In Argentina there are more than 9000 children without parental care due to prior abuse or neglect, assisted in foster child care facilities. The quality of care provided there impacts on the well-being of children and on multiple aspects of their adult life. Prevention in health in this setting has its own characteristics. Lack of policies that guarantee good practices, not only concerns to the exercise of the right to health established by the Convention on the Rights of the Child, but also conditions the exercise of other rights. Care requires knowledge, skills and attitudes appropriate to the needs of children. The experience, difficulties and perspectives of the first health training program for foster child care facilities personnel in Argentina are presented.
