    Some articles for the doubters. Underground trains are continually mechanically ventilated by fan, as well as opening doors every couple of minutes.

    https://foi.tfl.gov.uk/FOI-0219-2122/LU%20train%20ventilation%20rates.pdf

    That’s 9l/s per passenger at full crush load.

    Let's say a pub has a floor area of 100m2 and a 3m ceiling height and is as full as a tube train crush load at 7people /m2. That's 700 people. How many pubs do you know that have ventilation system that can get 6.3m3 of air per second in and out? In other words completely replace all the air in the pub every 47 seconds. That is quite a drafty pub or restaurant or office.

    To be clear, I'm sure someone has caught Covid while on the tube, I just don't think it's as risky as suggested.

    Flights are annoyingly expensive in the post covid world.

    Quarantine is also annoying. I'm losing my sanity.

    Ah. 😬. Not in HK, I hope.
    No. Stuck at home. A place I'm quite familar with after the last two years.
    A colleague went back to see her family in HK over Christmas. 17 days in a single hotel room; not allowed out of the room under any circumstances. And that's if you test negative on arrival.
    Fortunately, my flat is larger than the average HK hotel room and I've finally tested negative, so should out tomorrow meaning that I will have only been inside for 12 days.

    In short, yes. I didn't think going out when I had a covid infected house was a good idea. In any case, I had sick kids to look after.

    Also, note it it is 10 full days after you test positive/ have symptoms, so easily 11.

    Yeah fair enough. I'm on day 5 today and still testing positive. I believe 6 is the minimum now (start testing on day 5 and you can go out after 2 negative tests).

    Yes, the daily hope crushed by highly effective lateral flow tests.

    Our latest batch of lateral flow tests are the throat ones again. Disappointing.

    I didn't know there was a difference in them. I have three types here and assumed test was the same in each of them.

    I’m pretty sure each manufacturer use their own validated antibodies in the cassette.

    Where do you stick the third sort ( I’ve had throat & nose, and nose only)?
    I would guess that throat (near tonsils) would be a bigger sample so add sensitivity, and anything in your nose will end up there too.

    This is interesting: https://coronavirus.data.gov.uk/details/whats-new/record/af008739-ffa3-47b8-8efc-ef109f2cfbdd

    Going to be a step change, so we'll see how by much the cases number has been under reported.

    Yeah they all seem to have different timings, number of swabs, number of drops, even within the nose only type.

    I quite liked how it represented the number of people in the UK who had been infected at some point.

    I haven't noticed any difference in the results between the different types of test. They both seem to show the same level of infection (as measured by speed and strength of line).

    I've also learnt that you will test positive with a minor swab inside of your nose. Twisting it 10 times deep inside is unnecessary.

    France had a relatively quiet day yesterday, but today they’ve broken the half million case barrier.

    I've found it interesting how specific they are about waiting 15 minutes for a result, when actually mine seems to show positive within about 20 seconds.

    Yes it does to begin with but the day before you get a negative, you will probably have a faint line show after more like 5 mins.

    If they're catching up with us on total case numbers but doing it with Omicron not Delta, that's better isn't it?

    Edit: they overtook us a week ago.

    Omicron case numbers are irrelevant now unless you're not vaccinated, over 65, diabetic or have other chronic health conditions.

    More numbers is just getting it over quicker.

    I am still concerned the vulnerable can no longer be protected. Doesnt appear to be a solution.

    Not sure about that for the vigilant.
    Nearly 2 years in and all clear, as are all elderly family members.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    A harder job with omicron, I fear. It'll find the cracks sooner or later.

    Depends on how long acquired immunity lasts. 3 million had it last week. Can't take long at these levels for it to basically burn out.

    I agree.

    My mum thought she could avoid it. 100% scared of going out, leaving parcels for two days, disinfecting deliveries, right up until she caught it visiting my 97 year old grandma.
    Then again, 70, triple jabbed and having had a heart attack isnt particularly high risk. She now wonders why she spent two years frightened of leaving the house.

    She presumably has only been triple jabbed for less than 6 months.

    I think it was almost 3 months so perfect timing if there is such a thing.

    If you happen to have kids 12-15 years old and are thinking of travelling to France, this might be of interest .......

    My kids both had their 2nd jabs on Saturday (22nd Jan). On Sunday, via the NHS website I requested Covid certificates for each of them - they arrived today. These contain a QR code for each jab they’ve received, which can be scanned by the Pass Sanitaire app and provide the Covid pass they need to be able to enter restaurants, cafes, use ski lifts, public transport etc etc etc......

    Note - There is an alternative way to get the QR codes. As their parent, I can request Proxy Access to their records on the NHS app (you need to request this through the child’s GP), and this also provides access to the QR codes.
