Distribution of variants in laboratory-diagnosed invasive group A streptococcal infections, Denmark, January 2018–February 2023 (n = 1,019)
DK: Denmark; EMM: the M protein; iGAS: invasive group A Streptococcus; ST: sequence type; UK: UK.
The most prevalent sequence types are listed, and M1 (ST28/EMM-1.0) isolates have been further subtyped into three lineages. Isolates marked ‘No data’ are from cases without whole genome sequencing data. Variant type is determined by in silico multilocus sequence typing and core genome single nt polymorphism analysis.
