The clinical manifestation is that there is a small mouthwash on the facial skin. When there is clear saliva outflow, the main cause of the disease is damage, which occurs mostly in the parotid gland. And its catheter department, surgical treatment, and high cure rate. Debridement and suture after injury in the parotid gland is the key to prevent this disease. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious Complications: suppurative mumps

Cause
