Development aid in five easy steps

Almost all of these deaths are in the world's poorest countries. Ending these deaths would not only reduce suffering, but would also unleash economic prosperity in impoverished and unstable societies.

The greatest barrier to doing so is that the poorest countries can't afford universal primary health care, even though the cost per person is very low. Using immunisations, modern medicines, state-of-the-art diagnostics, mobile phones, and other new technologies, universal primary health care is now highly effective and very inexpensive, costing around $54 per person per year in the poorest countries.
