Community-Associated Methicillin-resistant Staphylococcus aureus (CA-MRSA) Basics
CA-MRSA infections lack traditional health care-associated risk factors. CA-MRSA can cause the same type of infections as other strains of Staphylococcus aureus.
On this page:
- Community-associated (CA) MRSA infections were first recognized in the 1980s.
- Persons with CA-MRSA infections are typically younger and healthier than persons with health care-associated MRSA.
- CA-MRSA bacteria are usually susceptible to more types of antibiotics than are health care-associated strains of MRSA.
- Traditionally, Methicillin-resistant Staphylococcus aureus (MRSA) infections have been associated with hospitalization or other health care-associated risk factors.
- In recent years physicians and other health care providers have observed an increasing number of people with MRSA infections who lack traditional health care-associated risk factors. These people appear to have community-associated infections.
- CA-MRSA infections can cause the same type of infections as other strains of staph.
- Studies conducted in Minnesota have found that CA-MRSA is more likely to cause skin and soft tissue infections and that health care-associated MRSA is more likely to be found in sputum or urine.
