Ibola had some different characteristics, but you couldn't tell about this one at a time. Ibola kills e people faster and more effectively. It kills a number of carriers, ok? This one doesn't. So thisis, you know, but things can change. And we don't have to worry too much about pandemics, because i have to have a good mechanism. The average of the past 12 pandemics is a poor predictor of what do expect the next one.
