Fungal diseases

There are only a few types of fungus that cause disease.

Overview

There are only a few types of fungus that cause disease. Skin fungi attack the skin, nails and hair. Yeast fungi (mainly candida) live in warm and moist places and can produce a white coating. Mould fungi mainly attack internal organs such as the lungs. Preventive measures include, for example, wearing shoes at swimming pools or saunas.
