Fungal rashes are often red and scaly and appear in areas of the body that tend to retain moisture, such as the area between the toes or groin, according to Merck Manual. Some people develop a secondary skin rash due to an allergic reaction to the fungus.
Ringworm and jock itch are fungal infections that grow in a circular pattern, according to WebMD. Most of these skin infections respond well to over-the-counter creams or sprays. When the infection is active, the affected individual should keep the area clean and dry, and change clothing often. Some fungal infections are contagious and spread by direct contact or sharing personal items and clothing.
