MU confirms additional cases of the mumps

The University of Missouri in Columbia confirmed that 13 more students have been diagnosed with the mumps on Thursday.

The announcement raises the total number of MU students infected by the virus to 17.

Last week, Mizzou announced four students had been diagnosed with the mumps, and the school was awaiting test results for five others.

According to the MU News Bureau, all of the students infected had received a mumps vaccine.

University officials told ABC 17 News that they’re working with local and state healthcare workers to stop the spread of the virus, which is transmitted through respiratory droplets.

It can take up to three weeks before symptoms of the mumps show up. Symptoms can include swelling of the jaw, fever and aches.

The Centers for Disease Control and Prevention reported in October the number of mumps cases in the U.S. is up from 2015. There were 1,057 cases reported last year.

In 2016, 2,345 cases have been reported in 45 states.

MU students who believe they’re infected with the mumps are advised to call the health center at 573-882-7481, or their medical provider.
