The tonsils are the lymphoid tissue of the pharynx and are an important part of the endopharyngeal lymphatic ring. There are several larger lymphoid tissue masses under the mucosa of the pharynx, namely the pharyngeal tonsils, palatine tonsils, and lingual tonsils. The largest, the palatine tonsil, is customarily called the tonsil. The tonsils have some immune function during childhood. The tonsils contain various phagocytic cells, which can also produce cells and antibodies of natural immunity, and have active defense against harmful substances that invade the body from blood, lymph or other tissues. Because of the above-mentioned immune function of children’s tonsils and their young age, they are vulnerable to stimulation by various pathogens and inflammation of the tonsils. Acute tonsillitis is an acute non-specific inflammation of the palatine tonsils. If it is a viral infection, there is no special antiviral drug treatment, but mainly symptomatic treatment. You can take pediatric cold and flu flush to relieve symptoms, and if there is a fever, you can take antipyretic flush. If the infection is secondary to bacterial infection leading to acute purulent tonsillitis, it needs to be treated with antibiotics, preferably penicillin or cephalosporin antibiotics. If the tonsillitis is recurrent and acute, with more than five recurrent attacks in two years or more than seven recurrent attacks in one year, tonsil removal surgery is required. During acute tonsillitis, due to viral infection, which is contagious for a longer period of time, isolation, bed rest, and fluid or semi-liquid food are required. Avoid systemic complications.
