Chronic tonsillitis is a chronic inflammatory disease of the tonsils, mainly due to repeated attacks of acute tonsillitis or the presence of a chronic infectious focus in the teeth and oral cavity, which prevents acute tonsillitis from being actively cured and then gradually develops and prolongs into chronic tonsillitis. Since it is a chronic inflammation, it should be noted that it generally is not contagious. Even acute tonsillitis has relatively weak contagiousness. In clinical treatment, chronic tonsillitis is mainly treated symptomatically with traditional Chinese medicines that clear heat and detoxify. In summary, chronic tonsillitis is not contagious.
