A skin infection caused by the colonization of a variation of Trichophyton and other specific fungi is called ringworm. Ringworm infections are contagious and can be spread from one individual to another through direct contact and sharing the same objects. Ringworm can also be spread from animals to humans. Ringworm can develop at any age, but it occurs most often in children. Ringworm is also more likely to occur in individuals who live in warm and moist climates. This condition has a reputation for being contracted from swimming pools, locker rooms, and showers.
Individuals can prevent ringworm by washing their hands, wearing sandals in the locker room, and thoroughly drying between their toes. Treating ringworm means cutting fingernails short and keeping them clean. Individuals will need to shower after exercise and change their socks and underwear daily. However, ringworm treatment often also requires antifungal creams, antifungal shampoo, and even oral medications.
An individual who contracts ringworm can develop a ring-shaped rash. This rash is known to manifest anywhere from between four and fourteen days after the individual's skin makes its first contact with the ringworm-causing fungi. The characteristic ring-shaped rash is what gives this fungal infection its name. The notorious ring-shaped rash appears as red or pink on the skin of individuals who are fair-toned. It appears as gray or brown on those with darker skin.
This ring-shaped rash tends to become more expansive or spreads out over time, but it is known to grow slowly. The ring-shaped rash is usually flat in the center, with the ring's border being raised and scaly. When the patient is recovering from ringworm, the center of the ring-shaped rash spots will be the first to be clear of red color and abnormal textures.
