How Common Is MRSA?
About 0.8%-2% of the U.S. population is colonized with MRSA, and these people are called MRSA carriers. The proportion of health care-associated Staphylococcal infections that are due to MRSA (known as hospital-associated MRSA or HA-MRSA) rapidly increased from 2% in intensive-care units in 1974 to 64% in 2004. Approximately 126,000 hospitalizations are due to MRSA yearly. Recent data suggest that MRSA causes about 59% of all skin and soft-tissue infections. Invasive (serious) MRSA infections occur in approximately 94,000 people each year and are associated with approximately 19,000 deaths, reportedly more deaths than HIV per year. Of these MRSA infections that cause death, about 86% are HA-MRSA and 14% are CA-MRSA (also termed community-acquired MRSA because these MRSA infections are acquired outside health care settings). The CDC currently reports a decline in reported MRSA infections; HA-MRSA has dropped by about 28% and a 17% drop in CA-MRSA. These drops may be due to increased public awareness and utilization of methods to avoid transmitting these bacteria to other people.
