A contagious bacterial infection characterized by open lesions found by the nose and/or mouth:

• A. Acne rosacea
• B. Dermatitis
• C. Hepatitis
• D. Impetigo

Answer: (D)

A contagious bacterial skin infection with open lesions around the nose and mouth points to impetigo. It typically starts as small red spots that quickly develop into vesicles or pustules on the face, which then rupture and leave thick, honey-colored crusts. The condition is highly contagious and spreads through direct skin contact or shared items, which is especially common in children. Impetigo is usually caused by Staphylococcus aureus or Streptococcus pyogenes, which explains its rapid contagious spread and crusting pattern. Other options don’t fit this presentation: acne rosacea involves persistent facial redness and bumps rather than contagious crusted lesions; dermatitis is an inflammatory rash that isn’t characteristically contagious or crusted in this way; hepatitis is a liver disease and does not present as a facial skin infection with crusted lesions.
