Abstract

Four group A streptococcus (GAS) bacteraemia occurred in a small burn unit within 2 weeks. The GAS patient isolates, characterized as emm89, shared the same PFGE pulsotype with two other strains isolated 2 months later. The outbreak investigation revealed that a nurse was the most likely source of GAS transmission, as she was confirmed to carry the same outbreak strain in her throat and had direct and regular contact with the six outbreak patients in the unit. The outbreak was controlled after the nurse had undergone eradication treatment. This report highlights the emergence of the emm89 clone and its capacity to elicit invasive GAS outbreaks.
