Domestic violences are very common and constitute a criminal offence. Women are mainly victims but can also be perpetrators. Domestic violences have a major health impact on people, families and society. The primary care physician holds a major role in the targeted detection of domestic violences and their prevention. He must know their specificities and adapt his response according to the situations. This specific response does not prevent a rational approach: we propose to distinguish between different types of women's vulnerability. Management must involve an efficient network taking into account individual, family, community and social factors. In this context, use of regularly updated information from official websites is mandatory.
