Reemergence of Streptococcus pyogenes Infections in a Large Italian Hospital: A déjà vu from past Years.

Abstract

At the end of 2022 and in the following months, an increase in the incidence of Streptococcus pyogenes infections was observed in many European countries that was simultaneously accompanying to enhance of invasive infections (iGAS). We have showed a risen trend of S. pyogenes infections among preschoolers after the pandemic event. A thorough epidemiological investigation of both paediatric and adult samples positive for S. pyogenes indicate a more complex scenario leading to need of important improvement in surveillance programs.
