The Midwest is dealing with an outbreak of the mumps. There have already been more than 80 confirmed cases in Illinois -- three times the number of cases across the state all of last year. Schools districts have been sending out warnings to parents about student cases. In Central Ohio health officials are reporting more than 320 cases, nearly 200 of them linked to Ohio State University. The CDC says outbreaks in at least two U.S. universities have contributed to these cases -- Ohio State and Fordham University in New York. Health officials say mumps outbreaks when they occur often do so in winter and spring, and that a major factor in mumps outbreaks is being in a crowded environment,such as attending the same class or living in a dormitory with someone who has it. Public health officials says mumps is spread by droplets of saliva or mucus from the mouth, nose or throat, usually when someone coughs, sneezes or talks, and that Items used by an infected person, such as cups or soft drink cans, also can be contaminated with the virus.
