Safety and efficacy UV Sanitization during novel Coronavirus pandemic
DNA damage has been reliably shown to have correlation and causation of Squamous cell carcinoma and other cancers of the skin. Recently, the use of sterilizing methods have increased dramatically due to the novel Coronavirus pandemic, and while many rapidly adopted sanitization measures have no known carcinogenic effects (namely alcohol-based hand sanitizers, and the use of face masks), other methods such as UV sterilization pose a health risk if incorrectly applied directly to the skin. Such misuse presents carcinogenic risks, which must be offset against the possible improved health outcomes in santization that result from the correct use of such methods.
Although UV sterilization is considered a risk factor in development of skin cancer, the increased risk is not well understood. In particular, the risk is dependent on the wavelength of UV radiation that is used in sterilization. UV-C has been shown to be carcinogenic, while UV-B has not. UV-B is what we are exposed to in the sun, while UV-C is what is used in sanitizers. It is possible that UV-C has been shown to be carcinogenic only because of the increased exposure to UV-C in sanitizers. UV-C is easier to block with glass and some clothing materials. The UV-C sterilization methods used on reusable medical equipment are not able to be easily blocked by regular clothing. However, several methods have been suggested to help protect the skin from UV-C by the CDC. The CDC recommends using UV-C safe clothing such as UV-C protective lab coats. Also, UV-C protective goggles should be used when handling UV-C sterilized equipment.
BACKGROUND AND AIM:
For regular residential business and commercial use, many UV sanitizers are designed for safety, with enclosed sanitizing compartments for smartphones and other small items, and there are many products available on the market, with safe products being sold for UV sanitizing for home use. Tanning booths and other potential sources of UV light are well-studied and will not be examined as part of primary research. Ultraviolet (UV) radiation is a commonly occuring form of light in nature (as in sunlight), in industry (as in welding, dentistry, and other fields), and academia. While sunbathing is a common passtime, strong UV light is a recognized carcinogen. The aim of this study was to assess the association between UV exposure and the risk of non-melanoma skin cancer (NMSC).
