    We really aren't running that much behind Italy now.

    Yes we really are, and we are diverging faster and faster.

    Worth remembering coronavirus arrived in the UK and in Italy on the very same day.
    I said it had slipped by two days since Sunday compared to Italy(which could easily be 1 and a half). At best that is diverging. That is not diverging faster and faster.
    Yes it is, its diverging faster and faster because of the exponential growth of the divergence.

    Today our cases grew by 130 vs 211 if we were tracking Italy but weeks behind, a divergence of 81.

    Diverging by 81 now is much faster than we'd diverged in the past in a single day.
    Surely if we are on different exponential paths the absolute difference is likely to increase every day?
    It's never going to be a smooth curve is it? It (the rate of increase) is bound to fluctuate.
    There will certainly be noise but the point of exponential growth is that the differences multiply much faster than linear growth. There have been some suggestions, from @AndreaParma_82 I think, that Italy's growth is now linear rather than exponential which would be a start.
    Something like a Gaussian Process is what is required here, as it will provide a fit to the data including the levels of uncertainty.
    The total number of counts for epidemics will usually follow a cumulative Gaussian curve or a logistic/sigmoid curve. The difference between the two is not worth discussing here.

    This means that the number of new cases will be like a Gaussian bell curve. The new cases (counts) will be much more variable around the idealised curve than for the cumulative counts.

    The problem is we are at the start of the curve and so fitting a Gaussian curve to the new cases or a logistic curve to the total cases and extrapolating into the future has exactly the same problems as Henrietta's models from last week.
    A Gaussian Process doesn't (have to) fit a gaussian curve to the data...

    From Guardian...

    The majority of coronavirus infections may be spread by people who have recently caught the virus and have not yet begun to show symptoms, scientists have found.

    An analysis of infections in Singapore and Tianjin in China revealed that two-thirds and three-quarters of people respectively appear to have caught it from others who were incubating the virus but still symptom-free.

    The finding has dismayed infectious disease researchers as it means that isolating people once they start to feel ill will be far less effective at slowing the pandemic than had been hoped.

    According to the Times before even a cough or high temperature the very first symptom is fatigue, so self isolating people who just feel tired may become necessary

    If the season ends surely Liverpool have won it. Be farcical not to recognise that.

    The PL is won by the team that has most points after playing the other 19 teams home and away. Those are the rules. They can't be bent for Liverpool's convenience. Let the candlelit vigil begin.
    At least TSE will be rightly able to claim he called first it as a possibility.

    South Korea and the UK are being held up by medical critics of the Trump Administration as the way it should have been done here.

    The first of those two is correct.
    Do you apply the same level of contempt to other Govt responses in Europe as you do to the UK?
    Yes.

    I'm just finding it hard to believe that eastern Asian countries seem have worked out how to keep the spread of this thing under control and their economies working at the same time, without coercion, much of it with simple, common-sense leadership, and the US and Europe have completed ignored what they've been doing for weeks, followed inevitably by huge, disruptive lock-downs when the numbers get to where the numbers were always projected to get to.

    "Please consider cancelling events and large gatherings unless they are essential. Please work from home if practical". Why is this hard?

    So dumb. So, so dumb.
    Something that puzzles me about the UK response is that it's pretty obvious (and there's modelling studies to back this up) that contact tracing is a more effective way to control an outbreak if the number of transmissions caused by each case is nice and low. Contact tracing is quite resource-intensive and can be overwhelmed if community transmission is high. To give it the best chance of working, you want to reduce transmission. And we have ways of doing that. So why was no package of transmission-reduction measures (e.g. at least some of the low-cost forms of social distancing) incorporated into the Contain stage of the response, to give it the best chance of working? Only introducing them at the point where you've de-emphasised contact-tracing as part of your response seems to miss out on the potential synergy of the two approaches.

    There must be reasons behind this decision - it wasn't a call made by idiots - and I'm genuinely curious what it was.
    Comment of the night above, cruelly cut off at the end of thread.

    Even as I try to get across that what we already know gives an upper bound well below much of the catastrophising, the holding off on ready options to make the Contain phase easier confuses me and I wish they were implementing social distancing measures faster.
    I expect the answer to MBE's question is that the social distancing and the rest is seen as a strategy with a time-limited utility - i.e. after a while people will get fed up with it - and they didn't want to "waste" it during the contain phase when it will be critical during the "delay" phase to avoid the NHS becoming overwhelmed.
    If I was to put money on it, I'd rate that as most likely. Having said that, is there really not a single transmission reduction measure, however mildly beneficial its effects might have been, that's relatively low-cost and is not time-limited? I understand that people's willingness to comply with things may degrade over time and isn't likely to be as strong here as in certain Asian countries, but HMG does have some key advantages: it can ban stuff and it can render stuff uninsurable. It seems they concluded there were no worthwhile options. Not saying they were wrong - I'm in no position to know - but I still find it odd, bearing in mind it's well-established that contact-tracing is more effective for containment if you can reduce transmission and you'd want to give that a decent shot.

