USING UV TO ENHANCE HYGIENE
An example of how UV technology is being put to good use in disinfection and purification systems can be found in hospitals when cleaning patient rooms.
Manual cleaning of rooms is still carried out by hospital staff, but time constraints may mean that thorough cleaning of all surfaces (with enough contact time of disinfectant chemicals) is not possible. In addition, some HAIs (hospital-acquired infections) such as MRSA and C. Difficile have been seen to develop resistance to cleaning chemicals, or are carried in spores that can be missed by liquid disinfectants.
Using ultraviolet light based disinfection treatments to enhance manual cleaning methods provides an added layer of defence.
Researchers at the Duke University School of Medicine in the US found that using portable UV disinfection systems in addition to standard cleaning strategies significantly decreased transmission of selected bacteria in patients who stayed overnight in a room where an infected patient was previously treated.
