[Public health law in practice: violence and health in Picardy].

Violence is too often considered an inevitable part of human existence. Physical, psychological and behavioural trauma has an impact not only on the health of the individual but also on the healthcare system. Largely perceived as a social problem, violence is also a public health issue. Promoted by the World Health Organisation and developed in France by Prof Henrion, the National Authority for Health and the mission led by Dr. Tursz, the public health dimension of "Violence and health" is now better defined. The Public Health law of 2004 provided for a national plan on "Violence and Health". After an initial action study, we developed a tool to coordinate public actions in this field. The group "For health, against violence in Picardy" was created to implement expert recommendations by building knowledge, promoting training and networking, and developing services to support and guide victims of violence.
