@MagpiePi lockdowns caused harm by;
Disruption and restricted access to immediate healthcare, management of long term conditions and screening for diseases. Just this one in terms of excess deaths over the next decade could be more costly in total lives lost.
Impact on children and young people, opportunity cost of that year of no enrichment like school trips, limited socialisation, home environment pressures, mental health impact, University placement bottlenecks, substandard online "learning".
Economic costs for individuals unable to earn.
That's before you go into the individual stress, family fracture, isolation of older people.
I suppose the question to ask is, if faced with this scenario again would we support a similar type of lockdown, and under what circumstances is it advisable.
