There seem to be a number of groups in the population at greater risk than others. These include primarily the over 70s and those shielding of any age.
Others possibly at greater risk include BAME people, obese people, people in certain blood groups. We understand research is ongoing regarding these groups.
Then there's anyone not in the above groups, for whom it would appear that the risk is less.
So logically those of us in the first group need to be especially careful. Those in the second group must be in something of a quandary, as not enough is known about why these groups seem to be suffering disproportionately.
But for the majority, most of whom will be of working/school age, perhaps it is time to relax the 2 metre rule.
Based on this, can't we all make our own decisions about risk?
