I strongly believe C19 was active in the UK in December and January 2020, long before officially known. My family and neighbours and friends experienced illnesses similar to C19 symptoms during this period and I attended two funerals in first two months of this year, someone I spoke to had attended four. Do you share a similar experience at the start of this year? Majority of deaths have victims who were/are elderly and those with "underlying health issues". If I am correct, official selective antibody testing should undertaken nationwide to establish the facts. Has herd immunity already occurred? Then let the rest of the public purchase their own antibody tests, let them feed in the results data online, build in a margin of 30/40% of error. Those in the vulnerable category have to remain isolated, supported by neighbours and family. The rest take their chance, if you have immunity get on with your life, if you don`t and are healthy, your choice is take a chance of getting C19 and surviving or perhaps not surviving. We have to hope for a vaccine by the end of 2020.
The world economy is being trashed, is heading for a depression, and yes lockdown must end soon to prevent not only civil disorder but an economic meltdown which will very quickly lead to it in any event
