Skin infections are caused by bacteria, viruses, fungi, or parasites that invade the skin and cause inflammation. The symptoms of a skin infection can vary depending on the type and severity of the infection, but commonly include redness, swelling, warmth, and pain or tenderness in the affected area. Some infections can also cause blistering, crusting, or itching. Treatment for a skin infection typically involves the use of topical or oral antibiotics, antiviral or antifungal medication, or other prescription medications depending on the cause and severity of the infection. Preventive measures, such as good hygiene and avoiding contact with infected individuals or objects, can also help reduce the risk of developing a skin infection
