Tinea, or ringworm, is a fungal infection that can affect different parts of the body. It is usually treatable with over-the-counter medication, but persistent cases may require prescription antifungal medication. The infection is caused by direct contact with an infected person or animal and can be prevented by good personal hygiene. Symptoms include itching, redness, and dryness, and a doctor can diagnose and prescribe appropriate medication.
Tinea is a type of fungal infection commonly known as ringworm. There are several classifications, characterized by the specific fungus involved and the part of the body affected. A person may experience a general case of ringworm on the body or an isolated infection of the scalp, feet, nails, or groin region. Most cases cause itching, mild swelling, redness, and burning sensations. The condition is usually treatable with over-the-counter medications, although ringworm that persists for several weeks or causes significant pain may need to be treated with prescription antifungal medications.
The outbreaks are caused by fungi of the genera Trichophyton, Microsporum and Epidermophyton, which are found throughout the world. An individual usually acquires ringworm from direct contact with an infected person or animal. Athlete’s foot and jock’s itch, two common forms of tinea, can develop after coming into contact with a contaminated shower floor, towel, or piece of clothing.
Tinea symptoms can include skin redness, itching, and dryness. Infections in the arms, legs, and torso often create raised, dark red ring lesions along the outer edges. Some cases lead to the appearance of red and white pus-filled blisters and areas of dry, flaky, flaky skin. Ringworm on the scalp can cause hair loss at the site of infection.
Most mild cases, including athlete’s foot and itching, can be treated at home with over-the-counter topical solutions available in most pharmacies and supermarkets. Topical sprays, creams, and lotions can soothe itching and burning sensations and resolve tinea in less than a month. In addition to applying medicine, a person can shorten healing time by frequently washing the skin with mild soap and water. Doctors strongly suggest that people avoid scratching the affected area, as this may further irritate the skin and create the opportunity for further bacterial or fungal infections. An infection that doesn’t go away after about four weeks should be brought to the attention of a primary care physician.
A doctor can usually diagnose tinea by examining the site of the infection and asking about symptoms. He or she may decide to collect a small sample of skin for laboratory analysis of the specific fungus involved. After making an accurate diagnosis, your doctor can prescribe oral or topical antifungal medications and explain ways to avoid future infections. Most cases of ringworm can be prevented by maintaining good personal hygiene and wearing sandals in the locker room and showers.
