Your skin helps protect you from germs, but sometimes it can get infected by them. Some common types of skin infections are

• Bacterial: Cellulitis and impetigo. Staphylococcal infections can also affect the skin.
• Viral: Shingles, warts, and herpes simplex
• Fungal: Athlete's foot and yeast infections
• Parasitic: Body lice, head lice, and scabies

Treatment of skin infections depends on the cause.
