One critical piece of information we do not have is, how many cases of coronavirus we are likely to see. The worst case scenario is apparently pretty bad, but perhaps efforts to contain it will be successful, and/or perhaps effective treatment protocols will be developed quickly. If the coronavirus does indeed go away by July, it will be because many competent people worked very hard to make that happen.
Normal flu has a mortality rate in the general ballpark of .01 percent, with perhaps 30-45 million cases per year in the US. And we have a vaccine for it. In a bad year, yeah maybe 65 thousand deaths.
COVID-19 may have a mortality rate as high as 6.8 percent (as of today, the tally is 2,942 deaths out of 42,746 cases that have been "closed" - meaning the patient either recovered or died). Personally, I suspect it's considerably lower, based on the theory that many of the milder cases go undocumented. A report I read earlier today which embraces the theory that the number of cases is being greatly under-reported estimates the mortality rate at .2% to .5%, which is still 20 to 50 times worse than the normal flu.
So the coronavirus apparently has a significantly higher mortality rate than the normal flu, it is apparently highly contagious, and we do not have a vaccine.
Imo a valid concern is that a widespread outbreak is not implausible, and if that happens, it would probably be far worse than the normal flu.
(Last I heard there are now two cases in California of "community transmission", meaning that the person had no known contact with an infected person and therefore apparently was infected by an unknown source, which is obviously bad news from the standpoint of containment. On the other hand, the number of new cases in China is going down, which is good news from the standpoint of containment.)
