Blunt Trauma as a Risk Factor for Group A Streptococcal Necrotizing Fasciitis

摘要

PurposeAnecdotal reports suggest that blunt trauma and seemingly innocuous musculoskeletal injuries (e.g. muscle strains) are risk factors for developing necrotizing fasciitis (NF) and myositis caused by group A Streptococcus and other bacteria; however, this hypothesis has not been tested in analytic epidemiologic studies of invasive group A streptococcal (GAS) disease. We conducted two case-control studies to determine whether nonpenetrating trauma is a risk factor for either NF or severe cellulitis caused by GAS.
