1. Bacterial Infections:
The most common bacterial infections include impetigo, folliculitis, and cellulitis. These are typically caused by Staphylococcus or Streptococcus bacteria. They often result in red, inflamed skin and may require antibiotics for treatment.

2. Viral Infections:
Viral infections like herpes simplex (cold sores), varicella-zoster (chickenpox), and human papillomavirus (warts) can affect the skin. Antiviral medications are often prescribed to manage symptoms and prevent outbreaks.

3. Fungal Infections:
Fungal infections such as athlete’s foot, ringworm, and candidiasis can cause itchy, scaly patches on the skin. Antifungal creams, powders, or oral medications are used for treatment.

4. Parasitic Infections:
Conditions like scabies and lice are caused by parasites that burrow into the skin. These infections require prescription treatments, such as topical creams or shampoos, to eliminate the parasites.

5. Prevention and Care:
To prevent skin infections, maintain good hygiene, keep wounds clean and covered, avoid sharing personal items, and apply sunscreen to prevent skin damage. Early medical intervention is key to managing and resolving skin infections effectively.
