A lot will die from this in the UK, there is no doubt about that. I’d say we’ll fair better than most nations though because all British citizens have high level medical access. I’m of course concerned about old people, I have old and medically vulnerable people in my family like most.
Sensationalism in the media is to blame however for the joke we’re seeing in our supermarkets and the obvious fear people are feeling when in reality you’re very very unlikely to even contract this virus, never mind die from it. Economically we’ll suffer, the whole world will.
