The number of confirmed and probable mumps cases at the University of Missouri has grown to 228.
The University of Missouri released the latest numbers Wednesday as students take finals before heading home for winter break.
Health officials say they plan to continue monitoring cases over the break and through January. The school also is recommending that students receive a third dose of a vaccine that protects against mumps, as well as measles and rubella.
The school says most of the sickened students have recovered, with at least 190 of them no longer infectious.
Mumps is a viral infection that causes swelling in the salivary glands and cheeks. The university is among several across the nation that has grappled with outbreaks this year.
