Methicillin-resistant Staphylococcus aureus (MRSA) emerged in the late 1980s and is a leading cause of skin and soft-tissue infections (SSTIs) in the United States.1 Unlike hospital-associated MRSA strains, community-associated MRSA strains, commonly designated USA300 by use of pulsed-field gel electrophoresis, initially were found in children without health care exposure. These strains of community-associated MRSA now cause infections in community and hospital settings.2 Recent data from the Centers for Disease Control and Prevention showed that the number of cases of invasive community-associated MRSA infection increased among children between 2005 and 2010.3 Noninvasive MRSA infections far outnumber invasive MRSA infections among children and can lead to a significant economic burden.
