Two days ago, my son had mumps. What is the reason?

Mumps occurs due to a variety of factors, and the causes vary depending on the classification. If it is epidemic mumps, it is caused by mumps virus; if it is obstructive mumps, it is caused by an explanation in the parotid duct, or repeated attacks of inflammation. In addition, acute suppurative mumps is caused by a patient who has abdominal surgery, cannot eat, and does not clean his mouth.
