People risk fungal infections when the stability of microorganisms in the vagina, mouth, intestines and other places in the body is interfered with, and results in an overgrowth of fungus. Pathogenic fungi cause human infectious diseases which are classified according to their degree of tissue involvement and means of entry to the host. (Cowan & Talaro, 2009; 403). Superficial mycoses are restricted to the outmost cover of the skin, the hair, and nails. Some common examples are ringworm, athletes foot, jock itch, and yeast infections. Cutaneous mycoses go deep into the epidermis, and also comprise invasive hair and nail infections. Subcutaneous mycoses infections are localised to the dermis, subcutaneous tissue or adjacent structures such as; muscle and fascia. However, systemic mycoses mainly involve deep infections of the internal organs because primary pathogens that are inherently virulent originate primarily in the lungs, and may spread through to many organ systems (Jucker, 2003; 18). Pathogenic fungi produce infections that are classified into two: systemic and superficial. Systemic infections involve internal organs. Fungi can transmit a disease to deeper tissue causing septicemia, which
