Mycosis is an infection caused by a microscopic fungus (Candida, Mycrosporum…).
Development and sites of mycoses
These frequently occur between the toes (athlete's foot) following infection in swimming pools or from the ground. Wearing shoes produces a warm, moist environment that then predisposes to microbial growth. The infection can also affect the internal surface of the nail (nail mycosis).
The mycoses can also occur in the external tracts (vagina, mouth, intestines, lungs), particularly in immunsuppressed people.
