At the time, 50 cases of mumps had been reported in the entire state of Iowa,  as stated by KCGR-TV9. There are now more than 100 students that have been diagnosed with the virus, reports the Gazette.

The University of Iowa requires two doses of the MMR  vaccine, but are now also offering a free booster shot to students, as released on their Student Health and Wellness web page.
