Impetigo is a relatively common bacterial skin disease, which particularly affects young children and even adults. Highly contagious and often responsible for school outbreaks, impetigo is a benign disease. It can be caused by two different bacteria, streptococcus and/or staphylococcus. The latter often enter into contact with skin areas already affected and weakened by a prior injury (scratches, insect bites, cuts, eczema ...).


Impetigo usually appears initially in the face close to the nose and mouth. But it can also extend to the scalp, buttocks or arms and legs, mainly via self-contamination (by scratching sores). These rashes take the form of clusters of reddish pimples. The blisters then begin to ooze, burst and ultimately dry and are covered with a yellowish crust. The lesions are usually not painful. In infants the disease is quite characteristic with lesions resembling bubbles of about 1 cm that tend to spread quickly.


Diagnosis is usually clinical. A sample is taken in cases of doubt.


It is important to implement measures of good hygiene to avoid the risk of spreading the rash to other parts of the body and or to other people. For children, it is advised to wash them twice a day with antiseptic soap for a week to ten days. It is also advisable to regularly change their clothes to prevent them from further damaging their skin. It is also recommended to take the child out of school for a few days. If these measures are not enough, your doctor may prescribe antibiotics.

Again, avoiding the risk of impetigo involves good personal hygiene, including regular cleaning of small skin lesions where impetigo spreads more easily. And of course, it is important to avoid contact with someone who is already infected.
