cases at the University of Missouri is growing amid a national rise in cases. The university plans to provide an update each Wednesday. As of Nov. 9, the university had recorded 17 cases since the beginning of the fall semester. The school says all the students received the required two doses of a vaccine that protects against mumps, as well as measles and rubella. Mumps is a viral infection that causes swelling in the salivary glands and cheeks. Anyone with symptoms is asked to stay at home. The Centers for Disease Control and Prevention says 2,345 mumps cases had been reported nationwide as of last month. That’s more than twice as many as in all of 2015. Other universities also have reported cases, including Harvard.
