Geir Haukursson, NetDoktor Impetigo is a common, highly infectious skin disease caused by staphylococcus bacteria or more rarely by the streptococcus bacteria. It isn't dangerous but it is an extremely contagious illness. A small red, itchy spot quickly develops into a blister containing a yellow substance. Later, the top of the blister becomes crusty and weeps while new blisters develop in the same place or on other parts of the body. Impetigo usually begins on the face, especially around the corners of the mouth, the nose and back of the ears.
Thorough skincare is important to prevent infection.
If you suspect impetigo, contact your GP as treatment should take place preferably before the child infects other children. The treatment involves washing with soap and water and letting the impetigo dry in the air. Many GPs choose to treat impetigo with bactericidal ointment but in more severe cases antibiotics are necessary. It is important to dissolve the scabs with ointment because the bacteria that cause the disease live underneath them. Small children will touch and scratch their scabs and therefore run the risk of infection.
