Fungal infections are due to microscopic organisms that live on the dead keratin on the surface of the skin, hair and nails.
The situation may occur because of poor hygiene, but some people seem to be more prone than others to picking up these types of infections. Removing one’s socks in public places for sporting or religious purposes will certainly encourage the spread of athlete’s foot.
This usually starts between the toes and may spread to the rest of the foot. Cracking and discomfort may alert you. Fine scaling across the foot may follow. A common presentation is intermittent, itchy blistering of the instep.
The wearing of tackies, which make the feet hot, may worsen the condition.
This is a red rash in the groin that tends to spread out onto the thigh with a distinct scaly edge. It does not affect the scrotum or penis. It may be spread by sharing towels.
This occurs most frequently in children and is identified by the presence of broken hairs and scaly skin on the scalp. It may spread to the face or, less commonly, to other areas.
- Dry well especially between the toes.
- Use an antifungal cream containing clotrimazole, miconazole or terbinafine (Lamisil) until clear.
- After clearing, go back to the daily use of a foot powder.
- It is best, but probably impossible, to avoid hot footwear.
- Change your socks daily.
- Wear slip-slops in communal showers, locker rooms etc.
- Dry well.
- Avoid chafing. A male talc will actually lubricate the area.
- Prevent other children from using the same brush, comb, towel etc.
- Seek medical help.
If any of the presumed fungal rashes persists or you suspect scalp ringworm, there is highly effective systemic treatment available. Remember that some people are particularly susceptible to re-infection, particularly of the feet.
