Pretty well all of it is based on views expressed by suitably qualified virologists, so whilst no-one should ever think them infallible, I don't think any of it is actually fantasy.Some of your argument goes against the scientific evidence and some of it is fantasy.
Arriving at a death rate seems to me to be difficult. The death total here has just gone through the 10 000 level. I think comparing that with Britain is pointless inasmuch as this cannot possibly be comparing like with like.Certainly when we add first wave an second wave it will be well over 100,000 [deaths] without a doubt.
The point in the second wave is how many infected will get ill enough to need hospital treatment. In the initial wave this was about 5%. I think about 2% have needed intensive care. These rates may go down, because as those infected are ever younger, the incidence of serious illness as a proportion will decrease. This doesn't mean the healthcare system could never become overloaded, but at present this is not known; only time will tell. The infection numbers in and of themselves are not decisive.
It's been mooted here as a possibility. The quick tests could be used. It might mean having to be more specific in who gets tested, since resources are obviously limited.Testing before you go to see a relative is the idea of moonshot which is currently viewed as fantasy by most scientists.
