Post-pandemic upsurge in Group A <i>Streptococcus</i> infections at an Italian tertiary university hospital

<i>Streptococcus pyogenes</i> (GAS) is a narrow-spectrum pathogen, circulating only in humans. Following the loosening of various public health measures implemented to face the challenge of the COVID-19 pandemic, a significant rise in GAS cases has been observed. Our study revealed a significant rise in GAS cases, particularly invasive infections, over the last two years. Genomic analysis identified multiple sequence types, including isolates belonging to an emerging lineage named M1<sub>UK</sub>. These findings underscore the importance of ongoing surveillance and genomic monitoring of GAS infections, especially considering their rising incidence and severity. Public health strategies should consider not only microbe-associated aspects but also host-associated and external factors to effectively address this resurgence and prevent future outbreaks.

Abstract

<i>Streptococcus pyogenes</i> (GAS) is a narrow-spectrum pathogen, circulating only in humans. Following the loosening of various public health measures implemented to face the challenge of the COVID-19 pandemic, a significant rise in GAS cases has been observed. Our study revealed a significant rise in GAS cases, particularly invasive infections, over the last two years. Genomic analysis identified multiple sequence types, including isolates belonging to an emerging lineage named M1<sub>UK</sub>. These findings underscore the importance of ongoing surveillance and genomic monitoring of GAS infections, especially considering their rising incidence and severity. Public health strategies should consider not only microbe-associated aspects but also host-associated and external factors to effectively address this resurgence and prevent future outbreaks.
