Detailed answer

A rash is a broad term that encompasses any abnormal changes in the skin's appearance or texture. It can be characterized by redness, itching, bumps, blisters, or dryness. Rashes can be caused by various factors such as allergies, irritation, or underlying medical conditions. On the other hand, a skin infection specifically refers to the colonization and multiplication of harmful microorganisms on the skin. This can include bacteria, viruses, fungi, or parasites. Skin infections often present with additional symptoms such as pain, swelling, warmth, pus, or fever. Treatment for rashes generally focuses on addressing the underlying cause and providing symptomatic relief, while skin infections usually require medical intervention such as the use of antibiotics, antifungal medications, or antiviral drugs.
