Mumps is an infection caused by a virus. It is contagious and spreads easily through the air when an infected person coughs or sneezes. The mumps vaccine is the best way to prevent it. Most people fully recover from mumps completely in a few weeks. However, mumps can be serious and cause complications like hearing loss, miscarriage, or swelling of the reproductive organs, brain and the tissue that covers the brain and spinal cord.
