Age differences in the etiology of angina and acute pharyngitis. In the first 4-5 years of life, acute tonsillitis / tonsillopharyngitis and pharyngitis are mainly viral in nature and are caused most often by adenoviruses, in addition, the viruses of herpes simplex and enteroviruses Coxsackie can cause acute tonsillitis / tonsillopharyngitis and acute pharyngitis.
Since the age of 5, the B-hemolytic streptococcus of group A (S. Pyogenes), which becomes the leading cause of acute tonsillitis / tonsillopharyngitis (up to 75% of cases) at the age of 5-18 years acquires great importance in the onset of acute tonsillitis . Along with this, the causes of acute tonsillitis / tonsillopharyngitis and pharyngitis can be streptococci of group C and G, M. Pneumoniae, Ch. Pneumoniae and Ch. Psittaci, influenza viruses. Significantly less often, Staphylococci, fungi of the genus Candida and other microorganisms act as pathogens. Anaerobes (necrotic angina of Simanovsky-Plaut-Vincent) in children are fairly rare.
Tonsillitis / tonsillopharyngitis and pharyngitis, in addition, may be one of the manifestations of infectious diseases such as diphtheria, scarlet fever, tularemia, infectious mononucleosis, typhoid fever, HIV infection (so-called secondary tonsillitis / tonsillopharyngitis).

Often they are accompanied by the appearance of raids on the tonsils and the back wall of the pharynx.
