Fungal infections are clinically seen in large amounts and long-term use of broad-spectrum antibiotics causing dysbiosis, and can also be related to the use of hormones, immunosuppressants or anti-cancer drugs, resulting in low immune function, so fungal infection beds are very common. Fungal infections focus on prevention, and can be clinically divided into two categories: superficial fungal infections and deep fungal infections. Superficial fungal infections should pay attention to hygiene, avoid direct or indirect contact with patients, while local ointment or salve can be used. Deep fungal infections can be treated clinically with antifungal drugs such as econazole if the triggering factors are removed. In addition, fungal food poisoning should be actively prevented, and consumption of moldy and spoiled food is strictly prohibited.
