Often called a “superbug” due to its strong antibiotic resistance, Methicillin-resistant staphylococcus aureus (MRSA) is the most pathogenic of all staphylococci. It has been found to be responsible for a large number of infections that are difficult to treat and is a growing concern in the health care system. At any given time, approximately 20% to 30% of individuals in the community are colonized with staphylococcus aureus (S. aureus) and are persistent carriers, up to 50% are intermittent carriers and up to 80% have been colonized at some time (MDGuidelines, n.d.). About 59% develops local infection and more serious systemic infections develop in about 94,000 individuals annually (Naber, 2009). MRSA also accounts for 60% of S. aureus isolated form Intensive Care Units, and 50% of all nosocomial S. aureus infections (Yang et al., 2010).
MRSA is a strain of the Staphylococcus Aureus, a type of staph bacteria that is resistant to several antibiotics. The bacteria can be present without causing any infection and in this case is called colonization, and when it is present and causes symptoms it is called an infection. The CDC states that MRSA may cause skin and other infections in the community, as well as more severe problems such as bloodstream infections, pneumonia, surgical site infections and other chronic and disabling conditions (CDC, 2013). MRSA is difficult to treat and is a growing concern for both patients and healthcare workers alike. Between the years of 1999 and 2005, there was an increase of 119% in documented cases of MRSA. In the United States, it has now being termed an endemic, and is classified as a national health priority by the Center for Disease Control (Yang et. al., 2010).
