Impetigo is a skin infection caused by bacteria, most commonly Staphylococcus or Streptococcus. Impetigo develops if the bacteria gets into the skin and multiply. Impetigo is more likely to develop when the skin has a poor barrier function or when its immune system is impaired, for example in children with eczema. Impetigo may also develop in children with poor skin hygiene or from contact with someone with infected skin.
Impetigo may appear as painful or irritating blisters, sores or yellow crusts stuck to the skin. It appears commonly on the face and limbs, but can develop anywhere.
Treatment
Impetigo is treated with oral antibiotics. It is important to complete the course of antibiotics prescribed by your doctor. Discourage children from touching affected areas of skin and encourage them to wash their hands frequently. They should not share towels or bedding. Impetigo is contagious. Children should be kept away from school or nursery until they have no new skin lesions and all the old lesions have dried up.
