Mumps (Epidemic Parotitis)

★ CMTO Exam Focus

Mumps is an acute systemic viral infection caused by the Mumps virus (paramyxovirus family), characterized by painful swelling of one or both parotid glands (parotitis). Spread through respiratory droplets and direct contact with saliva, mumps is typically self-limiting in children but can cause serious complications in post-pubertal individuals including orchitis (20-50% of males), oophoritis, meningitis, encephalitis, and sensorineural deafness. Outbreaks continue in incompletely vaccinated populations.

Recognition

  • Prodrome (1-2 days): Low-grade fever, malaise, headache, myalgia, loss of appetite
  • Parotitis: Painful swelling anterior to and below the ear (parotid region), pushing the earlobe upward and outward. May be unilateral initially, becoming bilateral in ~70%
  • Fever: Typically 38-40C. Peaks with parotid swelling
  • Incubation: 16-18 days (range 12-25 days)
  • Contagious period: Several days before parotitis through 5 days after swelling onset
  • Distinguishing feature: Mumps swelling is anterior to the ear and pushes the earlobe up. Cervical lymphadenopathy is below the jaw
  • Orchitis signs: Testicular pain, swelling, and fever occurring 4-8 days after parotitis onset (20-50% of post-pubertal males)
  • Subclinical: 20-30% of infections are asymptomatic but still contagious
  • Reportable disease in Ontario

MT Relevance

  • Systemic contraindication: Acute mumps contraindicates massage — the client is febrile, contagious, and in pain
  • Local contraindication: Even in recovery, the swollen parotid and surrounding cervical region is a local contraindication until fully resolved
  • Return to treatment: Massage may resume once the client is afebrile and all swelling has fully resolved, typically 10-14 days after symptom onset
  • Orchitis awareness: Male clients recovering from mumps orchitis may have residual testicular sensitivity. Avoid abdominal/hip techniques that could cause referred discomfort

Required Actions

  • Refer to a physician immediately if mumps is suspected — reportable disease
  • Do not treat during active infection or while swelling persists
  • Be aware that clients may be contagious before swelling appears (virus is shed in saliva before parotitis onset)

Key Takeaways

  • Mumps is caused by Mumps virus (paramyxovirus). Spread by respiratory droplets and saliva. Incubation 16-18 days.
  • Hallmark sign: painful parotid swelling pushing the earlobe upward and outward.
  • Serious complications in post-pubertal individuals: orchitis (20-50% of males), meningitis, sensorineural deafness.
  • Mumps is a reportable disease in Ontario. Refer immediately if suspected.
  • Acute mumps is a systemic contraindication. Local contraindication to the neck/jaw persists until swelling fully resolves.
