Disease description:

My boyfriend went to a bathhouse and simply took a shower—nothing else happened. Afterward, he suddenly developed athlete's foot. The doctor diagnosed it as tinea pedis (a type of hand and foot fungus). What causes hand and foot fungal infections?

Tinea manuum and tinea pedis are generally caused by fungal infections, primarily affecting the hands and feet. Main contributing factors include hygiene conditions, environmental factors, and the body's immune function. For example, if you are exposed to clothing or towels used by an infected person, your body's resistance may decrease, or if your personal hygiene is poor. Prolonged exposure to damp environments can lead to fungal skin infections. After infection, symptoms such as skin blisters, erosion, scaling, papules, and itching may appear. Diagnosis of tinea manuum and tinea pedis requires treatment with antifungal medications.
