Here’s my take after reading and listening to as much as possible on the commute the last couple weeks.
We will all get Covid19 at some point and it will seem normal. We are still passing around the Spanish Flu of 1918, we’ve all had it most likely. We have some herd immunity to flu, none to the corona virus. We have medications known to combat flu, not yet for Coronavirus, I’m sure we will soon.
We don’t know if it will die down during the summer, but hopefully it will. At some point this will just be another flu, pain in the butt, but no big deal. But that point will come after we have vaccines, meds known to combat it, and some immunity. 50% of the population get flu vaccines, 0% have a vaccine to this, so if it should spread as far and wide, it won’t be pretty.
The biggest problem i see is the major complication rate filling hospital beds, overflowing our capacity to treat.
A few numbers
Serious Complications requiring hospitalization (pneumonia etc) flu .9%, CV 18%
Requires ICU Flu .25%, CV 5%
Case fatality flu .1%, CV 2.3% worldwide (not really enough data to know US yet, could be less due to undiagnosed cases)
Rate of infection Ro(R naught). Flu 1.3, CV 4.7, (Smallpox is 5-7)
Lives on surfaces flu 4-5 hours, CV 5-9 days(current info, could change)
Incubation time flu 2-3 days, CV 5-14 days
ICU per million infected flu 9000, CV 180,000
Fatality per million infected flu 1000, CV 23,000
So the point is at some point this will be just another cold season, but right now it could easily overwhelm the system if it spreads as easily as they believe.
For one thing, Americans aren’t going to stand for a city or huge area to be roped off and quarantined like China. I mean I would like to fence of Seattle, but that has nothing to do with the virus

.
In the mean time it will slow the economies just by people not buying cruises, airplane tickets, concert tickets. I mean airlines are canceling sole flights due to lack of travel, movies postponed, 3/4 of people surveyed wouldn’t take a free cruise. 2/3’s of our economy is us spending, so I don’t see this year as being real stellar investment wise.
