There have been reports of mumps at the University of Illinois' Urbana-Champaign campus, where more than 100 cases have been confirmed. Two cases were confirmed last month at Eastern Illinois University. Now NIU has a case to add to the tally.

Having mumps is not as common in America. The number of cases ranges from a couple hundred to as many as a couple thousand a year.

What should you look for to determine if you have a case of the mumps? Symptoms include fever, headache, tiredness and swollen salivary glands under the ears.

If sick, stay at home and go see the Doctor.
