Fungal Infections: Causes, Symptoms, Treatment & Prevention
Fungal infections are among the most common skin problems seen in dermatology clinics, especially in warm and humid climates like India. These infections can affect the skin, nails, scalp, and groin area, leading to itching, rashes, and discomfort.
