About Infection Prevention and Asepsis
Asepsis covers the chain of infection, hand hygiene, personal protective equipment, standard and transmission-based precautions, sterilisation, disinfection and safe waste disposal. The key distinction is between medical asepsis, which reduces microorganisms, and surgical asepsis, which maintains a sterile field during invasive procedures.
