I cannot see the number of deaths going into the hundreds of thousands. It's not close to that across the world let alone the UK. No one would allow it to go that how even if that was the governments aim. I feel for those will lose loved ones from this. It's good to see large employers taking pro active action, working from home etc so the herd immunity tactic is unlikely to work as businesses are proactively reacting to the virus. Once the panic buying phase ends I see most normal, respectful people, keeping a distance and implementing their own social distancing regardless what the government says anyway. In reality the only way to isolate it is to stop all air travel.
