Abstract

Since 2022, the morbidity caused by the group A beta-hemolytic streptococcus (GAS, Streptocossus pyogenes) and the number of fatal cases among children have increased both in Europe and in other parts of the world. The spectrum of the diseases caused by GAS is very wide – from pharyngitis and scarlet fever to life-threatening invasive infections. The reasons for the increase in morbidity are likely to be multifactorial, but largely related to the various measures implemented during the COVID-19 pandemic. The aim of this review was to describe the diseases caused by GAS, as well as their diagnostics and treatment.
