Inflammation of the tonsils in children may be associated with a variety of factors, including infectious factors, such as bacteria and viruses, immune factors, such as reduced systemic or local immunity, malformed inflammation of adjacent organs, such as acute pharyngitis and rhinitis, secondary to certain acute infectious diseases, such as influenza and measles. Tonsils are part of the lymphatic system of the pharynx, which is the first door of the body to resist external pathogens. When children’s resistance decreases, it can lead to pathogenic bacterial infections, and if children have inflammation of the tonsils, they should be actively treated.
