@bigTillyMint, I feel your pain. He is still testing negative, and I have not had confirmation that his friend had a positive PCR test. I assume so, but you never know. As he is still in uni city (not London) there is no immediate risk to us, and if he is still negative by the time he is due to come home I won't be too freaked out. Tbh I am far from convinced that Omicron poses a real health risk; I have seen nothing thus far that worries me. Yes, it is more transmissable, but less likely to attack the lungs, and if after 3 vaccines I am still expected to lock myself in a cupboard until the virus burns itself out, then what on earth is the point? Sorry for the rant. His friend may have had Delta anyway; this is still equally possible, and so far there are no reports of anyone else catching it.
@Decorhate, thanks for the advice. As it is not govt policy there is nothing to stop him working. Obviously he wouldn't if he knew himself to be infected. He can only do paid work there, not here, so won't come back until after his last shift. If he tests positive he will have to stay there alone, but I would probably drive over and leave food and presents on the doorstep. He has been lucky not to have caught the virus a second time, after doing so on his return to uni in 2020, despite having been in close contact with others that have. It's just a waiting game.
