About the book

In Under the Big Tree, public health leader Ellen Agler and award-winning writer Mojie Crigler tell the moving stories of those struggling with these diseases and the life-saving work that can be—and has been—done to combat NTDs. They introduce readers to people from all walks of life—from car-washers in Lake Victoria and surgeons on motorbikes to under-resourced local non-governmental organizations (NGOs) and Big Pharma scientists—as they chronicle what has been called the largest public health program in the world.
