Thanks as usual, Andrew. I agree that we know too little. Being cautious is vital, especially for many of us who are over 70 with "circumstances". I would have appreciated that, under pre Covid, people who were contagious with anything not stay in my home. Now that we have a pandemic that is evolving, mutating, and ubiquitous, it would be decent for any of us to scrupulously avoid passing on this thing to anyone else.
How can we best support this? We cannot, ask, require, or certify as to anyone's health, so we remain vulnerable in the least attractive manner. I trust my guests, however right now with so little information and so few facts, trusting each other on Covid is not such a good idea. As you know already, I am aware that we cannot buy good health. No money is enough to make that gamble. We are therefore prevented from hosting, in good health, while this pandemic is ongoing. Such a pity, we miss it on so many levels!
