Swine flu is not an anomaly. We know that swine flu - like the vast majority of new outbreaks - comes from animals. We should be monitoring those animals and the humans that come into contact with them, so we can catch these viruses early, before they infect major cities and spread throughout the world.

If we can contain and monitor animal viruses at an earlier stage - when they're first entering human populations, preferably before they've had a chance to become human-adapted, certainly before they've had a chance to spread - we can head off pandemics altogether.

When there is an influenza threat, drop everything and focus on risks from influenza pandemics. When SARS spreads, focus on unknown respiratory diseases. This approach helps to quell public concern, but it's a hugely inefficient way to deal with future risks.

I usually feel like the role comes to you to sort of illuminate some piece of where you are in your life. I feel like I myself am a single woman and I'm childless - by choice - at this point, and I don't know what will happen.
