  • Mumps is spread through direct contact with respiratory secretions or saliva.
  • While you may contract mumps year-round, it is a seasonal disease with peaks in late winter and early spring.
  • People infected with the virus are contagious three days before they begin showing symptoms and up to nine days after they begin showing symptoms.
  • The incubation time of the virus— the time between exposure and the onset of symptoms—is usually 16–18 days.
  • Mumps initially presents with flu-like symptoms, including headache, fever, fatigue, muscle aches, and a loss of appetite.
  • Painful swelling of the parotid salivary glands (located inside the cheek underneath the ears, near the jaw line) is the most prominent symptom of mumps, occurring in 30%–40% of cases.
  • Approximately 20% of those infected with mumps never show symptoms.
  • There is currently no specific treat­ment for mumps.
  • Experts recommend two doses of the measles, mumps, and rubella (MMR) vaccine to most effectively ensure immunization to the virus.
  • Vaccination should ideally be com­pleted during childhood, but may be administered at any age.

Set your own course through any hazard: stay informed, make a plan, build a kit.
