We report 2 outbreaks comprising a cluster of 18 group A Streptococcal infections across 2 nursing facilities. Point prevalence surveillance testing identified 8 of 18 cases, and whole genome sequencing validated transmission pathways. Infection prevention interventions at the facility level comprised symptomatic and asymptomatic carriage-based case finding, transmission-based precautions, and treatment to eradicate colonization.
