Fungal infections are more serious and can cause ringworm of the head, ringworm of the body, ringworm of the femur, or ringworm of the feet. If not treated in time or because of scratching or scalding, it can cause secondary bacterial infections, which can lead to fungemia, sepsis, and even life-threatening conditions. Therefore, patients suffering from fungal infections should be treated promptly. Topical antifungal ointment, such as clotrimazole ointment or terbinafine hydrochloride cream, can be used. If the condition is serious, the patient can take oral antifungal medication, such as terbinafine hydrochloride tablets or itraconazole capsules, but the specific diagnosis and treatment should be carried out under the guidance of a doctor.
