Mumps is a (usually) self-limited viral infection that often occurs in epidemics among children. Its incidence has markedly diminished in countries with childhood vaccination programs, but can still be seen in patients who have not received vaccinations or who have waning immunity.
Patients often present with nonspecific viral symptoms of fever, myalgias, and malaise. More specific features include facial swelling (parotitis) in 95% and/or testicular pain (orchitis).
Serum IgM antibody testing can be used to confirm a case of mumps, if necessary.
Mumps is a single-stranded RNA paramyxovirus 2.
Mumps typically results in classic clinical signs and symptoms, some of which can be supported through radiological features:
- mumps parotitis
- viral meningitis and/or encephalitis 3
- epididymo-orchitis 4
- pancreatitis (uncommon)
History and etymology
The word "mumps" arises from the 1500s, and derived from a word variably used to mean "to grimace" or "to whine".
