Violence against women – particularly intimate partner violence and sexual violence – is a major public health problem and a violation of women's human rights. Estimates published by WHO indicate that globally about 1 in 3 (30%) of women worldwide have been subjected to either physical and/or sexual intimate partner violence or non-partner sexual violence in their lifetime. Most of this violence is intimate partner violence. Worldwide, almost one third (27%) of women aged 15-49 years who have been in a relationship report that they have been subjected to some form of physical and/or sexual violence by their intimate partner. Violence can negatively affect women’s physical, mental, sexual, and reproductive health, and may increase the risk of acquiring HIV in some settings. Violence against women is preventable. The health sector has an important role to play to provide comprehensive health care to women subjected to violence, and as an entry point for referring women to other support services they may need
