Nice try, but you completely avoided answering my question...
Your question is irrelevant. Most of those other viruses (and any “out there” in a significant way at present, in terms of numbers of people infected) have different characteristics. Flu? THIS virus is much more contagious overall than any flu presently causing significant problems, it is much hardier outside the body than any flu (actually part of the “how contagious” assessment), AND it has a relatively high mortality rate, running around 3%, it appears. Last years flu(s) were about 0.075% (using “middle” estimates for the number of cases.) Plus a vaccine that can actually be given to the general populace is at least a year away, if a modestly effective vaccine can be even be developed. Even flu vaccines that mostly miss the mark usually show some lowering of fatality rates.
Now, I understand the point that a lot of “scare” is being whipped up, fears that this is some Chinese bioweapon (if it is, it’s a really poor one) run amok, imminent collapse of OUR health care system is assumed, 65 million people may die, racism rears its ugly head, some claim it’s retribution from God...
IMO, both extremes of reaction do nothing but make the problem worse by hindering our ability to properly recognize the threat and resolutely take action.
