Skin infections occur when harmful microorganisms, such as bacteria, viruses, or fungi, invade the skin. These infections can lead to symptoms like redness, swelling, pain, and sometimes pus formation. Common types include bacterial infections like impetigo, viral infections such as herpes, and fungal infections like athlete's foot. Treatment for skin infections often involves topical or oral medications, depending on the severity and type of infection. Maintaining good hygiene and keeping the skin clean can help prevent these infections. In some cases, a healthcare professional may need to drain abscesses or prescribe stronger medications to effectively treat the infection.
