Q&A Series #31 Q: My child developed a few blisters at the corner of his mouth since 3 days ago. They were very itchy and after he started scratching them, the blisters burst and the wound become wet. He also developed some other patches on his neck, armpit and arms. He has no history of allergies.

A: This lesion is called impetigo. A type of skin bacterial infection. It is very common in infants and children. It usually occurs around the nose and mouth areas, may also involve the body, hands and feet. It is very contagious. Therefore, early antibiotic treatment is important as it may spread to other part of the skin rather quickly. Typically, it has a honey-coloured crust after the blisters burst.
