If localized skin symptoms such as erythema, pimples, blisters, flaking, with itching, can be considered to be caused by fungal infection. Fungal infections are mainly caused by human contact with fungi. Due to the different parts of the body invaded by fungal infections, the clinical manifestations are also different. Fungal infections of the skin are usually manifested as erythema, papules, blisters, and flaking symptoms, usually accompanied by a certain degree of itching. As the area of the infection increases, the lesions will expand around it and may appear as ring-shaped or circular damage, with new lesions appearing in the center. If a fungal skin infection is suspected, it is recommended to visit a regular hospital and be treated under medical supervision.
