Comparison of incidence of bloodstream infection with methicillin-resistant Staphylococcus aureus between England and United States, 2006-2007.

We compared incidence of methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infection (BSI) in the United States and England by using population-based surveillance. The incidence of community-onset MRSA BSI was 6.3-fold higher in the United States than in England, whereas the incidence of hospital-onset MRSA BSI was similar between the 2 countries.
