Hospital-acquired infections (infections that patients develop while staying in the hospital following surgery or other procedures) are a very serious national healthcare crisis. One of the most serious types of hospital-acquired infections is methicillin-resistant staphylococcus aureus (MRSA). This is a type of bacteria that is resistant to certain antibiotics, including methicillin and other more common antibiotics such as oxacillin, penicillin, and amoxicillin. According to the Centers for Disease Control (CDC), data published in a study in the Journal of the American Medical Association estimated the number of people who developed the serious MRSA infection in 2005 alone was approximately 94,000 people. Approximately 18,650 patients died during a hospital stay due to a serious MRSA infection. According to the CDC, staph infections, including MRSA, occur most frequently among patients in hospitals and healthcare facilities, such as nursing homes and dialysis centers.
