Mumps

Mumps is an acute viral disease caused by the mumps virus that is spread from person to person by coughing or sneezing. People who have mumps may spread the infection to others, even when they do not have any symptoms or their illness is mild.

Prior to the development of vaccination and the introduction of a vaccine, it was a common childhood disease worldwide, and is still a significant threat to health in the third world.

Painful swelling of the salivary glands (classically the parotid gland) is the most typical presentation. Painful testicular swelling (orchitis) and rash may also occur. The symptoms are generally not severe in children.
