Skin infections are caused by bacteria, fungi, or viruses that affect the skin’s surface or deeper layers. Common types include bacterial infections like impetigo, fungal infections such as athlete’s foot, and viral infections like herpes simplex. These infections can cause symptoms like redness, swelling, and itching.
Causes
Skin infections are typically caused by pathogens entering the skin through cuts, abrasions, or compromised skin barriers. Bacterial infections often stem from poor hygiene or contact with infected individuals, fungal infections arise from moisture and warmth, while viral infections can spread through direct contact or contaminated surfaces.
