Medical neutrality refers to a principle of noninterference with medical services in times of armed conflict and civil unrest: physicians must be allowed to care for the sick and wounded, and soldiers must receive care regardless of their political affiliations; all parties must refrain from attacking and misusing medical facilities, transport, and personnel. Concepts comprising the principles of medical neutrality derive from international human rights law, medical ethics and humanitarian law. Medical neutrality may be thought of as a kind of social contract that obligates societies to protect medical personnel in both times of war and peace, and obligates medical personnel to treat all individuals regardless of religion, race, ethnicity, or political affiliation. Violations of medical neutrality constitute crimes outlined in the Geneva Conventions.
