Hello
@Brother47
Having a daily phone call is good practice as far as the care home is concerned and a cause to be grateful.
When the medical staff say he is comfortable it means precisely what it is. Your brother is pain free and comfortable. That is their main concern.
When the care staff say your brother is absolutely fine they mean the same as the medical staff only they are using less medical language. Your brother is pain free and comfortable.
We all know how infection can have a more damaging effect on people with dementia than on those without and I for one would be grateful to hear he is sleeping a lot. There are other far worse reactions to covid , especially breathing difficulties which I wouldn`t wish on anyone.
We also all know how appetitive is the first thing to be affected when we are ill.
It`s a very sad state of affairs and much harder when you are unable to visit and see for yourself but it sounds to me as if your brother is being carefully monitored and very well cared for.
