Candidal Skin Infection

What is candida?

Candida is a yeast (a type of fungus). Small numbers of candida normally live on the skin and do no harm. Sometimes, under certain conditions, they can multiply and cause infection. The common sites for candida to cause infection are the vagina ('thrush'), the mouth, and the skin. This leaflet just deals with candidal skin infections. Another leaflet is available on thrush.

Why does candida sometimes multiply and cause infection?

The chance of a candidal skin infection developing is more likely in the following situations.

• Areas of skin that are moist are ideal for candida to thrive. Therefore, the common sites affected are in the folds of skin in the groin, armpits, and under large breasts. Nappy rash is sometimes due to candida. Obese people may develop candida infection between folds of skin. Sweating a lot may increase the chance of a candidal infection.
• If you have diabetes.
• If you take a long course of antibiotics or steroid medication.
• If you have a poor immune system. For example, if you have AIDS or certain types of serious blood disorder.

Is a candidal skin infection serious?

Usually not. Most infections occur in people who are otherwise healthy (although they are more common if you are overweight). Treatment usually works well. In some people, the candidal skin infection may be the first indication of another condition such as diabetes.

What is the treatment for candida skin infection?

• An antifungal cream usually clears the infection within a week or so.
• Sometimes a mild steroid cream is added to reduce inflammation and redness of the skin whilst the antifungal cream is working. (However, a steroid cream alone will make the condition worse.)
• Occasionally, if the rash is extensive, an antifungal medicine by mouth is prescribed.

Can candida skin infections be prevented?

Keep areas likely to be affected as clean and dry as possible. Always dry well after washing, particularly in the groin, armpits, and under large breasts. Some people use a hair dryer to dry these areas after washing to ensure they are dry before putting clothes on. If the infection keeps recurring for no apparent reason, a test to check for sugar (diabetes) may be advised by a doctor. Losing weight may help if obesity is contributing to this problem. If you wear dentures, always remove the dentures and sterilise them overnight (as candida infection next to the mouth is sometimes caused by dentures contaminated with candida).
