Our public health doctors don't have a 'dog in the fight' either. What no one is discussing is when you stop quarantine, once you have started? This virus could go on for months, it could be seasonal and be back in November/December, or it could disappear in the spring. As with the question I posed about Italy, assume we lock down the UK for 3 weeks, what next? Stop any travel in or out? Assuming not, what happens when someone travels in from a place that then declares it has virus a week later? Shutdown for 3 weeks again? If we don't time this right, we could be doing it in perpetuity.
