'In 1976 I discovered Ebola, now I fear an unimaginable tragedy'
"Peter Piot was a researcher at a lab in Antwerp when a pilot brought him a blood sample from a Belgian nun who had fallen mysteriously ill in Zaire."
"I think it is what people call a perfect storm: when every individual circumstance is a bit worse than normal and they then combine to create a disaster. And with this epidemic there were many factors that were disadvantageous from the very beginning.
Some of the countries involved were just emerging from terrible civil wars, many of their doctors had fled and their healthcare systems had collapsed. In all of Liberia, for example, there were only 51 doctors in 2010, and many of them have since died of Ebola."

(I've googled Sierra Leone slums, Lagos slums, Liberia slums, etc. The images are simply heartbreaking. The terrible conditions these poor people have to contend with every single day of their lives is beyond anything we in the west could imagine.)
