We report two outbreaks comprising a cluster of 18 group A streptococcal infections across two 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.
Keywords: Cluster; gram positive infection; infection control; post-acute care; whole genome sequencing.
