Final answer:
Human fungal infections are categorized into superficial, subcutaneous, and systemic mycoses. Superficial mycoses affect the outer layers of the skin, hair, and nails. Systemic mycoses, such as histoplasmosis and coccidioidomycosis, can spread throughout the body and are more severe.
Step-by-step explanation:
The three types of human fungal infection (mycoses) are superficial mycoses, subcutaneous mycoses, and systemic mycoses. Superficial mycoses affect the skin, hair, and nails and include conditions such as tinea pedis (athlete's foot) and tinea corporis (ringworm). Subcutaneous mycoses invade deeper tissues beneath the skin and can be caused by a puncture wound that allows fungi to enter. Systemic mycoses are the most serious as they spread throughout the body after entering typically through the respiratory system; examples include histoplasmosis, coccidioidomycosis (valley fever), and blastomycosis. Fungal parasites such as Candida can cause infections like candidiasis, while several ascomycetes cause diseases including aspergillosis and Valley fever.
