Mizzou reports 31 confirmed cases of mumps

COLUMBIA, Mo. -- University of Missouri officials are hoping Thanksgiving break could provide relief from a mumps outbreak that has grown to 31 confirmed and 27 probable cases on the Columbia campus.

The numbers reported Wednesday for the outbreak were almost double the 17 cases that had been confirmed last week. But the good news is students will begin heading home for a weeklong holiday break after classes end today.

"We are hoping that that really alleviates the numbers we are seeing from this particular outbreak," Mary Jo Banken, a spokeswoman for the university, said Thursday. "We are all crossing our fingers on it for sure."

A Centers for Disease Control and Prevention scientist said the exodus of students to their far-flung hometowns for the holiday break shouldn't necessarily pose concerns to those communities.

Dr. Manisha Patel of the CDC's Division of Viral Diseases said Wednesday crowded campus settings, specifically in dormitories, and the common behaviors that take place in those confined conditions -- sharing of bathrooms, dining together, kissing -- promote the transmission of the virus more than household settings.

Patel also said "high coverage rates" nationwide by mumps vaccines will limit the transmission of the virus.

"We've seen that before -- outbreaks on campus, the students go on break, and the outbreak on campus starts to decrease," Patel said. "Once they disperse, that setting of intense exposure no longer is there to keep that virus moving."

The university is among several across the nation -- Harvard and Tufts among them -- that have grappled with mumps outbreaks this year.

All of the students with confirmed or probable cases at Missouri have received the required two doses of a vaccine that protects against mumps, as well as measles and rubella, Banken said.
