What is it?
Mumps is an infection caused by a virus. It causes swelling of the saliva (spit) glands most often. Mumps can cause the following complications:
- Meningitis - swelling of the brain and spinal cord with a headache and/or stiff neck
- Orchitis - swelling of one or both testicles; leads to sterility in some rare cases
- Oophoritis - swelling of the ovaries
- Risk of miscarriage in pregnant women, if you are not immune and you get mumps early in pregnancy (first trimester); there is no evidence that mumps causes birth defects
- Hearing loss in one or both ears - may be permanent
- Pancreatitis - usually mild
