Fungal infections can occur almost anywhere on the body, including on the feet or between the toes, around the groin or on the torso, hands, face or scalp. They are caused by many different types of fungi, which may spread from one part of the body to another and may originate from contact with infected people, animals or areas, such as wet floors in public showers. 

People who perspire freely or often have their hands in water are more often affected, as fungi grow in moist, warm conditions. Inflamed or otherwise damaged skin, hormonal imbalances, antibiotics and diseases such as diabetes can also increase the chance of infection.
Affected areas will generally be inflamed and itchy and may also contain lesions or scaly patches. Secondary bacterial infection may occur and the skin may also be affected by seborrhoeic dermatitis, psoriasis and eczema.

Careful drying of the skin and early treatment of the condition to prevent its spread to other areas is essential. Avoid soap, which may further irritate the skin, and use a soap-free cleanser instead.
Wearing airy, absorbent clothing, light open shoes or sandals and avoiding rubber-soled shoes, and synthetic underwear and socks will also help.

To ensure that the fungal infection is completely treated and to help prevent recurrence, it is important to continue treatment for at least 2 weeks after the initial symptoms have disappeared.
Seek medical advice for severe conditions that do not respond to treatment.
