Jock itch is a fungal infectious disease that is quite common and can occur in both men and women, though it is more prevalent among men. It typically appears around the upper thigh or buttock area. The fungus attaches to the surface of the skin and reproduces quickly, causing the affected area to expand and symptoms such as redness, flaking, or itching to appear. Once these symptoms occur, standardized treatment is necessary. Commonly used antifungal creams can completely cure the condition. During treatment, it is important to avoid public baths and swimming, use separate bath towels and washcloths. For patients with athlete's foot, it is advisable to wash socks and underwear separately and to frequently disinfect them with sunlight exposure. It is also recommended to avoid keeping small animals at home.
