Fungal Infections

Fungal infection can be defined as an infectious disease caused by fungi. A fungal infection is also referred to as mycosis. Fungal infections are contagious, spreading from person to person. Mycosis can be contracted even from an infected animal or contaminated soil. The most common symptom is skin rashes and vaginal discharge in females.
