Disorders of the Skin - Fungus infections
Fungi are plantlike parasitic growths found in the air, in water, and in the soil. They comprise a large family that includes mushrooms, and are responsible for mildew and mold. Only a small number cause disease.
This condition is caused not by a worm but by a group of fungi that live on the body's dead skin cells in those areas that are warm and damp because of accumulated perspiration. One form of ringworm attacks the scalp, arms, and legs, especially of children, and is often spread by similarly affected pets. It appears as reddish patches that scale and blister and frequently feel sore and itchy. Ringworm is highly contagious and can be passed from person to person by contaminated objects such as combs and towels. It should therefore be treated promptly by a physician. Ringworm can best be prevented by strict attention to personal cleanliness.
Another form of ringworm, athlete's foot , usually attacks the skin between the toes and under the toenails. If not treated promptly, it can cause an itching rash on other parts of the body. Athlete's foot causes the skin to itch, blister, and crack, and as a result, leaves it vulnerable to more serious infection from other organisms. The disorder can be treated at home by gently removing the damaged skin, and, after soaking the feet, thoroughly drying and dusting between the toes with a medicated foot powder. Some of the powder should be sprinkled into shoes. If the condition continues, a fungicidal ointment can be applied in the morning and at night. Persistent cases require the attention of a physician.
