Isolation (health care)
![The Aeromedical Biological Containment System (ABCS) is an air-transportable high isolation module for movement of highly contagious patients.[10]](/uploads/202502/07/Aeromedical_Biological_Containment_System_(ABCS)4408.jpg)
In health care facilities, isolation represents one of several measures that can be taken to implement infection control: the prevention of contagious diseases from being spread from a patient to other patients, health care workers, and visitors, or from outsiders to a particular patient (reverse isolation). Various forms of isolation exist, in some of which contact procedures are modified, and others in which the patient is kept away from all others. In a system devised, and periodically revised, by the U.S. Centers for Disease Control and Prevention (CDC), various levels of patient isolation comprise application of one or more formally described "precaution".
