Acute suppurative parotitis is common when the patient’s systemic immunity decreases dramatically, such as severe systemic disease, severe upper respiratory tract infection, often with unilateral onset, and less often with simultaneous bilateral onset. The parotid area is visibly swollen and the skin is red; the parotid duct opening is visibly red and swollen, and pus can be seen overflowing from the duct opening by light pressure on the parotid area; the patient has severe systemic symptoms and the temperature can be as high as 40 degrees or more, and the total white blood cell count is significantly elevated in routine blood tests, which is due to bacterial infection; the blood amylase content test is within the normal range. Acute suppurative mumps can be transformed into chronic suppurative mumps. Some mumps do not show an obvious acute inflammatory process, and the skin redness and swelling is not obvious in the chronic phase, which can be repeated with mild swelling symptoms and a slightly higher or normal body temperature. The mumps is a contagious viral infection that occurs in children between the ages of 5 and 15 years old, with a history of contact with other patients before the onset of the disease. The clinical manifestations are mainly swelling and pain in the parotid gland, with an elevated temperature of over 40 degrees, but no redness or swelling of the parotid ducts in the mouth, with saliva flowing out of the ducts without pus.
