The Standard Precautions concept in healthcare dictates that healthcare workers assess risk in advance of a patient interaction and use appropriate interventions such as barriers, hand hygiene, and/or surface disinfection, to address the risk and prevent becoming contaminated by the patient or the patient’s environment. This approach has generally been credited with helping hospital employees protect themselves from acquiring infectious agents on a daily basis. However, a growing body of research has called into question whether this approach is in fact adequate.
