Tinea is a very contagious mycosis and is also known as ringworm. the fungus responsible for ringworm includes the microsporum and trichophyton species. Horses usually contract it when conditions are damp, dark or crowded( such as stable where they are confined during winter and fall).

Once again, tinea is more likely to infect horses whose immune system is not strong enough(young ,debilitated horses...). The lesions are most typically seen around the girth ,on the face and shoulders.

Symptoms
they start with circular tufts of hair falling out to reveal crusty patches of skin. Lesions will appear in the affected area when the crusty patches become infected. Ringworm spreads quickly on the body, is highly contagious and must be treated as soon as possible.

Treatment
If ringworm is treated at early stages, Derfen will eliminate the fungus. But as soon as patches are more significant, the infected horse must be isolated and a veterinarian should be called out. In the meantime, it is of upmost importance to disinfect your tack and equipment, trailer, fencing...in other words, everything. Horses that have been in contact with the infected horse must also be treated.

Caution
Ringworm is contagious to human beings. So people who have been in contact with the infected horse must be treated as well.
