Doctors Without Borders/Médecins Sans Frontières (MSF) aids people affected by armed conflict, epidemics, natural or man-made disasters, or exclusion from health care in more than 70 countries.

MSF volunteers raise the concerns of their patients with governments, the United Nations, other international bodies, the general public, and the media. In a wide range of circumstances, MSF volunteers have spoken out against violations of international humanitarian law they have witnessed — from Chechnya to Sudan.

Each year, MSF doctors, nurses, logisticians, water-and-sanitation experts, administrators, and other medical and non-medical professionals depart on more than 3,800 field assignments. They work alongside more than 22,500 locally hired staff to provide medical care.

In emergencies and their aftermath, MSF provides health care, rehabilitates and runs hospitals and clinics, performs surgery, battles epidemics, carries out vaccination campaigns, operates feeding centers for malnourished children, and offers mental health care. When needed, MSF also constructs wells and dispenses clean drinking water, and provides shelter materials like blankets and plastic sheeting.
