Fungal Infections is most commonly caused by a type of fungus called a dermophyte that infects the top layer of the skin, hair or nails. Dermatophyte infection of the skin is known as ringworm (tinea).

Fungal Infections such as ringworm are caused by types of fungi that like warm, moist areas of the skin, such as between the toes or fingers, in the groin, and on other parts of the body where there are folds of skin. Ringworm is not caused by a worm. The fungus can be carried by kittens and puppies, combs, brushes, pillows, hats, and towels, and is found in areas that are warm and moist, such as locker rooms and showers.
Yeasts such as candida are commonly found on the skin and in the vagina where they are usually saprophytes (live peaceably without causing harm to the host) – in such cases, there is no need to treat the yeast. Sometimes, they can multiply and change to a form that causes itching and rashes – in such situations, treatment is warranted.
Depending on the site and severity, fungal infections may be treated with anti-fungal creams or tablets. It is important to keep the affected area clean and dry, and to avoid scratching.
