Samuel Kargbo, better known as Dr SAS, is credited with helping turn the tide of the Ebola epidemic in Sierra Leone. He realized that local tribal burial practices led to spreading of Ebola after an infected person had died, and so he brokered a compromise between health professionals and tribal elders. He tried village leaders in safe burial practices and enabled them to provide a modified form of the usual rituals for the dead.
