Athletes Foot:

Athlete's foot (tinea pedis) is, like Ringworm (see Ringworm), a fungal infection of the skin. It is surprisingly common. At any one time about 10% of people in the UK are thought to have this condition. Some types of fungi like to live in human skin and are often present without the person being aware of this. However, under certain conditions the fungi are able to multiply and cause an obvious infection. Fungi favour warm, moist and airless conditions so the skin between people's toes is an ideal site for them. Athlete's foot is infectious and can be passed on from person to person, eg, in communal showers at the swimming baths or sports centre (hence its name!).

Athlete's foot typically starts between the toes as an itchy and scaly rash. This may progress to cracking of the skin with associated soreness and spread gradually along the toes on to the skin of the foot if not treated. If treated early, athlete's foot is no more than a nuisance. However, if people do not recognise the infection and scratch the itchy area, the infection can be spread to other parts of the body. Very occasionally, cracked skin can allow bacteria to enter the foot and cause more serious infections.

Treatment for athlete's foot is very straightforward and an anti-fungal cream can be bought over-the-counter at the pharmacy or prescribed by a doctor. As with the treatment of fungal infection on the body (see Ringworm: tinea corporis), it is important to apply the cream not only to the obviously affected area, but to the surrounding 6 cm of normal skin in addition. The rash usually settles within 3 weeks and once again it is important to continue with the treatment for a further 10 days after there is no obvious infection left to see.

In the minority of cases where the infection has become very well established and possibly infected with other germs in addition, different treatments may be necessary.

Knowing the conditions that the fungus likes best leads to simple steps which can be taken to prevent athlete's foot recurring:

Wash feet and toes daily taking great care to dry the skin between the toes thoroughly afterwards
Avoid sharing towels in communal changing rooms
Change socks daily
Opt for cotton rather than nylon socks to reduce sweating
Wear leather rather than plastic footwear for the same reason
