impetigo

Impetigo contagiosa is a superficial infection of the skin. It often affects skin on the head, neck and face, and is especially common in young children. It is typically associated with yellow-ish scabs that form on open wounds or blistery areas of skin. These may itch and are highly contagious. The infection is usually caused by bacteria like staphylococcus or streptococcus bacteria. If left untreated, mild impetigo normally heals within a few weeks without scarring. Complications such as fever, or the spread of the infection to deeper skin layers and lymph nodes, are rare.
