What is tinea?
TInea, commonly referred to as ringworm, is a fungal infection of the skin of the body (called tinea corporis), frequently affecting the scalp (tinea capitis), groin (tinea cruris, or jock itch), feet (tinea pedis, or athlete’s foot), or nails (tinea unguium, or onychomycosis). While tinea is seen most frequently in children, it occurs in all age groups.
Skin Problems Spotlight
Although ringworm is the term most frequently encountered, the infecting agent is a fungus that thrives in warm, moist areas and is most likely to occur with frequent wetness from perspiration or as a complication of minor injuries to your nails, scalp or skin. The name ringworm comes from a ring-like pattern frequently seen with tinea, the development of red patches on the skin that are often redder around the outside (forming the ring), with a more normal skin color in the center.
Tinea is contagious through skin-to-skin contact or through contact with contaminated items. It is highly treatable, usually clearing up within four weeks of starting treatment, and is not life threatening.
While tinea is a condition requiring prompt attention, it is not an emergency. At the same time, left untreated, it can become complicated by a more widespread bacterial infection. Seek prompt medical care if you are being treated for tinea but symptoms recur or persist after four weeks of care, if it spreads to your scalp or beard, or if you see signs of a bacterial infection developing, marked by symptoms such as swelling in the affected area, skin that is warm to the touch, an increase in redness, pus or discharge, fever, or streaks of red along the skin, particularly on a limb.
What are the symptoms of tinea?
Symptoms of tinea include raised, red, scaly patches with sharply defined edges that itch and blister, usually with oozing of fluid. Sometimes the skin near a tinea infection becomes lighter or darker, and if the scalp or beard is infected, you will usually see bald patches. Infected nails became thick, discolored, and sometimes crumbly.... Read more about tinea symptoms
What causes tinea?
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....

How is tinea treated?
Tinea responds well to treatment with over-the-counter antifungal products. These treatments come in powder, lotion or cream form. However, for resistant or persistent infections, prescription medications may be needed. If the scalp is infected, an oral medication will be needed. Finally, if the infection becomes aggravated and develops into a bacterial infection, antibiotics may also be needed.... Read more about tinea treatments
