Skin infections refer to any type of inflammation or irritation that occurs on the skin's surface. These conditions can be caused by a variety of factors, including bacteria, fungi, viruses, and parasites. Some common types of skin infections include acne, impetigo, ringworm, scabies, and athlete’s foot. Skin infections can range from mild to severe, with symptoms such as redness, swelling, itching, rashes, or blisters. Treatment for skin infections may include over-the-counter medications, prescription drugs, or in some cases, medical attention from a healthcare professional.
