This document discusses MRSA (methicillin-resistant Staphylococcus aureus), including what it is, types of infections, risk factors, symptoms, transmission, testing, and treatment. Staph bacteria normally live on the skin but can cause infections when they enter the body through cuts or wounds. MRSA infections are harder to treat because the bacteria are resistant to many common antibiotics. The document outlines hospital-associated and community-associated MRSA infections and provides prevention strategies like hand washing and wound care.
