It is normal for a variety of bacteria and fungi to live on your body; in fact, many of these are quite useful and contribute to good health. However, some bacteria and fungi can multiply rapidly, leading to infection. Tinea results from a particular type of fungus multiplying too rapidly on the skin, scalp or nails. The fungi that can infect the skin in this way are known as dermatophytes. Prolonged moistness on the body, such as sweat, creates an ideal environment for this overpopulation. You can also catch tinea by contact with contaminated objects and surfaces, such as combs, articles of clothing, locker room floors, or showers. It can even be transmitted through a pet. Poor circulation and immune deficiency also increase the risk for Tinia Infections.
