I get what you are saying, but keep this in mind....IF the Brit's report, with specific regard to the projections illustrated by the figure that I posted, we do, in fact, avoid a catastrophic failure of the Health Care system IF the more stringent NPI protocol is enforced AND it is enforced for an extended period of time - that is MORE than the 5 months shown on the illustration of the model. IF the NPI is released after 5 months, the re-occurrence of the infection along with the assured failure of the Health Care system is predicted to happen shortly after the NPI is withdrawn.
THAT is the most sobering aspect of the report to me. One conclusion is that the stringent NPI HAS to be in effect for more than 5 months (how long??) unless an effective PI is deployed.
Further, the suggestion [is] that the same would occur anywhere that the stringent NPI has been relaxed. So, one might wonder, has the NPI been relaxed in South Korea, for example? Get what I am saying/asking?
Correct, albeit it would be hard and premature to stick a number on it. But measures will need to be applied for months, not just weeks.
And there's many unknowns, like general population health and immune response. But, on average, people are the same whichever side of the globe. The phantom of "we have a better a health care" will hit hard, as no health care system will be able to cope with the load of a free SARS-Cov-2 virus spread. Just look at what happened to other countries so far and their high healthcare quality standards.
But regardless of how accurate the report predictions really are, the NPI protocol will have to be very strict, in relative terms. Always a multiple stricter than what appears needed as given by the current figures, due to the reasons I've listed before. And there is the challenge, to get public opinion behind such measures without a readily observable facts in proximity. People are typically only willing to act based on current facts, not on impending trouble, even if it's just two weeks ahead.
The other part of your discussion, relaxing the NPI, is what I would call the phase two problem. Over here, this still has to come and China is about to enter it. I've seen statistics of previous old epidemics of the past which suggest that when measures are released too quickly, you effectively get a second, even higher, infection peak. So that's a very real worry indeed. And it will happen, people will feel "it's over and I want to get out now".
But, these would be "trouble for later", as we're all in the first phase of containment now and regarding the US, it still has to enter it the coming days/weeks.
However, regions which had a bad phase one, should have a less troublesome phase two, as their group immunity will be better.
Basically, as I've said before, there's two extreme options in the spectrum, none of which are realistic:
- Let nature do its thing and let the virus freely spread. Expect extreme cruelty from a society point of view, all weakest will die without medical care due to health infrastructure overload, with the benefit of very rapid group immunity and this "being over soon".
- Halt all personal contact and activity, and quarantaine everyone, without a single citizen disobeying. No group immunity but with the benefit of potentially ending virus spread before it progresses.
All realistic options are in between those. The more you go toward the last option, the longer the NPI measures period becomes and the less it will stress health care infrastructure, at the expense of economical distress.
