Mumps is a disease caused by a virus. It typically starts with a few days of fever, headache, muscle aches, tiredness, and a loss of appetite. Then a person with mumps may develop swollen cheeks or jaw.
Most people with mumps get well in a few weeks. Some people who get mumps may have a mild illness or may not even know that they have the disease. However, mumps can occasionally cause serious health problems, especially in adults. These health problems can include swelling of the brain or deafness.
