My link is no good.

"Like it or not, though, we are deeply reliant on missionary doctors and nurses. The 2008 ARHAP report found that in some sub-Saharan African countries 30 percent of health care facilities are run by religious entities. That system is crumbling due to declining funding, possibly motivated in part by growing Western suspicion of missionary medicine. We have a choice: Swallow our objections and support these facilities, spend vast sums of money to build up Africa's secular health care capacity immediately, or watch the continent drown in Ebola, HIV, and countless other disease outbreaks.
As an atheist, I try to make choices based on evidence and reason. So until we're finally ready to invest heavily in secular medicine for Africa, I suggest we stand aside and let God do His work."
