Médecins sans frontières (MSF) or Doctors Without Borders, is an international humanitarian-aid non-governmental organization (NGO) and Nobel Peace Prize laureate, best known for its projects in war-torn regions and developing countries facing endemic diseases. It was founded in France in response to the Biafran War. The organization is known in most of the world by its localized name or simply as MSF; in Canada and the United States the name Doctors Without Borders is commonly used. In 2015 over 30,000, mostly local, doctors, nurses and other medical professionals, logistical experts, water and sanitation engineers and administrators provided medical aid in over 70 countries. These doctors and nurses decided to volunteer their time to solve issues of world health. Private donors provide about 90% of the organization's funding, while corporate donations provide the rest, giving MSF an annual budget of approximately US$750 million.
