The stats I've heard from seemingly reputable sources imply that ~80% of population that might get this will simply "ride it out" like the flu experience we've all, uh, experienced, and recover just fine. The other 20% are the unlucky ones that may struggle getting through this, needing medical interventions, the level of which could be moderate to severe based on the individual's various specific instance, health, age, etc.
IMHO there's a dramatic and likely unwarranted degree of panic going on, but I fear expressing that opinion openly because when I do, I'm met with a backlash of disbelief, implications of my ignorance and I get headline-stats thrown at me without validation or vetting that I am somehow supposed to rebuke on the spot. I have already had more than enough people throw 'facts' out (pets can get and transmit being just one example) that I have easily found WHO-based statements (World Health Org, not Pete 'n Roger) saying otherwise. But, everybody believes their opinion is truth, inherently, and defend it as a reflex. Myself included. (Sidebar: good article by Michael Shermer)
I consider this all to be one more sign that Idiocracy was a documentary and that our nation has lost it's fucking mind (right behind Trump not only being in office but likely to remain another term). Panicking yourself over the possible economic panic of others only brings about the economic collapse you're worried about. It's completely self-inflicted.
It's definitely happening, though. And I don't consider most of it necessary or productive. Schools closing, bans on large crowds, panic shopping.. it's out of control. Yes, I do want to protect my 81yr old mom's health, since she's at high risk. Thus, I have told her I will shop for her as her needs arise. She'll give me a list, a bit of notice, and I'll buy it and take it to her. It'll keep her out of the insanity, including keeping her away from all those who are panic-shopping to prepare for a possible virus spread. They are, themselves, willingly and consciously entering massive enclosed building filled with possible carriers. The virus that might eventually infect them may be contracted while scrambling amongst dozens of others grabbing toilet paper packages off of Costco pallets. Well played.
I'm hoping that the 'full blown aggressive' move this is proving to be makes short work of things, and that the world calls the hell down and returns to a somewhat normal in a few weeks. Perhaps slamming the brakes will be more effective than coming to a gradual stop. And when we get back to our lives, it might be with a bit more sanitary sanity.
Alternatively, I also have to wonder if nature decided it wants to wipe out a percentage of the dysfunctional and destructive population on this massively overcrowded organism called "earth"…., should we be intervening? Who made us … "God"? Maybe the herd needs thinning. Nobody wants to die, everybody will, we just seem to feel entitled to delay it against the natural order of things. Perhaps that's not the right move. Food for thought.
