That's fabulous that he's come back to stay, clearly your kindness & hospitality is what he likes in your home.
Are you comfortable in your own home knowing he may potentially be exposed to Covid19?
I don't expect an answer to that question as that's both of your private business.
In general terms, To clarify, when I mentioned Doctor of quackery I definitely don't mean the Doctors at the coalface working face to face with patients in hospitals or Doctors rooms as they adhere, generally, to a Duty of Care and Hippocratic Oath.
I was refering to that of those who are / have Doctorates of Academia who at times are university students/ professors who are acting outside of their Scope of Practice, knowledge & legal qualifications who don't have one on one first hand experience with patients or intimate knowledge of medical history.
I've utmost respect for those working at the coalface with patients and recall when the Boxing Day Tsunami occured "Doctors without Borders" did the most incredible jobs in very challenging circumstances, as they continue to do so across the world.
They certainly didn't have any 2metre rules, nor would they dare try impose them & not treat vulnerable people because of their status.
You may recall the status of some of those people were horrific as they were left dying & decaying in the weather elements which created the possibility of infectious diseases.
No person with health issues needs to be stigmatized in the way so many have been & I personally think it's sad people have been.
If one has existing health matters and opening one's home it's natural to be cautious in the current circumstances we find ourselves in.
It's sensible to get regular check ups including blood tests or seek help with confidential counselling to keep well.
Enjoy the company & chats during his stay.
