Abstract

In this report, we summarize the results of surveillance, on-site assessments, and molecular analysis conducted as part of a group A Streptococcus outbreak investigation in 2 skilled nursing facilities. We identified cases in 24 individuals (6 deaths) and infection prevention deficiencies. Isolates from 14 individuals represented the globally emergent clade 3 emm89 strain. Molecular analysis suggests that the 2 outbreaks were related. Wound care practices and 1 symptomatic shared employee may have facilitated transmission. Strict adherence to infection prevention practices is needed to prevent group A Streptococcus transmission.

Keywords: Clade 3 emm89; Health care personnel; Infection prevention; Long-term care; Wound care.
