Community-associated MRSA: new guidelines for a new age.

摘要

Methicillin-resistant Staphylococcus aureus (MRSA) has become very common in communities. It is such a common occurrence, that some primary care providers (PCPs) tend to treat patients as MRSA-positive until proven otherwise. Most patients diagnosed with MRSA are healthy, young adults with no risk factors for immunocompromise.A major cause of the development of antimicrobial resistance is the extensive use of antimicrobialcommon in children less than 2 years of age than with any other age group.The most common presentations of CA-MRSA skin infections are abscesses, cellulitis, folliculitis, and impetigo; cellulitis and abscesses are the most common. An increase in necrotizing fasciitis and myositis from CA-MRSA was also noted. Necrotizing fasciitis attacks the already immunocompromised host.
