  • Incubation Period: Typically 16-18 days, ranging from 2 to 4 weeks. (ref)
  • Contagious Period: From 1 day before symptoms appear to 14 days after resolution.


  • Seasonality: More common in winter and spring in temperate climates.
  • Pre-Vaccine Era: Frequent epidemics; 90% of infections occurred before age 15.
  • Vaccination Impact: Introduction of the MMR vaccine dramatically reduced the incidence of mumps.
  • Recent Trends: Occasional outbreaks, particularly among vaccinated populations in college settings.

Clinical Features:

  • Subclinical Infections: Approximately 30% of cases.
  • Symptoms: Prodrome of low-grade fever, headache, malaise, followed by painful salivary gland swelling, primarily the parotids.

  • Clinical Presentation: Typical in epidemic settings.
  • Laboratory Tests: Mumps-specific IgM, IgG titer rise, viral culture, and PCR from salivary duct secretions.


  • Management: Primarily supportive; includes analgesics, hydration, and avoidance of sour foods to reduce salivary stimulation.
  • Vaccination: Critical for prevention; two doses of MMR are standard, with discussions on the necessity of a third dose during outbreaks.
