【简答题】
Fill in each blank with no more than three words based on your listening of Bill Gates' TED talk. Today the greatest risk of global catastrophe doesn't look like this. Instead, it looks like this. If anything kills over 10 million people in the next few decades, it's most likely to be a highly _____1______ rather than a war. Not missiles, but microbes. Now, part of the reason for this is that we've invested a huge amount in nuclear deterrents. But we've actually invested very little in a system to stop an _____2_____. We're not ready for the next epidemic. Let's look at Ebola. I'm sure all of you read about it in the newspaper, lots of tough challenges. I followed it carefully through the case analysis tools we use to ____3____ polio eradication. And as you look at what went on, the problem wasn't that there was a system that didn't work well enough, the problem was that we didn't have a system at all. In fact, there's some pretty obvious key missing pieces. We didn't have a group of epidemiologists ready to go, who would have gone, seen what the disease was, seen how far it had spread. The case reports came in on paper. It was very ____4_____ before they were put online and they were extremely _____5____. We didn't have a medical team ready to go. We didn't have a way of preparing people. Now, Médecins Sans Frontières did a great job orchestrating volunteers. But even so, we were far slower than we should have been getting the thousands of workers into these countries. And a large epidemic would require us to have hundreds of thousands of workers. There was no one there to look at ______6______. No one to look at the diagnostics. No one to figure out what tools should be used. As an example, we could have taken the blood of survivors, processed it, and put that plasma back in people to protect them. But that was never tried. So there was a lot that was missing. And these things are really a ______7_____. The WHO is funded to monitor epidemics, but not to do these things I talked about. Now, in the movies it's quite different. There's a group of handsome epidemiologists ready to go, they move in, they save the day, but that's just pure Hollywood. The failure to prepare could allow the next epidemic to be ________8_______ than Ebola Let's look at the progression of Ebola over this year. About 10,000 people died, and nearly all were in the three West African countries. There's three reasons why it didn't spread more.
