Oh cool it's that simple, all we need to do is get everyone to wash their hands, while we're at it, let's get everyone to eat their vegetables too.
By your own statements everyone is NOT washing their hands, so the virus WILL spread, everyone knows it will spread and there is no plan on what will be done AS IT SPREADS!
And by 'what will be done' I don't mean "find a cure" (although you know, do that). I mean how do we keep society functioning on both a macro but more importantly on a micro level until everything is back to normal.
I can do everything I can to make sure I don't get it, but what am I suppose to do if everyone in my office get's it. Even if I am fine, the office might shut down. Not everyone is paid a monthly salary some people are paid hourly and only hours that they actually work (no holidays, no sick leave) if the office is closed many people don't get paid, what's the plan to deal with that?
What if schools close? Are parents suppose to stay home with their children? Will they be compensated? Will their jobs be protected? Etc. Etc. Etc. What's the plan to deal with that?
If travel is already shutting down, that means it is likely more travel will either shut down or at least be delayed as it spreads, what does that mean for commerce? Especially food, if we see even a small delay in food arrivals it will be devastating. What's the plan to deal with that?
And there are a million other little things we take for granted but our society would cease to function as we know it if there is just a small temporary change and no plan on how to deal with it.
Again my concern is less about the actual virus, and more about how this will effect us socially and economically, the CDC does not have any answers on that because that's not their job.
If things start shutting down it will have a domino effect, and right now the answer is "Well we have no plan to make sure things don't shut down, and if they do shut down we have no plan on how to stop the domino effect, but hey spring is coming, we're sure everything will be fine."
