Skin Infections

Skin infections occur when a pathogen, such as bacteria, virus, or fungus, enters the body through a cut or break in the skin and causes an infection. These infections can range from mild to severe and can affect anyone, regardless of age or health status.

Types of Skin Infections

• Bacterial Skin Infections: Caused by bacteria such as Staphylococcus aureus, Streptococcus pyogenes, and Pseudomonas aeruginosa. Examples include impetigo, folliculitis, and cellulitis.
• Viral Skin Infections: Caused by viruses such as herpes simplex, varicella-zoster, and human papillomavirus (HPV). Examples include cold sores, chickenpox, and warts.
• Fungal Skin Infections: Caused by fungi such as Candida, Aspergillus, and Trichophyton. Examples include athlete's foot, ringworm, and yeast infections.

• Redness and swelling of the affected area
• Pain or tenderness to the touch
• Warmth or heat emanating from the affected area
