Stop going off on so many tangents, Yorgo. I haven't got the foggiest idea what you think or what you don't think. Simple facts:
1 Yes, the disease COVID-19 is caused by a virus, specifically SARS-CoV-2. Anybody who says it is not is an idiot, i.e. IQ between 0 and 10.
2 Yes it is a pandemic. It is infectious and it is spreading worldwide. That is what a pandemic is.
3 Yes it is killing people. The exact absolute case fatality rate is not known because some people are asymptomatic and are not detected.
4 The case fatality rate increases with increasing age and is very significant in the oldest age group.
5 Despite some uncertainty in the case fatality rate it is known to be much higher than seasonal flu.
I have already said what the strategy should be:
1 Reduce the infection rate to zero and hold it there through test-trace-isolate. You might need some restrictions on people mingling freely but they ought to be minimal, i.e. highest risk environments.
2 If you don't have the capacity to achieve item 1 use broad restrictions on people mingling with other people in order to reduce the infection rate so that it is within your capacity. Increasing your capacity is very useful but once the infection rate exceeds your capacity you will never increase your capacity fast enough to catch up. Only movement restrictions will work.
3 If you have to adopt Item 2 the restrictions should aim to stop the increase in infection rate and reduce it as fast as possible. That means you need to impose drastic restrictions and impose them very rapidly.
The UK tried to use Item 1 at the very beginning and failed. They did not increase the capacity fast enough to stay ahead of the virus. Other countries like Taiwan and South Korea did succeed and had much lower deaths as a result.
The UK then applied Item 2 and failed again. They were too slow to respond, the measures were not rigorous enough and enforcement was poor. That resulted in a very high peak, a very slow fall and a very large number of deaths. New Zealand applied Item 2 very successfully and had a very low peak, a very fast fall and very few deaths. Greece also applied Item 2 quite well with similar results to New Zealand but not quite as good.
The UK then increased its test and trace regime as it should. Unfortunately it overestimated the capacity of the regime and started to remove restrictive measures before the infection rate was within the capacity. More importantly it never really got a handle on the isolate part. It relied entirely on everybody complying with virtually no checks and no enforcement. Greece certainly got the infection rate down to a very low level but it didn't do much better than the UK at test-trace-isolate. Like the UK the fastest rate of spread was amongst the young but unlike the UK there is far more mingling between young and old in household environments, i.e. multi-generational families, so the death rate relative to infection rate is higher in Greece. Greece's deaths relative to detected infections is over double that in the UK. On the other hand the UK has 5 times the number of detected cases per million population over the whole pandemic than Greece although, to be fair, it has carried out almost 3 times as many test per million population.
So I have laid out the known facts and I have said what I think the strategy should be and where it has gone wrong. I have been saying the same thing for months. What would you do?
PS If you want an analogy I see the whole sequence as a number of people in a canoe going down the Niagara river arguing about at which point they should turn round and paddle back. Having never reached an agreement I see them now in mid air about halfway down the falls still arguing about when they should start paddling back. I think we all know the outcome.
PPS I also think that I hear the fluttering of the wings of a black swan.
