Fungal Infections: Causes, Symptoms, Prevention & Treatment by a Dermatologist

🔹 What are Fungal Infections?

Fungal infections are skin problems caused by the overgrowth of fungi (microscopic organisms). These fungi thrive in warm, moist areas of the body such as the feet, groin, armpits, nails, and skin folds. They are common, contagious, and can affect anyone, but usually are not life-threatening if treated on time.
