Abstract: In addition to being a hospital-acquired infection, methicillin-resistant staphylococcus aureus can also be spread throughout a community like most other bacterial and viral diseases. The sample used for this study was composed purely of college students who live in close proximity to one another. Bacteria samples from 94 students were cultured in lab and tested for antibiotic resistance. It was found that 57.4% of students had S. aureus and 14.5% (of the 62 usable results) had MRSA. These results were used to determine whether activities related to the close living conditions and several hospital related factors affect a person's chance of acquiring MRSA. It was found that these risk factors do have an impact of the prevalence of MRSA in the college community. Introduction: The scientific community acknowledges that microbes are becoming more and more antibiotic resistant. Once considered miracle drugs, antibiotics have switched from solution to problem because it is not possible to control the resistant bacteria. One of the strains of resistant bacteria of concern is Methicillin-resistant Staphylococcus aureus, which is particularly problematic in hospitals where is has been more prevalent historically. However, people who contract MRSA are not contained in a hospital. They are allowed to spread the resistant bacteria to their neighbors, and that could lead to an epidemic that scientists are trying to prevent. In Europe, there is a program called the European Antimicrobial Resistance Surveillance System which tests hospital patients for MRSA all across Europe. They found that MRSA was much more prevalent in Southern European countries compared to Northern European countries. In the Netherlands, for example, only 0.6% of the 5,359 people tested had MRSA compared to 40.9% of 1,470 people in Italy (Tiemersma, 2004). However, the Netherlands have taken several more steps in the fight against MRSA than most. They have a national search and destroy policy and place strict policies on antibiotic use (Wertheim, 2004). In countries with no such policies, incidences of MRSA are higher. Recently, in areas where people live in close contact with one another, community-acquired MRSA has surfaced as a major problem. Skin-to-skin contact is one direct route, but the bacteria can also be transmitted by sharing communal spaces, like locker rooms. In general, the risk factors include contact, crowding, contaminated surfaces, and lack of cleanliness (Weiner, 2008). One such place is in
