[2] [3] It is sometimes practiced in patients with severe burns and leukemia, or those undergoing chemotherapy. [ 4 ] [ 5 ] When reverse isolation is practiced in laminar air flow or high-efficiency particulate air (HEPA)-filtered rooms, there was an improvement in survival for patients receiving bone marrow or stem cell grafts.
Although people receiving chemotherapy are encouraged to wash their hands, avoid sick people, and take other infection-reducing steps, about 85% of infections are due to naturally occurring microorganisms in the person's own gastrointestinal tract (including oral cavity) and skin.

Surveillance definitions exist for infections of the bloodstream, urinary tract, pneumonia, surgical sites and gastroenteritis. [citation needed]
It can permit the successful infection of a host by pathogenic microbes that manage to evade immune elimination. [8] Additionally, the induction of peripheral tolerance within the local microenvironment is a strategy employed by many cancers to avoid detection and destruction by the host's immune system.
