Genuine question - why does the R rate need to stay below 1 for a less deadly variant?
a) we don't yet know whether it's less deadly, or (crucially) if it is, then by how much?
b) a small percentage of a big number is bigger than a larger percentag of a big number
c) that small percentage could be enough to over-stress the NHS, which is still a dreadful outcome
We need to be watch hospital admissions figures, rather than case numbers.
And it would be beyond reckless to take anything other than a precautionary approach for the first few weeks. Because if itncauses twice as many cases as previous variants, but is only a third less serious, then we're in big trouble. And even worse trouble if we give it an easy ride in terms of trajectory of early rises.
