Today, more people die from healthcare associated infections here in the United States than all the deaths from auto accidents and gun violence combined, over 99,000 annual or roughly 275 people a day, a published range of estimates for the annual direct hospital cost of treating healthcare-associated infections (HAIs) in the United States. Applying two different Consumer Price Index (CPI) adjustments to account for the rate of inflation in hospital resource prices, the overall annual direct medical costs of HAI to U.S. hospitals ranges from $28.4 to $33.8 billion (after adjusting to 2007 dollars using the CPI for all urban consumers) and $35.7 billion to $45 billion (after adjusting to 2007 dollars using the CPI for inpatient hospital services). After adjusting for the range of effectiveness of possible infection control interventions, the benefits of prevention range from a low of $5.7 to $6.8 billion (20 percent of infections preventable, CPI for all urban consumers) to a high of $25.0 to $31.5 billion (70 percent of infections preventable, CPI for inpatient hospital services).
In 2014, results of a project known as the HAI Prevalence Survey were published. The Survey described the burden of HAIs in U.S. hospitals, and reported that, in 2011, there were an estimated 722,000 HAIs in U.S. acute care hospitals (see chart below). Additionally, about 75,000 patients with HAIs died during their hospitalizations. More than half of all HAIs occurred outside of the intensive care unit.

|Primary Bloodstream Infections||71,900|
|Surgical site infections from any inpatient surgery||157,500|
|Other types of infections||118,500|
|Estimated total number of infections in hospitals||721,800|
