Antibiotic-Resistant Staph Infections reduce in U.S.


Methicillin-resistant Staphylococcus aureus (MRSA) infections occur most frequently among persons in hospitals and healthcare facilities, including nursing homes, and dialysis centers.

The number of "invasive" MRSA cases severe infections that typically require hospitalization, and can be fatal has declined significantly in the United States. In 2011, there were more than 30,000 fewer invasive cases than in 2005, the study shows. That's a 31 percent reduction in the rate of infection (per 100,000 people).

The drop was seen primarily in MRSA infections acquired at hospitals and nursing homes, where most cases are picked up, said Dr. Raymund Dantes, a physician and researcher at Emory University in Atlanta. These cases are called health-care-associated MRSA, and often involve pneumonia and infections of the bloodstream and surgical sites, according to the Centers for Disease Control and Prevention (CDC).

The number of community-associated MRSA cases has declined by 5 percent since 2005, according to a published in the journal JAMA Internal Medicine ("National Burden of Invasive Methicillin-ResistantStaphylococcus aureus Infections, United States, 2011"). The number of deaths associated with MRSA has also dropped. In 2005, more than 21,000 people in the U.S. were infected with MRSA at the time of their death, Dantes said. By 2011, the number had fallen to slightly more than 11,000 a 47 percent drop.
