Sexual abuse against children is common. Both medical and social workers must understand the conditions which suggest the possibility of sexual abuse. To protect children from further abuse and prevent future psychological sequellae, it is necessary to make a multidisciplinary assessment, which is usually followed by referral to justice or to the children's protective services. Legislation concerning medical confidentiality must be well-known and understood by physicians. If the child is left in his family, supportive measures may help him and his family to modify interrelations. If he is sent away from his family, to a foster home or to a foster family, it is very important to maintain the bonds between the child and his family.
