Mumps is an acute viral illness caused by the mumps virus. Symptoms include fever, headache, muscle aches, tiredness, and loss of appetite, which are followed by swelling of salivary glands. The parotid salivary glands (which are located within your cheek, near your jaw line, below your ears) are most frequently affected.
Severe complications are rare. However, mumps can cause:
-inflammation of the brain and/or tissue covering the brain and spinal cord (encephalitis/meningitis)
-inflammation of the testicles (orchitis)
-inflammation of the ovaries and/or breasts (oophoritis and mastitis)
-deafness, usually permanent
