Mumps-CDCreport

An acute viral disease characterized by fever, swelling and tenderness of one or more salivary glands, usually the parotid and sometimes the sublingual or submaxillary glands. Not all cases of parotitis are caused by mumps infection, but other parotitis-causing agents do not produce parotitis on an epidemic scale. As many as 40%–50% of mumps infections have been associated with respiratory symptoms, particularly in children under 5 years. About one-third of exposed susceptible people have inapparent infections; most infections in children under 2 are subclinical.

Mumps can cause sensorineural hearing loss in both children and adults. Pancreatitis, usually mild, occurs in 4% of cases; a suggested association with diabetes remains unproven.
