How many levels of infection control are recognized?

The correct answer reflects the fact that there are three recognized levels of infection control in healthcare settings. These levels are established to ensure a comprehensive approach to preventing the transmission of infections.

The first level is standard precautions, which include basic hygiene practices such as handwashing and the use of personal protective equipment (PPE) to minimize exposure to pathogens. This level applies to all patients, regardless of their infection status.

The second level comprises transmission-based precautions, which are more targeted and depend on how infections spread. This level is further divided into airborne, droplet, and contact precautions, each addressing specific modes of pathogen transmission.

The third level involves additional control measures such as sterilization and disinfection protocols, particularly in surgical or critical care environments, where the risk of infection is higher and where more stringent measures are needed to protect patients.

Understanding these three levels is crucial for healthcare professionals to implement effective infection control strategies, thereby safeguarding both patients and staff from healthcare-associated infections.
