Surveillance of Staphylococcus aureus infections in 3 northern remote communities of Saskatchewan was undertaken. Rates of methicillin-resistant infections were extremely high (146–482/10,000 population), and most (98.2%) were caused by USA400 strains. Although USA400 prevalence has diminished in the United States, this strain is continuing to predominate throughout many northern communities in Canada.

Over the past decade, community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections have rapidly emerged in Canada (1). These CA-MRSA strains are causing infections in often young otherwise healthy persons with no traditional health care–associated risk factors (2), linked with increased illness severity and deaths (3), and now entering and being disseminated within health care facilities (4). In comparison to the incidence of CA-MRSA infections in large urban centers across Canada, which has been addressed through the ongoing efforts of the Canadian Nosocomial Infection Surveillance Program (1), little attention has been directed at the emerging problem of CA-MRSA or CA-methicillin-susceptible S. aureus (MSSA) in rural and northern communities of Canada. In this study, active surveillance was undertaken in 3 remote northern communities to assess the prevalence and effects of MRSA and MSSA infections.
