Also called Dermatophytosis, ringworm is an infection on the surface of the skin. It's characterized by an itchy, red circular rash with healthy-looking skin in the middle. The name “ringworm” is derived from the early belief was that the infection was due to a worm, which it is not. Ringworm is caused by fungus. Nevertheless, the name ringworm has stuck to this day. The fungi that cause this condition feed on keratin, the material found in the outer layer of skin, hair, and nails. In fact, skin fungi can only live on the dead layer of keratin protein on top of the skin. They rarely invade deeper into the body and cannot live on mucous membranes.
There are various ways of getting ringworm. One can get it from other human beings (it can spread by skin-to-skin contact with an infected person), from animals (by petting an animal), from soil (but this occurs very rarely, and it has to be a prolonged contact with very infected soil), and from objects (if an infected person has recently touched an object, and then a healthy person has touched it, they will most likely get ringworm).
Risk Factors and Prevention

For instance, if one lives in crowded, damp, or humid conditions; is in close contact with an infected person, sweats excessively, wears tight clothes, participates in contact sports, shares clothing with a person that has a fungal infection, has a weakened immune system, etc, then they are in great risk of being infected. This is why, the best way of avoiding ringworm is having good personal hygiene, not sharing clothes, avoiding infected animals, etc.
