The likely reason that no one from any official position is discussing the long term (length of the pandemic, total sick, total death, need for restrictions) is it is politically unpalatable. But do understand the following:
A) The "flattening of the curve" is solely to spread out the number of cases; it will not reduce by much the total number of cases over time
B) Until there is wide spread diagnostic testing for who has it now; wide spread anti body testing to show who ever had, and effective, wide spread vaccination program, social distancing is the only weapon we have in this fight
C) Therefore, a need for some level social restrictions will be necessary for the foreseeable future. Failure to do so will just bring more outbreaks
All the major models, from Imperial College London, University of Washington, Columbia University, as well as CDC/WHO, all generally agree that over the entire course of this pandemic, without any mitigation, about 1/3-1/2 of all Americans would have been infected (50-150 million) and 2.2 million Americans would have likely died. If we are at 90% effective at mitigation, 5-15 million infected and 220,000 would die. The UW model assumes complete mitigation: that is every state is "locked down" thru the end of May. Some states still have no shelter in place order; many that do have such loose restrictions that have only partial lock down effectiveness. The Columbia University model assumes partial lock down. We are creating 200,000-300,000 additional beds in field hospitals over the next 2-6 months as well as expecting existing hospitals to be able to deal with 150%-200% capacity.
However, as with the major pandemics of the 20th century (1918-1920 "Spanish Flu", 1951-1953 Polio, 1957-1959 "Hong Kong Flu" and 1967-1969 "Hong Kong" Flu) the social reaction has followed the same pattern. First (less than full) season, it hits with large social reaction. But then subsides and people become lax in behavior. Second (full season) year is usually most devastating. Third sees a tapering off as a large portion of the population has had some exposure. There is no reason whatsoever to expect a highly contagious and infections virus such as the Novel Corona will behave any differently
As for the Chinese, their centralized political, social, and economic structure as well as their experience with SARS, made them uniquely equipped to deal with this and far beyond what is possible or acceptable in the USA.
1) They had the ability and will to order a complete lockdown of an entire city of 150 and the police to enforce it.
2) they could transfer some 50,000-100,000 medical personnel to Wuhan en masse as a centralized army of health care workers
3) they could inspect all people on the street at multiple times (leaving any building, entering any building, going in to store, etc)
4) if you found with any symptoms or even had exposure, you could be taken and forcibly placed in a quarantine dorm. This was especially true with taking family members out and isolating them. Essentially anyone who had any level of disease or even suspected exposure, you were quarantined.
5) they had the central economic ability to ordered huge production of PPE and provide to all medical staff. if you saw how there assembly line ideas were also applied to how doctors/nurses were "suited up" almost like astronauts (including diapers) in 3 layers at one end of the hospital and then after shift, decontaminated at the the other end of the hospital, you would be shocked as comparison to here
Even so, China is beginning to set up quarantine and lock down in cities now as millions of Chinese start returning home. They know full well
If you want call what I say hysteria, but all the current data, the medical facts, and past history of similar events, is the reality I describe. If you think I am trying to scare people, you bet your ass I am. Its a warning, one based on on the observational evidence and not the political spin. We will be living under some sort of restrictions for sometime and ultimately, the world-wide total death toll from COVID over the next 1-3 years is likely to exceed the all the death that have ever been attributed to HIV, about 40 million
Whether you think that using medical students as "draftees" in this battle is a good idea or not, it is what will come to pass
