Sub-Saharan Africa is a religious place. It’s also riddled with disease. AIDS, malaria, and tuberculosis prey upon Africa’s faithful, often in the prime of their lives. And anemic public health systems can’t carry the cross. And so, into the valleys of death step medical missionaries. They are welcomed by a continent where prayer and pills often go hand in hand. And, they provide some of the best healthcare in Africa. But sometimes doctrine overrules doctor’s orders, and that can leave patients in limbo.
