Infection control measures practiced by healthcare personnel in healthcare facilities to decrease transmission and acquisition of infectious agents (e.g., proper hand hygiene, scrupulous work practices, use of personal protective equipment (PPE) [masks or respirators, gloves, gowns, and eye protection]; infection control measures are based on how an infectious agent is transmitted. The UK guidelines have been laid out by the National Institution for Clinical Excellence (NICE) in a document which was updated in 2003 and which is currently being updated again.
