Ringworm

Ringworm, medically known as tinea, is a common fungal infection of the skin not caused by a worm. It's named for its characteristic appearance: a red, itchy, circular rash with clearer skin in the middle. There are several types, each named for the part of the body it affects, such as tinea pedis (athlete's foot), tinea cruris (jock itch), and tinea capitis (scalp). The infection occurs when dermatophytes, a group of fungi that thrive on keratin, the protein in skin, hair, and nails, multiply excessively. These fungi are often spread through direct contact with infected individuals, animals, or objects like clothing and bedding.

Treatment for ringworm typically involves antifungal medications, which could be topical or oral, depending on the severity and location of the infection. Over-the-counter creams and powders are often effective for mild cases, while more severe or extensive cases might require prescription-strength medications. Good hygiene practices and keeping the skin clean and dry can help prevent the spread and recurrence of the infection. Additionally, it is important to avoid sharing personal items and to treat infected pets to minimize the risk of transmission.
