Mumps is an acute, contagious viral illness characterized by the swelling of salivary glands (parotitis). Historically a leading cause of aseptic meningitis and hearing loss in children, widespread vaccination has reduced cases by over 99%, though outbreaks continue to occur in close-contact settings.

Clinical Presentation and Transmission

• Symptoms: The hallmark symptom is parotitis (swelling of the parotid glands at the jaw), which lasts about 5 days. Prodromal symptoms are nonspecific, including low-grade fever, headache, myalgia (muscle pain), anorexia, and malaise. Approximately 15–24% of infections are asymptomatic.

• Transmission: The virus spreads via respiratory droplets and saliva.

• Contagiousness:
