Those who dont learn from history are doomed to repeat it.
I'm not sure that the British public were quite as compliant in WW2 as suggested but even if they were things have changed. Children are now raised very differently and have expectations that were not present when I was young. The public also have, with a lot of justification, considerably less trust in politicians. Our government not only fail to lead by example they are seen and known to fail.
The government insisted on a national lockdown. I understand the rationale for this - people fleeing the most infected part of other countries e.g. Italy spread the virus - but it did inflate the economic damage. It would have been sensible to ban travel but allow the south west more freedom, since it was not significantly affected (apart from torbay) early on. There was no logical reason to close non-essential businesses in areas with low levels of disease.
Another reminder, however, that it was not only London hit hard www.bbc.co.uk/news/uk-wales-52263285 and had travel bans not been imposed that the rest of Britain would have rapidly followed. Indeed other major connurbations with international airports were still hit fairly hard not much later than London. The national lockdown meant such areas were able to benefit from the rapid learning in London about how to manage the disease and the death rate was probably slightly lower as a result. If there is a second wave areas that will suffer most (like the south west because they have few people with antibodies) will still have a lower death rate because of experience gained in treating this disease.
Had the government banned travel (and hence mass events) a week earlier and imposed strict lockdown only in heavily affected areas economic damage would have been considerably reduced. If they had adequately prepared by stockpiling PPE both deaths and economic damage would have been reduced. If they had relaxed some restrictions (garden centres, outdoor attractions) earlier economic damage would have been reduced. Furlough was helpful, though - kept money in the economy.
Locking down a week earlier would have meant restrictions could have been relaxed sooner and more fully for the summer.
Incidentally the research study that mentioned the bradykinin storm also mentions another plausible method by which vitamin D may influence this disease. Our government has failed to include this in intervention studies, a failure that is incomprehensible. I shall be back on vitamin D tablets soon.
