CHAMPAIGN, Ill. -- University of Illinois officials say nine students on the Urbana-Champaign campus have been diagnosed with mumps. The cases are part of an outbreak that has already produced more cases this year than the state saw in all of 2013.
Dr. Robert Palinkas is director of the campus McKinley Health Center. He tells The News-Gazette the nine cases have all been diagnosed since spring break. A faculty member has what may be a 10th case.

Palinkas said the students were all vaccinated. But he said the vaccine is only 80 to 85 percent effective.
The Illinois Department of Public Health says 65 other cases have been confirmed this year. Most are in Morgan and Sangamon counties in central Illinois.
Last year the state had a total of 26 mumps cases.
