Expansion of invasive group A Streptococcus emm1 and the M1UK lineage in Canada, 2018–2023. A) Number of emm1 isolates collected, by quarter. B) Percentage of M1UK isolates among emm1 isolates collected. Q1, January–March; Q2, April–June; Q3, July–September; Q4, October–December. Annual proportions of emm1 are listed above the bars. Intermediate indicates an isolate with a partial M1UK genotype; not sequenced indicates an isolate that was submitted to the National Microbiology Laboratory as line-listed typing data only.
