Mumps
Mumps is an infection caused by a virus. It is highly contagious and passes easily from person to person, so prevention is very important. The mumps vaccine is the best way to prevent it. Although most people fully recover from mumps within 7 to 10 days, in rare cases the virus may cause complications.
