Understanding the risk factors that facilitate the transmission of infectious agents is important for preventing the spread of these microorganisms in various healthcare settings. In addition, the recognition of risk factors supports determining the need for additional interventions when patients colonized or infected with these microorganisms enter healthcare facilities. This understanding is also key for healthcare-associated infection surveillance data that adjust for certain infection risks and are used for interfacility comparison of infection rates. This knowledge then aids in the development and implementation of interventions to mitigate the transmission of infectious agents.Ref 21-1 National Nosocomial Infections Surveillance System.
