Abstract: The method of prevention and treatment of microbial infections that occur on, or just below, the skin and nails of a person consisting of applying a means to inactivate the microbes thus rendering them harmless. The treatment consists of applying a means which alters the skin or nail so that the skin or nail will either no longer serve as a food source, will be inhibitory to the organism, will be toxic to the organism, or will be altered in a manner that makes it more responsive to treatment of infections.

Abstract: A method of prevention and treatment of microbial infections that occur on, or just below, the skin and nails of a person consisting of electromagnetic radiation to inactivate the microbes thus rendering them harmless. The treatment consists of irradiating an area of the skin and nails for a period of time long enough to inactivate the organisms. Some additional features which are not integral to the treatment but increase the safety of the treatment include shielding of non-infected areas from irradiation and a cover to prevent damage to sight which may result from viewing the electromagnetic radiation.
