I can't think of a better model for Haiti rebuilding than Rwanda.

If any country was a mine-shaft canary for the reintroduction of cholera, it was Haiti - and we knew it. And in retrospect, more should have been done to prepare for cholera... which can spread like wildfire in Haiti... This was a big rebuke to all of us working in public health and health care in Haiti.

I've been asked a lot for my view on American health care. Well, 'it would be a good idea,' to quote Gandhi.

I recommend the same therapies for all humans with HIV. There is no reason to believe that physiologic responses to therapy will vary across lines of class, culture, race or nationality.

I think that looking forward it's easy to imagine more constructive help for Haiti.

For me, an area of moral clarity is: you're in front of someone who's suffering and you have the tools at your disposal to alleviate that suffering or even eradicate it, and you act.

That's when I feel most alive, when I'm helping people.
