Health care-associated infections (HAIs) affect patients and health systems every day, causing immense suffering, driving higher health-care costs and hampering efforts to achieve high-quality care for all. HAIs are often difficult to treat, are the major driver of antimicrobial resistance (AMR) and cause premature deaths and disability. The COVID-19 pandemic, as well as outbreaks of Ebola, Marburg and mpox are the most dramatic demonstrations of how pathogens can spread rapidly and be amplified in health care settings. But HAIs are a daily threat in every hospital and clinic, not only during epidemics and pandemics. Lack of water, sanitation and hygiene (WASH) in health care settings not only affects the application of infection prevention and control (IPC) best practices but also equity and dignity among both those providing and receiving care. However, there is strong evidence that a large proportion of these infections could be prevented with IPC measures and basic WASH services, with a high return on investment. This second global report on IPC provides updated evidence on the harm caused to patients and health workers by HAIs and AMR, and presents an updated global analysis of the implementation of IPC programmes at the national and health care facility levels across all WHO regions.
