Agree we are way too late but if you dont lockdown we may get an attack rate of 60% and a death rate of 3-4%. I will leave you to work it out. I dont think society will accept that
There is no 'control'. In the longer term we will vaccinate or treat with drugs. Meantime we have to reduce the transmission rate, currently up to 3.6, to below 1. When each patient infects less than one other person we win as the virus only survives by infecting new people. That is why early lockdown gives faster results because the pool of infected patients is lower and the virus dies out in less cycles.
I agree it is going to be more than tough. Luckily I have a medical as well as an aviation career but I am old enough to remember depressions when aviation was on its knees. It did bounce back. This is not a monetary issue. When people can re engage with each other and shop safely they will spend.
Keep safe
