At the global level, there are many countries marked by violence affecting health care. The 'Health care in danger' project aims to establish practical measures and recommendations that can be implemented on the ground by policy-makers, humanitarian organizations and health professionals. In view of the multiplicity of actors and latitudes concerned, it is essential to be able to make available the tools needed to make informed decisions, guide behaviour in high-risk areas and provide everyone the means to create and optimize the dialogue between humanitarian professionals and health on the one hand and relevant authorities or other armed actors. This course covers various topics such as ethics, rights and responsibilities of the staff of health and pre-hospital personnel, issues related to international law and humanitarian law, international human rights, caregivers and patient safety as well as the role of communities to address and reduce violence against health care.
