"Staph" or Community-Associated Methicillin-Resistant Staphylococcus aureus (CAMRSA) Information

Basic Facts and Background

Staphylococcus aureus, commonly referred to as “Staph,” are bacteria found in the nose or skin. Staph are the most common cause of skin infections. Some Staph have developed resistance to the most common family of antibiotics that treat skin and blood infections. These Staph are called methicillin (antibiotic)-resistant Staphylococcus aureus (MRSA). MRSA infections are common in hospitals and other healthcare settings, like dialysis centers or nursing homes. MRSA infections in hospitals often affect the very old and the very young or the very sick. However, recently MRSA infections have been found in healthy people outside of the hospital. Most of these MRSA infections are found in the skin and soft-tissue (muscle, fascia, fat). Since they occur in people in the community, they are referred to as community-associated MRSA (or CAMRSA) infections.

CAMRSA is clinically and genetically different from MRSA infections that people acquire in healthcare settings. The information below should help consumers and healthcare professionals understand CAMRSA as a new and emerging disease.
