Mumps is a contagious viral disease that is transmitted through saliva and causes swelling of the salivary glands. Symptoms include fever, fatigue, and swelling of the parotid glands near the ears. While most people recover within 2 weeks with rest and over-the-counter pain medication, rare complications can include meningitis, encephalitis, hearing loss, and sterility in males. Vaccination with 2 doses of the MMR vaccine provides effective protection against mumps.
