graybeard,
The difference here is that the rate of growth for this new critter is amazingly fast. 10 to 60 times faster than the average flu virus. Add to that, it is quite severe and has a very high mortality rate for some groups of people, and you have something that is in another league.

You are right about the those shortcomings issues, but we didn't need an epidemic to see that.
