Many factors have conspired to make this cholera outbreak one of the worst ever seen in Angola. But with what we know today there can be no excuse for not doing everything humanly possible to prevent the death toll from climbing much higher.

one of the worst hospital scenes I have seen in my 20 years of doing humanitarian relief.

A vivid picture. One of the worst things I have seen.

It was one of the worst and most debilitating scenes.

That was horrendous. That one drive may have been the worst I have ever seen. I think we had 10 missed tackles in six plays (actually four plays). We have a long way to go.

This is the worst disaster of my 32 years I've ever seen that's this bad. I've been through a lot of hurricanes and disaster services. This is a war zone. It is horrid. People's lives are just — everything they've worked for their entire lives is absolutely gone.
