Increased incidence of invasive group a streptococcal disease in Ireland, 2012 TO 2013

Abstract

Invasive group A streptococcal (iGAS) infections have been notifiable in Ireland since 2004. Incidence rates (2004-2011) have ranged from 0.8 to 1.65 per 100,000. In 2012, the iGAS rate rose to 2.66 per 100,000 and was associated with a high proportion of emm1 isolates. A further increase in January to June 2013 has been associated with increased prevalence of emm3. Public health departments and clinicians have been alerted to this increase. © 2007-2013.
