Although mumps was once considered a universal childhood disease in the United States, routine mumps vaccination had led to a >99% reduction in cases by the early 2000s. However, since 2006, there has been an increase in mumps cases in this country, the majority among fully vaccinated persons. Mumps should be suspected in all patients with parotitis or mumps complications (see “Clinical Manifestations”), regardless of age, vaccination status, or travel history.
