Suicide is a serious global public health issue. It is among the top twenty leading causes of death worldwide, with more deaths due to suicide than to malaria, breast cancer, or war and homicide. Close to 800 000 people die by suicide every year. The reduction of suicide mortality has been prioritized by the World Health Organization (WHO) as a global target and included as an indicator in the United Nations Sustainable Development Goals (SDGs) under target 3.4 (see Box 1), the WHO 13th General Programme of Work 2019-20231 and the WHO Mental Health Action Plan 2013-2030.2 A comprehensive and coordinated response to suicide prevention is critical to ensure that the tragedy of suicide does not continue to cost lives and affect many millions of people through the loss of loved ones or suicide attempts.
