Inevitably. China is a vast country with huge spaces between urban settlements. Isolating parts of it is possible and they have an autocratic government well prepared to take such draconian steps. We are a tiny, densely populated island, with weak government and are obsessed with economics and individual freedoms. Widespread infection across the UK is IMO 100% inevitable now. The only hope is delayed spread, meaning the very sick can hopefully get the treatment needed, rather than just dying. Someone in the NHS (i'll dig out the quote if needs be) said a few days ago that tough choices are going to have to be made - like withholding treatment for certain people not likely to make it - so that we can prioritise those with more chance. Frankly that terrified me.
