Impetigo

Impetigo is a superficial skin infection with bacteria (usually staphylococcus, but sometimes streptococcus).

The bacteria cause crusty, honey-coloured scabs. There may also be blisters, in which case we speak of ‘impetigo bullosa’.

The infection usually affects the face around the nose and mouth, but there can be lesions on the body.

Impetigo does not usually cause general symptoms of illness.

Impetigo occurs mostly in children and is extremely contagious. For example, there can be an upsurge or outbreaks in schools or day-care centres. Adults can also experience impetigo, but that is less likely. The skin infection occurs frequently when the skin is damaged (e.g. eczema or chickenpox).

The dermatologist diagnoses impetigo by sight. Sometimes, the physician will also take a skin swab to determine precisely which bacteria are involved and whether they will be treatment-responsive.

• Mild cases: topical antibacterial agents, such as disinfectants and bactericidal creams.
• More extensive cases: a course of antibiotics in pill form or syrup.
