Well see Randy's article and just think it through... If case numbers are dropping in the capital despite the heavy amount of foot traffic it shows that this thing had been ripping through London in Feb and march.. by the time lockdown was imposed the peak had passed. All the lockdown has achieved IF this trend continues is to have made the tail last longer despite the hospital's never being overwhelmed (remember the only reason for lockdown).
From Randy's article:
'I hope the intervention did not have too much of an impact because it most likely made the situation worse. The intervention was to ‘flatten the curve’. That means that there would be the same number of cases but spread out over a longer period of time, because otherwise the hospitals would not have enough capacity.
Now, as we know, children and young adults do not end up in hospitals. It is only those who are both elderly and have comorbidities that do. Therefore you have to protect the elderly and the nursing homes. The ideal approach would be to simply shut the door of the nursing homes and keep the personnel and the elderly locked in for a certain amount of time, and pay the staff overtime to stay there for 24 hours per day.
How long can you do that for? For three weeks, that is possible. For 18 months, it is not. The flattening of the curve, the prolongation of the epidemic, makes it more difficult to protect the elderly, who are at risk. More of the elderly people become infected, and we have more deaths.'
