Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections have emerged as a significant issue in some Indigenous communities (including First Nations, Inuit and Métis) in Canada. Primarily associated with skin and soft-tissue infections, this organism can also result in significant morbidity and mortality. Canadian and American guidelines for managing CA-MRSA infections have been published. The specific epidemiology, microbiology and susceptibility patterns, and the social/environmental circumstances of CA-MRSA infections in Indigenous communities need to be considered for strategies to reduce transmission. While reducing household crowding and improving in-home potable water supply are optimal strategies to reduce the impact of this illness, implementing Canadian guidelines along with increased prevention strategies are recommended as interim measures.

monitor resistance• Collect specimens for culture from purulent drainage of abscesses to monitor resistance patterns and guide empirical management.
be advocates• Get involved with efforts to improve in-home potable water services and housing conditions for Indigenous and other marginalized populations, at both the federal and provincial/territorial government levels. (For information on advocacy approaches, see ).
ensure prevention• Use evidence-based guidelines to reduce unnecessary antibiotic use and provide educational materials to families about appropriate antibiotic use. For patient information, visit or .• Practice and promote hand hygiene, starting with young children.• Encourage seasonal influenza vaccination for all children. There is added benefit in MRSA endemic communities because of the risk for severe MRSA pneumonia following an influenza infection.
Practice infection control in health centres and clinics• Model and reinforce proper hand hygiene before and after each completed patient contact by all staff and volunteers.• Make alcohol-based handwashing supplies easily available wherever sinks and running water are less accessible.• Implement routine infection control practices in health centres and appropriate preventive measures following the assessment of a client with an MRSA infection.
Use management strategies• Engage community health staff, clients and communities in preventive approaches.• Educate patients and families about how to manage MRSA SSTIs, including:• Keeping wounds covered with clean dry bandages; if unable to cover, exclude from contact sports or child care unti...
