MRSA stands for methicillin-resistant Staphylococcus aureus. Staphylococcus aureus is a type of bacteria with lots of different strains.
Many strains of staph bacteria are quite common. Most people have staph bacteria living on their skin or in their noses without causing any problems. If staph bacteria get into a person's body through a cut, scrape, or rash, they can cause minor skin infections. Most of these heal on their own if a person keeps the wound clean and bandaged. Sometimes doctors prescribe antibiotics to treat more stubborn staph infections.
What makes the MRSA different from other staph infections is that it has built up an immunity to the antibiotics doctors usually use to treat staph infections. (Methicillin is a type of antibiotic, which is why the strain is called "methicillin-resistant.")
You can protect yourself and your family by practicing good hygeine (frequent hand washing, etc), covering cut or broken skin until it heals, and by not sharing personal items.
