However, from what I hear about this virus, it is a horrible way to die so a DNR might be the kindest thing to do.
Sorry if this is not on topic, but what have you heard that makes you say that? I've only heard Trump say it was 'a violent end' and this was refuted by NHS staff who are doing their usual palliative care and keeping dying people comfortable.
However, I agree with the assessment that DNR is probably kindest. DNR doesn't prevent palliative care being administered at home (or in care home). It's only resuscitation, but you can also specify to not be hospitalised. For a PWD this is almost certainly best, especially now when you cannot be accompanied.
My dad took a good day when a dr said he had capacity to insist he does not want a DNR filed.
This is quite aside, apparently, from his Christian scientist views that surface every time he's given a laxative or his prescribed donepezil.
(It's also a different story to what he told me years ago when he was well, but dementia has given him a zest for life previously unknown to us all, apparently.)
However, given the circumstances, I think they would likely keep him in the home if he caught it - which is pretty unlikely given the spread in his area is not high and it's a small home.
