Which skin disease is caused by bacteria?

Impetigo is caused by bacteria, specifically Staphylococcus aureus or Streptococcus pyogenes. This highly contagious skin infection commonly manifests in children and is characterized by red sores that quickly ooze and form a yellow-brown crust. It often occurs on the face, especially around the nose and mouth, and can spread through direct contact or by sharing personal items such as towels or skin products.

Understanding the nature of the bacteria involved in impetigo is crucial for both diagnosis and treatment. Antibiotics are typically required to eliminate the infection and prevent its spread.

The other options listed refer to conditions caused by different pathogens. Scabies is caused by a mite infestation, tinea capitis is a fungal infection of the scalp, and herpes zoster is caused by the reactivation of the varicella-zoster virus, which is a viral infection. Each of these conditions requires a different approach to treatment, unlike impetigo, which specifically involves bacterial pathogens.
