What are the sources of skin fungi?
Some fungi live only on human skin, hair, or nails. Others live on animals and only sometimes are found on human skin. Still others live in the soil. It is often difficult or impossible to identify the source of a particular person's skin fungus. The fungi may spread from person to person (anthropophilic), from animal to person (zoophilic), or from the soil to a person (geophilic).
Heat and moisture help fungi grow and thrive, which makes them more commonly found in skin folds such as those in the groin or between the toes. This also accounts for their reputation as being caught from showers, locker rooms, and swimming pools. This reputation is exaggerated, though, since many people with "jock itch" or "athlete's foot" have not contracted the infection from locker rooms or athletic facilities.
