the life-saving part, the heroic part has gone a lot better. people are getting more of the procedures they need. not perfect, but better. the real problem now, i think, is sort of what happens to these patients after they leave. an amputation patient in the states would be in the hospital and in an icu, perhaps, general care floor, getting rehabilitation afterwards, getting prosthetics fit, and refit. most of that is not going to happen. you were here today, anderson, that's where a lot of these patients are going to end up. >> we're going to have a lot more with sanjay throughout the hour. sanjay went over to the hospital at the threat of tuberculosis. as i said, most of the people, 500,000 people are living in these tent cities that sprung up immediately after the earthquake. we've been watching this one literally grow over our eyes over the last several weeks. literally all over the city of port-au-prince.
