Mumps can be caused by bacterial or viral infections or other factors, and can be treated in dentistry, infectious diseases and other departments, while children can go to pediatrics and be treated accordingly under the guidance of a doctor. The parotid glands are the largest pair of salivary glands and are located on both cheeks near the earlobes. Parotitis can be categorized according to the cause as infectious, such as acute suppurative parotitis and epidemic parotitis, immune, such as Sjögren’s syndrome, or obstructive, such as chronic obstructive parotitis. Acute bacterial parotitis (septic parotitis) is caused by Staphylococcus aureus, Streptococcus, etc. It is often unilateral, with typical manifestations of persistent throbbing pain in the parotid area, obvious swelling centered on the earlobe, and accompanied by high fever. Antibiotics such as penicillin and cephalosporin are needed for treatment; incision and drainage are needed when there is abscess formation. Mumps is a respiratory infectious disease caused by the mumps virus, characterized by non-purulent inflammation of the parotid gland, swelling and pain in the parotid area, and can also cause meningitis, testicular and ovarian inflammation. It mainly occurs in children and adolescents, and can be transmitted through the respiratory tract and other means. Patients should take isolation measures, get plenty of rest, give liquid or semi-liquid diet, and can be treated with antiviral drugs such as ribavirin. To sum up, there are various causes of mumps, you can go to the stomatology department, infection department of the hospital, or pediatrics if you are a child, to clarify the cause of the disease and then standardize the treatment.
