Acute tonsillitis is one of the most common infectious ENT diseases. Most often we are talking about sore throat, a rapidly developing inflammation of the palatine tonsils. Up to 90% of people have noted its symptoms at least once in their life, and the first episode of the disease often occurs in childhood. A large number of acute tonsillitis is recorded annually, mainly in the cold seasons. But the real incidence is several times higher, since many patients do not consider tonsillitis as a reason to see a doctor and prefer self-medication. But precisely this approach is the main reason for the high prevalence of chronic and complicated tonsillitis.
