Bacterial inflammation of the skin, most common in children but occurring also in adults in unfavourable circum- stances. The disease is highly infectious, particularly if hygiene is deficient, although modern improvements in this field have much reduced the incidence of the disease. The first phase usually consists of small, suppurating blisters on the face which burst quickly. The most characteristic symptom of impetigo is the honey-coloured crust which during the second phase wholly or partly covers the affected area. There are various forms of impetigo, which differ from the above in varying degrees. In adults the condition almost always affects skin areas previously damaged by a skin disease, and is thus a complication of eczema or cheilosis. The skin can also be damaged by scratching of very itchy conditions. Impetigo can be treated with disinfectant or antibiotic ointment. If the condition is extremely widespread, antibiotics may have to be administered as capsules or in liquid form.
