It does seem a long time when this virus is supposed to be so virulent. They have been consistent with it though so they must be comfortable with that time frame.

15 mins will have been worked out by science as to what's the time where the risk starts to get too much
If it was 10, 5 or 2 mins the country would be all isolating

Its a dosage assessment. The virus is dispersed on droplets and one breath in is unlikely to take in a large dose even if a Covid shedder has just breathed out nearby, but over the course of a prolonged period nearby, you will take in more virus. 15 minutes is an assessment how long it is likely to take to get a large enough dose. This is part of the same reason outside is better than inside, there is much more dispersal outside, very unlikely to pick up repeat doses of Covid (UV is also a factor).

Now I do "get" the 15 minute thinking. ?
Forums are genuinely useful at times aren't they? Your question got an interesting response, I got one yesterday about the app. In between the daftness ..............

I had to look up BLE Proximity Profile, some cunning stuff. Found this interesting if you like ur inner geek ( https://www.diva-portal.org/smash/get/diva2:859549/FULLTEXT01.pdf )
Beyond the BLE sensing capabilty, I won’t be surprised if it uses some form of software triangulation that combines wifi, cellular, gps etc to pinpoint the phone. Remember we are pushing tech into new use cases here. Previously these would be restricted to indoors/outdoors or trusted/untrusted devices, now we are using it in all conditions.
While digital signals dont attenuate like analog signals - it will need to compensate for someone carrying the phone deep in her handbag v someone carrying in shirt pockets. All that but of tech will come from Apple & Google via an API.
The NHS app will simply ingest the data and then use some clever algorithms and analytics to make it specific to the U.K. it will also add the extra features like checkin, test results and local news. That is where the money goes - not really on a cute app

Just had a call from my daughter, she's showing symptoms now and is off to get a test shortly. She sounded in good spirits and hopefully she'll get through it without too many dramas ?

This University residential situation seems out of control now. Surely the students would be better at home.

Possibly, on the flip side my daughter is in a sort of controlled environment so all those at risk of infection are isolating in the same place, call it one massive bubble if you will. I'd rather her be there than potentially spreading it all over the place to be honest.

Student halls sounds like a perfect place to spread it and gain immunity to me. If anyone has known underlying conditions, get them out and let the rest of the kids party 24/7 for 2 weeks and get it out of the way.

She actually said she'd rather catch it now so she can get on with her life than catch it X months down the line.

But that's assuming you can't be re-infected, which as far as I know is possible. But then again I do not blame her with that attitude as I am sure many others are feeling the same.

That's the million dollar question isn't it. If you can get re-infected then theoretically we could be in some form of lockdown for the rest of our lives as it will never go away. Weird times indeed.

Very few cases so far, some wrongly reported(ie. false positives) and some of the others had no symptoms, so the immune system was actually doing what it should do, fighting off the infection. There will always be the outliners as such as well, so people who do actually catch it more than once....
If antibodies disappear, which could be the case, then it is likely T cells will be with you for years. So for example with SARs, antibodies reduce over 2-3 years but the T cells have been found to still be there something like 17 years later....The bummer is that as you age ,T cells become less!
So far basically nothing to worry about tbh and long may it be the case.

With what has come to pass I'm wondering if, back in May, students planning to go to Uni had really known or been fully informed about the risk associated with the virus in a Uni/halls context, and the likelihood that the key risk mitigation that is Test, Track and Trace would not fully up and running efficiently by September, that these students would have made the same decision to go to Uni. I suspect that whilst many would still have accepted the risks, many would not have done so. And so I can understand that, at least some, students may well be feeling just a little bit miffed - if not duped - and angry about the situation in which they find themselves. And who would blame them. The situation in respect of Uni halls and their course learning is both absurd and outrageous - verging on scandalous.

I was under the impression that some people in the far east had been re-infected. And this was from a BBC podcast with their health correspondent and not some crackpot tin foil hat web site. But the number of cases was extremely small so could have just been a freak incident. Suppose as we get to know more about this then we'll get a definitive answer.

The are loads of people working in Universities that are not students and in the higher age groups ...

Indeed there are - though I am not sure how that fact would impact the decision that a student planning to go to Uni would have made back in May.

Hope she is fine. She is young and very very likely to have a benign course. May feel a bit hungover and achy, but she's a student so that feeling may be familiar to her already.

Re-infection is a big area for discussion right now. I think the general feeling is that it is possible, especially with a mutated (different) strain, but that if it was a common problem, we would have seen a lot more by now.
There is good evidence that people who get infection (or vaccination) get an antibody response, and that response is protective. However, antibodies wane with time, and the immune system then relies on T-cell activation to trigger immune responses. Again, there is pretty good evidence that there are people around who have no antibodies but who have T-cells which react to Covid, so in addition to the slightly less than 10% of people who have antibodies, there may be a similar number who have T-cell activation which offers effective immunity.
But immune systems are quite individual with lots of genetic quirks. all kinds of weird stuff can happen. There are people who do not mount an immune response to some antigens, and people who mount excessive immune responses. So anecdotal reports of some bloke in China or Italy who got infected twice should not scare the horses. You never really know how reliable the reports are or whether there are other factors which explain it. Even if there aren't, still rather rare so far.
