Mumps is a contagious viral infection that can cause painful swelling of the salivary glands, especially the parotid glands (between the ear and the jaw). Some people with mumps won't have gland swelling. They may feel like they have a bad cold or the flu instead.
The mumps vaccine protects against the illness. This vaccine is part of the MMR (measles, mumps, and rubella) and MMRV (measles, mumps, rubella, and varicella [chickenpox]) vaccines. Most children get the vaccine as part of their regular shots. Before the mumps vaccine existed, mumps was a common childhood disease in the United States and Canada.
