Skin and soft tissue infections are a common reason for consultation in primary health care centers. Data from the local epidemiology of these infections are rare, but Staphylococcus aureus and Streptococcus pyogenes are known to be the major etiologic agents. The appearance in recent years of community-originated strains of methicillin-resistant S. aureus and erythromycin-resistant pyogenes raises controversy in the choice of initial empirical treatment. This national consensus is for pediatricians, dermatologists, infectiologists and other health professionals. It is about clinical management, especially the diagnosis and treatment of community-originated skin and soft tissue infections in immunocompetent patients under the age of 19.
