Purulent tonsillitis refers to the acute purulent infection of the tonsils, mainly caused by bacterial infections, including Staphylococcus aureus, hemolytic streptococcus, etc. The clinical symptoms of purulent tonsillitis are quite obvious and relatively severe. However, generally, purulent tonsillitis is not treated in the hospital nowadays, but treated in outpatient settings with oral antibiotics or intravenous infusions for anti-infection treatment. Clinically, unless purulent tonsillitis is complicated by other diseases, such as peritonsillar abscess, pharyngeal abscess, or retropharyngeal abscess, hospitalization may be considered for treatment.
