Deadly skin infection? 12 graphic photos that could save your life

Think boils and blisters are no big deal? Think again. Some seemingly minor skin problems are caused by MRSA, potentially lethal staph germs that are resistant to some antibiotics.

The key to successful treatment of a MRSA (methicillin-resistant Staphylococcus aureus) infection is prompt treatment. That's why it's so important to know all about MRSA - what causes it, how it's treated, and - perhaps most important - what MRSA skin infections look like.

What does a MRSA skin infection look like? Typically, it's a bump, boil, pustule, or infected area that is red and swollen and full of pus. It may be painful and warm to the touch, and accompanied by a fever.

Sometimes MRSA lesions are mistaken for spider bites.

Is the lesion "purulent?" That is, is it movable, compressible, and fluid-filled? Does it have a yellow or white center, with a central point or "head?" Is it draining pus? Those are all signs of a MRSA skin infection.
