Harmful fungi can cause infection that are potentially harmful to the human body. There are many types of fungal infection and some of the common ones includes fungal nail infection, ringworm, vaginal candidiasis, candida infection of the mouth, aspergillosis, pneumocystis pneumonia (PCP) and more. Most of these fungal infections will produce a variety of symptoms such as skin changes, cracking or peeling of skin, itchiness, respiratory symptoms, discharge from the genital area, whitish spots in the oral cavity and many more.
