Invasive group A streptococcal disease: Management and chemoprophylaxis.

Reporting of severe invasive group A streptococcal disease (IGAS) has increased in Canada over the past decade, highlighting the importance of optimal chemoprophylaxis and management strategies. Canadian guidelines have had variable uptake across Canada. This practice point updates relevant aspects of these guidelines, with a focus on chemoprophylaxis of contacts of IGAS cases and clinical management of IGAS. The importance of penicillin in treating group A streptococcal disease is reaffirmed, and the role of clindamycin is discussed. In situations in which chemoprophylaxis may be considered, preferred agents are summarized.
