the purpose of a lockdown

        [                              Robert Donovan                          ]('https://www.youtube.com/channel/UC2-9Ql0UC7NH_RfEpGGKjUA')                                                [1 week ago]('https://www.youtube.com/watch?v=289NWm85eas&lc=UgxSGGRdA2NzOsN5I-p4AaABAg')          
                  
        OK, so my understanding was that the purpose of the lock down and voluntary social distancing, washing, and all the rest, was to protect those at high risk if infected and to buy time to build up hospital capacity and get through the flu season without overwhelming the medical system, not to eradicate the virus. Somewhere along the way, people got it into their heads that the lock-down will kill the virus. Well, folks, flu season is over, and hospital capacity is loaded for bear. It's time to start building herd immunity. The only way to do that is to start lifting the lock-downs and letting people catch the disease. I have been getting ridiculed for even suggesting this. Thank you for helping me maintain my sanity.

Uhuru is trying to eradicate the virus via lockdown,and has built zero capacity. way forward is to protect the vulnerable, lift the lockdown and let the virus spread. guess mangufuli knowingly or unknowingly is on the right direction.

All you wrote is correct yet a bit off when it comes to Kenya. They have done well. The lockdown will end soon. The time taken has enabled people understand more about the disease and enhance compliance. Herd Immunity relies on among others 1. viral load 2. virulence factor 3. individual predispositions 4. Ameliorating and mitigating factors at individual and societal level.

Yes, herd immunity requires upwards of about 70% infection( I might be wrong on that). We achieve this gradually via subliminal viral loads. So, we are now better equipped in our ability to understand and respond appropriately( without being kicked in the ass). Sweden has about 7.4% herd immunity despite their cavalier approach, and that is no way far off as compared to the rest of the world. London has about 17%. I base this on the antibody tests done so far. However, none is sure whether it means no more re-infection, assuming that viruses mutate!
