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".
Isolation is most commonly used when a patient is known to have a contagious (transmissible person-to-person) viral or bacterial illness. Special equipment is used in the management of patients in the various forms of isolation. These most commonly include items of personal protective equipment (gowns, masks, and gloves) and engineering controls (positive pressure rooms, negative pressure rooms, laminar air flow equipment, and various mechanical and structural barriers). Dedicated isolation wards may be pre-built into hospitals, or isolation units may be temporarily designated in facilities in the midst of an epidemic emergency.
The atmospheric documentary centers around the life of Stuart Griffiths, an ex-Paratrooper, who has since become a renowned social photographer. He journeys through England encountering ex-soldiers, experiencing the physical and emotional scars of life after the Army.
The film premiered at the Edinburgh film festival in June 2009.
The topographic isolation of a summit is the minimum great-circle distance to a point of equal elevation. Topographic isolation represents a radius of dominance in which the peak is the highest point. Topographic isolation can be calculated for small hills and islands as well as for major mountain peaks. Topographic isolation can even be calculated for submarine summits.
The following sortable table lists the Earth's 40 most topographically isolated summits.
The nearest peak to Germany's highest mountain, the 2,962-metre-high Zugspitze, that has a 2962-metre-contour is the Zwölferkogel (2,988m) in Austria's Stubai Alps. The distance between the Zugspitze and this contour is, as the crow flies, 25.8km; the Zugspitze is thus the highest peak for a radius of 25.8km around. Its isolation is thus 25.8km.
Because there are no higher mountains than Mount Everest, it has no definitive isolation. Many sources list its isolation as the circumference of the earth over the poles or – questionably, because there is no agreed definition – as half the earth's circumference.
