Methicillin-resistant Staphylococcus aureus (MRSA) infection was relatively uncommon in the United States before 1975. From 1975 through 1980, MRSA infection spread to hospitals in previously unaffected areas of the United States, and the number of institutions reporting cases of MRSA infection increased considerably [1]. From 1983 through the early 1990s, the prevalence of health care–associated (HA) MRSA infection increased dramatically, and it continued to increase more gradually during the latter half of the 1990s [2, 3]. In 1998, Herold et al. [4] reported an alarming increase in the occurrence of community-associated (CA) MRSA infection among young children with none of the typical risk factors associated with HA MRSA. Within a few years, CA MRSA strains became widely disseminated, accounting for 15%–74% of S. aureus skin and soft-tissue infections seen in emergency departments [5–8]. A recent population-based study of invasive MRSA infection found that 26.6% of infections had onset during a hospitalization, 58.4% were community-onset infections among individuals with previous health care exposures, and 13.7% were CA infections [9].
