- Hospitalized patients are at increased risk for MRSA infection for several reasons:
- Many hospitalized patients are taking antibiotics that can decrease the normal flora found on the body, giving MRSA strains an advantage.
- Many patients in hospitals have breaks in their skin (surgical wounds, intravenous lines (IVs), and catheters) that can allow bacteria to enter underlying tissues or the bloodstream.
- Most infections caused by Staphylococcus aureus are skin and soft tissue infections such as abscesses or cellulitis.
- There is a possibility for longer lasting or more severe infections with CA-MRSA if the initial antibiotic prescribed is not capable of killing the bacteria.
