Track and trace

I assume people who have coronavirus will be asked by contact tracers for details of who they have been in close contact with. Possibly they will try to identify contacts that lasted for over 15 minutes. Those asked won't remember everybody, never mind the precise number of minutes they were in close contact with each person. Nor is the app likely to change that. From the link I posted earlier:

"Part 2: if you are contacted by the NHS test and trace service because you have been in close contact with someone who has tested positive for coronavirus

1. alert: you will be alerted by the NHS test and trace service if you have been in close contact with someone who has tested positive for coronavirus. The alert will usually come by text, email or phone call. You should then log on to the NHS test and trace website, which is normally the easiest way for you and the service to communicate with each other – but, if not, a trained call handler will talk you through what you must do. Under-18s will get a phone call and a parent or guardian will be asked to give permission for the call to continue

2. isolate: you will be told to begin self-isolation for 14 days from your last contact with the person who has tested positive. It’s really important to do this even if you don’t feel unwell because, if you have been infected, you could become infectious to others at any point up to 14 days. Your household doesn’t need to self-isolate with you, if you do not have symptoms, but they must take extra care to follow the guidance on social distancing and handwashing and avoid contact with you at home

3. test if needed: if you develop symptoms of coronavirus, other members of your household must self-isolate immediately at home for 14 days and you must book a test at www.nhs.uk/coronavirus or call 119 if you have no internet access. If your test is positive, you must continue to stay at home for at least 7 days and we will get in touch to ask about your contacts since they must self-isolate. If your test is negative, you must still complete your 14-day self-isolation period because the virus may not be detectable yet - this is crucial to avoid unknowingly spreading the virus."

Thanks for that, it definitely explains it clearly.
What I was struggling to comprehend, but which is stated in black and white in your post, is that you isolate for 7 days if positive but 14 if negative.
Before reading your link I thought people were incorrect in this assertion, as it sounds so counter intuitive to me.
One thing I would say, in relation to other posts and not yours, is that a second wave is a possibility and not an inevitability. If the public keep to the new normal of social distancing we can be optimistic that it won’t necessarily happen, and personally I’m not seeing people ignoring the advice, although I’m constantly hearing that social distancing has ended. The drop in deaths says to me that the measures have worked so far and I don’t see why this won’t continue.

I think the point is that you can have mild or no symptoms for 7 days and then take a turn for the worse (like Boris). You either end up in hospital or are most likely to be clear 7 days after you start symptoms.

The average time to catch it is around 5 days, but they think that 99% of people who were going to catch it would do so by day 14. So it is safer to say people should stay isolated for 14 days. If you do catch it then you start the clock of 7 days from when you first had symptoms, as after that time you are unlikely to be infectious.

People might mind never being able to go to a football match again, though!

Thanks for this. When you say an average 5 days to catch it, I’m not sure what you mean. If my wife had it, I probably won’t catch it today even though we’re in the same house/bed, it takes a while to transmit? It seems as though you need to be subjected to a certain dose rather than just one or two of the micro droplets that we hear about. I suppose that’s why we are sadly losing NHS staff but not supermarket workers in any great numbers, even though these people are doing a great job and being in the same building as hundreds of the public each day.

An average of 5 days for you to show symptoms ie 5 days from when you were in touch with whoever you caught it from.

Oh I see, you can catch it quickly but the symptoms are mild or non existent for the first few days. 👍
It’ll be interesting to see how many people are asked to self isolate once this system is properly up and running. The smart phone app, if it works as stated, seems a much better system to me but we’ll see.

You need to understand the difference between catching a virus and the incubation period of a virus. The moment you come into contact with enough virus you can catch it but with some viruses, Covid being an example, it can take anything up to 14 days for the virus to incubate and grow enough in your body for you to start showing symptoms. With other viruses, such as cold and flu it can only be a matter of hours before the effects become prevalent, hence why CV19 is so dangerous.
