Liz I think that the fact that you are asking means that you know that you shouldn’t do it, it isn’t a life or death situation so you should stay away, what if you are carrying the virus? You will go back into their home and take it with you.
Morethan you are in an awful situation, I think you have to follow your gut on this one, maybe I’ve in with them for the duration, I’m sure for exceptional circumstances you would be ok, but are you absolutely fit and well yourself?
I saw yesterday that anyone having end of life care can have one close relative with them ( in our hospital anyway) not sure if this applies to Covid 19 patients as they are sedated anyway.
I hope you come to a decision and that it all goes as well as it can for you.
