Incidence and Prevalence of MRSA

Methicillin-resistant Staphylococcus aureus infection is a serious worldwide health concern. About 85 percent of serious, invasive MRSA infections are health care-associated infections. Incidence of community-associated MRSA varies according to population and geographic location. In the United States, more than 94,000 people develop serious MRSA infection and about 19,000 die from infection each year.

According to the Centers for Disease Control and Prevention (CDC), Staphylococcus aureus (including MRSA) caused about 11 percent of health care-associated infections in 2011. Each year in the United States, about 1 out of every 25 hospitalized patients contracts at least one infection in the hospital. More than 290,000 hospitalized patients are infected with Staphylococcus aureus and of these staph infections, approximately 126,000 are related to MRSA.
