§ overviewOverview

Acute systemic viral infection of paramyxovirus (Rubulavirus) with tropism for glandular and nervous tissues.

§ icdICD Classification

B26

§ etiologyEtiology

  • 01Mumps virus (paramyxovirus)

§ epidemiologyEpidemiology

Peak in unvaccinated children 5–15 y; incubation 14–21 d; contagious 1 d before to 5 d after gland swelling.

§ clinicalClinical Features

  • 01Prodrome: fever, malaise, myalgia, headache
  • 02Painful bilateral parotid swelling (70%) with elevated earlobe
  • 03Trismus, pain on chewing acidic foods
  • 04Redness around Stensen duct opening without pus
  • 05Orchitis, oophoritis, meningo-encephalitis, deafness

§ differentialDifferential Diagnosis

  • 01Suppurative parotitis (unilateral, pus at duct)
  • 02Sialolithiasis
  • 03Sjögren syndrome
  • 04HIV parotid disease

§ investigationsInvestigations

  • 01Clinical diagnosis
  • 02Serology: IgM to mumps virus
  • 03RT-PCR of saliva/buccal swab
  • 04Serum amylase elevated (salivary isoenzyme)

§ treatmentTreatment

  • 01Supportive: hydration, analgesia, antipyretics, bed rest
  • 02Isolation for 5 days after swelling onset
  • 03No antivirals of proven benefit

§ complicationsComplications

  • 01Orchitis (30% post-pubertal males) → rarely infertility
  • 02Aseptic meningitis, encephalitis
  • 03Sensorineural deafness (unilateral)
  • 04Pancreatitis

§ prognosisPrognosis

Self-limiting; resolves in 7–10 days; lifelong immunity.

§ preventionPrevention

  • 01MMR vaccine at 12–15 mo and 4–6 y (two doses ≈ 88% effective)

§ examKey Examination Points

  • 01Bilateral parotid swelling with elevated earlobe
  • 02Absence of pus at Stensen duct
