I spent Monday evening with a group of friends (bellringing) and on Tuesday, one tested +ve for covid. He naturally told us all but what now? Am I supposed to self-isolate for a week? Or carry on as normal? Something in between?
As it happens work is quiet and I had one boiler fix booked in yesterday so I call the customer to tell them and they said "Not bothered, come anyway please"... and I'm alone moving one of my boats for the next day or two. But the thing is, I now realise I have no idea what the government 'advice' is, given there are no laws on it in force (I think!)
I share the same understanding already stated by a few people here, i.e. there is now no legal requirement whatsoever to isolate after possible exposure, and in fact not even if you subsequently test positive. My understanding is that it's all left down to individual judgement now, at least in England. I haven't followed the regulations in any other nations.
In exercising judgement you might find time index 18:30 to 20:00 of this video (
https://www.youtube.com/watch?v=KLNoY6f6SE0) interesting since it covers one aspect of your situation namely how long after exposure might you test positive on an antigen test if you have caught it. The answer according to the clinician in this video(*) is 2-3 days after exposure which is down from the 6-7 days for the original strain.
(*) The clinician is Dr Daniel Griffen who from previous videos I have seen has access to data from a number of hospitals beyond just his own. Details on his background are here -
https://en.wikipedia.org/wiki/Daniel_O. ... 7d093432da - and this video is one of his TWIV clinical updates mentioned in the Wikipedia article.
Since I've linked that video there was another bit at time index 10:40 through to about 11:50 I found interesting in terms of general chat. Dr Griffin says that he is seeing about 80% of his patients who test positive for Flu are also testing positive for SARS-CoV2. He points out that in clinical settings where once a SARS-CoV2 infection has been identified they don't test any further, in particular for Flu, then you obviously won't pick up a Flu co-infection.
Since the UK has done so much SARS-CoV2 testing I do wonder how testing is handled when a patient presents with something looking like Covid-19. Is a SARS-CoV2 test immediately administered and if positive then no more tests are done? If yes then if Dr Griffin's data is at all representative it casts some doubt in my mind as to whether the narrative that I have heard in some places that Flu was virtually non-existent last year is accurate. Maybe we just didn't see a lot of Flu cases that, due to the infectiousness of Covid-19, were co-infections because we only tested for SARS-CoV2.
Maybe that possibility of undetected co-infections is not an issue in the UK or is somehow factored into the assertions about the lack of Flu. The assertions that I have heard have been from seemingly (to me) very experienced virologists and epidemiologists and I certainly am not arrogant enough to think I know more than they do, I would just be curious as to whether that overly-focussed testing is not an issue in the UK for some reason, or if it has somehow been accounted for when claiming a lack of Flu, or if other factors are at play. Food for thought at least that does leave me with some nagging doubts.
