What Is MRSA?
Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that causes infections in different parts of the body. It's tougher to treat than most strains of staphylococcus aureus -- or staph -- because it's resistant to some commonly used antibiotics.
Symptoms:
The symptoms of MRSA depend on where you're infected. Most often, it causes mild infections on the skin, like sores or boils. But it can also cause more serious skin infections or infect surgical wounds, the bloodstream, the lungs, or the urinary tract.
,MRSA is sometimes called a "super bug."
What Causes MRSA?
Garden-variety staph are common bacteria that can live in our bodies. Plenty of healthy people carry staph without being infected by it. In fact, one third of everybody has staph bacteria in their noses.
Who Gets MRSA?
MRSA is spread by contact. So, you could get MRSA by touching another person who has it on the skin. Or you could get it by touching objects that have the bacteria on them. MRSA is carried by about 2% of the population (or 2 in 100 people), although most of them aren't infected.
MRSA infections are common among people who have weak immune systems and are in hospitals, nursing homes, and other health care centers. Infections can appear around surgical wounds or invasive devices, like catheters or implanted feeding tubes. Rates of infection in hospitals have been steadily declining since 2005. Rates of community-associated MRSA, or infection of healthy people who have not been hospitalized, have also decreased since 2005.
