Mycoses are infections caused by fungi. Some fungi have adapted to a parasitic lifestyle in the skin, hair and nails of humans. They can not live without destroying the stratum corneum of the skin and its appendages, and thus pass from one person to another.
Fungal infections of the skin (dermatomycoses) and nails (onychomycosis, synonyms - nail fungus) are very common. They represent about 10% of the disease burden of the population according to some sources and ,according to others , 2-3 times more. The frequency of such infections over the past 10 years has increased more than two times. The increased incidence of fungal infection is due to the fact that many people infected with nail fungus avoid treatment or fail to seek medical advice.
