Staphylococcus aureus is a leading cause of community-acquired and healthcare-associated bacteremia. The annual incidence of S. aureus bacteremia (SAB) in the United States is 38.2 to 45.7 per 100,000 person-years [1,2]; elsewhere in the industrialized world, the incidence is approximately 10 to 30 per 100,000 person-years . Rates are higher among specific populations (such as patients on hemodialysis) (table 1). The 30-day all-cause mortality of S. aureus bacteremia is 20 percent [4-6].
The epidemiology of and risk factors for SAB in adults will be reviewed here. The management of SAB is discussed separately. (See "Clinical approach to Staphylococcus aureus bacteremia in adults".)
Bacteremia due to S. aureus can be classified into three categories :
●Healthcare associated, hospital onset (ie, nosocomial)
●Healthcare associated, community onset
