Detailed answer

A rash is a broader term describing any abnormal changes in the skin appearance or texture. It can be caused by a wide range of factors, including allergies, irritants, infections, or autoimmune conditions. On the other hand, a fungal infection is a specific type of skin infection caused by fungi. Fungal infections commonly occur in warm and moist areas of the body, such as the feet or groin. They can present as red, itchy, scaly patches that may have a distinct border. A proper diagnosis is crucial to differentiate between a rash and a fungal infection, as the treatment approaches differ.
