Isolation (health care)

In health care, isolation refers to various measures taken to prevent contagious diseases from being spread from a patient to other patients, health care workers, and visitors, or from others to a particular patient. Various forms of isolation exist, some of which contact procedures are modified, and others in which the patient is kept away from all others.

Isolation is most commonly used when a patient has a viral illness. Special equipment is used in the treatment of patients on the various forms of isolation. These most commonly include gowns, masks, and gloves.

Those who are kept in strict isolation are often kept in a special room at the facility designed for that purpose. Such rooms are equipped with a special lavatory and caregiving equipment, and a sink and waste disposal are provided for workers upon leaving the area.

Contact isolation
