How so? The list looks the same for diabetes (middle group). The only changes I can see are bmi of over 40 has been added to the vulnerable (middle) group.
Not overly sure what the purpose of this middle group is though other than it may raise the level of caution of some people within it. It doesn’t force employers to consider your risks any more than jo public (although hopefully some do), nor allow you access to supermarket online delivery slots or to receive a carb laden box of dubious goodies to enable you to take the social distancing as seriously as advised (unlike the extremely vulnerable shielded people - who justifiably need this). Nor make any other practical difference to most within it. It does allow us to worry more though.
Sorry, that's what I meant. I haven't seen it say "clinically" vulnerable before and I'm sure it reiterates staying name a bit more. Apologies if it causes concern I'll remove the post or a mod can if it's deemed as confusing or over concerning.
