Carbuncle in Adult
Methicillin-resistant Staphylococcus aureus (MRSA) first emerged as an important nosocomial pathogen in the 1960s. In more recent years, community-acquired outbreaks of MRSA have been described increasingly among prisoners, military recruits, athletes, intravenous (IV) drug users, and men who have sex with men. Community-acquired MRSA (CA-MRSA) has also been identified in otherwise healthy individuals lacking these risk factors. In a recent study of emergency department visits for purulent skin and soft tissue infections, MRSA was identified as the etiologic agent in the majority (59%) of cases. Furthermore, this study determined that 57% of patients with MRSA did not receive the appropriate initial antibiotic therapy.
