Some fungal infections can be passed on to others, usually superficial fungi through direct or indirect contact, etc. Fungal infections are diseases caused by pathogenic fungi that attack the body and are usually categorized into superficial and deep fungal infections. Superficial fungal infections are dominated by ringworm, which invades the skin, fingernails, toenails, and hair. Superficial fungal infections are contagious and can be transmitted to others through direct contact with the lesions or indirect contact with personal items such as towels, shoes and socks used by the patient. Deep fungal infections are mainly caused by Candida albicans and Cryptococcus neoformans, which invade the internal organs and deep tissues, etc. They are usually caused by the patient’s own low immunity or underlying diseases, and are usually not easy to be transmitted to others.
