Whole-genome sequencing in the investigation of recurrent invasive group A streptococcus outbreaks in a maternity unit

ConclusionsOccupational health procedures were enhanced, staff were screened, and antibiotic therapy was provided to GAS-positive staff and patients. The definitive source of infection could not be identified, although staff–patient transmission was the most likely route. The pattern of clonal GAS transmission over the four-year study period suggests that long-term persistence of GAS may have occurred.
