Many European countries have recently reported upsurges in invasive group A (iGAS) infections, mainly caused by 1 , specifically the toxigenic M1 lineage. We present the epidemiology of 1 causing iGAS in Belgium during 2018-August 2023, and describe an emergence of the toxigenic M1 lineage in Belgium in mid-2022 that was observed as an increase in bloodstream infections caused by 1 that continued into 2023.
