Methicillin-resistant Staphylococcus Aureus (MRSA) is a type of staph bacteria that is resistant to certain antibiotics. Most MRSA infections are skin infections that may appear as pustules or boils which often are red, swollen, painful, or have pus or other drainage. They often first look like spider bites or bumps that are red, swollen, and painful. These skin infections commonly occur at sites of visible skin trauma, such as cuts and abrasions, and areas of the body covered by hair (e.g., back of neck, groin, buttock, armpit, beard area of men). But in healthcare settings, MRSA can cause more severe and potentially life-threatening infections, such as bloodstream infections, surgical site infections, or pneumonia. Bridget Boudreaux, RN, CBN, infection preventionist at Memorial Hospital, discusses the signs and symptoms and prevention of MRSA.
