There is no treatment for mumps, but the measles-mumps-rubella (mmr) vaccine can prevent it.before the routine vaccination program in the United States, mumps was a common illness in infants, children and young adults. Now it is a rare disease in the United States Centers for Disease Control and Prevention.
