Inflammation of the tonsils to recurring fever for a few days depends mainly on the physical condition of the patient, the virulence of the causative microorganisms, and whether timely and standardized treatment is provided. Most patients with tonsillitis have a recurring fever for 3 to 5 days, usually not more than a week. Inflammation of the tonsils is mainly caused by infection with Streptococcus b hemolyticus, a bacterial infection that causes redness, swelling and suppuration of the tonsils. If the bacterial infection persists and inflammatory factors continue to be released, the fever may recur for a longer period of time. If the inflammation of the tonsils is mild, the congestion of the tonsils is not obvious, and the recurrent fever lasts for a relatively short period of time.
