If we're talking about the pandemic H1N1 influenza, just to be clear, there is a whole set of strategies and actions that are needed to reduce the morbidity and mortality that we may anticipate from the next wave of this. Good health, being as healthy as you can, having your chronic medical conditions well looked after, knowing about measures to reduce the spread of disease, all of these things are important. And it's useful to divide them into two categories.
One is reducing the probability of getting exposed to the virus, and that has to do with crowded housing, handwashing, knowing how to conduct yourself in social settings to reduce the risk of exposing others to the virus. So there's that whole category.
But it's a different question from the question of, if you do get the flu--and we have to expect that many of us, no matter where we live, are going to be exposed to the flu; it's a very difficult virus to contain--who's more likely to have severe disease and need intensive care and die? It's a really important question. That has more to do with chronic health conditions—we've talked about that already—it has to do with getting appropriate and timely care if you are in that very small percentage of people who go on to get pneumonia or severe complications. For those people who we think we can help with early use of antivirals when they first get even mild symptoms, if they have those risk conditions, it means having access to that. And it means, on both sides of the table, an educated, enlightened public who know when to access health services and a ready health system that's there to receive them and give them appropriate care.
I could speak more about what some of those dimensions are, but I wouldn't want to oversimplify the issue to be either one of prevention or one of treatment. It's really a combination of both.
