I worry about the prospect of a virus emerging that has a much worse cfr. some virus can have 10 - 50 % cfr which would cause chaos in society. I really hope if this happens the government will have learned to shut borders immediately and implement full lockdowns straight away or whatever is necessary to get a grip on virus before it spreads. If you look at other countries such as Vietnam who have contained things so well whereas we have just allowed it to spread until the public are now almost giving up on the restrictions in place. We need to learn from other countries next time.