    All this argument of on the curve not on the curve is meaningless for pan national figures because looking at Italy and Spain it was only when a hot spot developed did it start to take off. Watch London and other possible hotspots to see how things are progressing. Yes Madrid is dire with mass closures but as yet we on the coast are seeing sensible actions closing large scale events, schools remain open but universities are quick to shut down when a number of cases appear. Just looking for a sensible approach to Easter parades and travel restrictions out of Madrid to the costas .and continued good weather.

    Donald Trump has said he could not consult with European officials before implementing his travel ban because he had to act quickly.
    He added that the UK was excluded from the ban because they were doing a god job on managing the coronavirus.

    The 2 new deaths, an 89 year old and a lady in 60s, both that had been unwell with significant other health conditions.

    How many people have died in the Coronavirus era of regular flu? How many have died of Coronavirus that wouldn't have died of normal flu?
    How many people are now being saved from death by normal flu by additional social distancing and hand washing? Might be more than Covid19 deaths at the moment?
    Death toll now up to 10 vs ~10,000 dying from flu in a normal year (confirmed by CMO in a press conference recently since some people have claimed wildly differing figures for that).
    If those 10 would have died from flu anyway, likely as they were elderly and ill, is that a sign we might all be over worrying, and the media attention on Coronavirus is hiding the possibilty that in terms of deaths, there is no change on a normal year if you combine flu deaths and CV deaths?
    The problem that Italy are seeing at the moment is that people are not getting operations and other treatment because there are so many Covid-19 cases. These are people who need to be in hospital, a large proportion of whom will survive, rather than people who can be left to "die peacefully in their sleep".

    I think that is is not "overworrying"
    "die peacefully in their sleep"

    Who are you quoting there?
    That is the epithet you often hear for elderly people when they sleep. The implication from the previous post was that we should not worry about people who die from Covid-19, because the numbers are so small. But that is not the problem. The problem is the hospitalisation of too many people. People who will survive if they are treated in hospital and die an unpleasant death if not.

    On Wednesday 11th March the US announced a 30-day ban on travellers arriving from the Schengen countries which would take effect tomorrow, Friday 13th March.

    According to OAG flight schedules, the ban will passengers arriving on nearly 7,000 flights over the next 4 weeks. If those flights were cancelled due to lack of demand that would remove close to 2 million seats each way from the market.

    Of the 26 Schengen countries in Europe, Germany, France and the Netherlands will be most affected as they make up 57% of all flights between the Schengen Area and the United States.

    The most affected airlines will be Delta Air Lines and United Airlines, which, together are scheduled to fly 31% of all flights between the United States and the Schengen Area in this period. Lufthansa is the most affected European airline, flying 13% of flights between the two areas.

    I've no idea if the current apparent slowdown will continue, though.

    Let's hope tonight's figures from Italy aren't too much at the grim end of expectations.

    He's right, but the problem for the Government is that BoZo is not a credible spokesman.

    He is a habitual liar who has consistently contradicted experts to advance his career.

    When he stand at the despatch box and says "we are following the experts" it's not credible.

    He tends to be standing next to said expert at the time. This helps, a bit.

    Unless you think our experts are all cowards, or have been bought off somehow?

    We really aren't running that much behind Italy now.

    Yes we really are, and we are diverging faster and faster.

    Worth remembering coronavirus arrived in the UK and in Italy on the very same day.
    I said it had slipped by two days since Sunday compared to Italy(which could easily be 1 and a half). At best that is diverging. That is not diverging faster and faster.
    Yes it is, its diverging faster and faster because of the exponential growth of the divergence.

    Today our cases grew by 130 vs 211 if we were tracking Italy but weeks behind, a divergence of 81.

    Diverging by 81 now is much faster than we'd diverged in the past in a single day.
    Surely if we are on different exponential paths the absolute difference is likely to increase every day?
    It's never going to be a smooth curve is it? It (the rate of increase) is bound to fluctuate.
    There will certainly be noise but the point of exponential growth is that the differences multiply much faster than linear growth. There have been some suggestions, from @AndreaParma_82 I think, that Italy's growth is now linear rather than exponential which would be a start.
    Something like a Gaussian Process is what is required here, as it will provide a fit to the data including the levels of uncertainty.
    The total number of counts for epidemics will usually follow a cumulative Gaussian curve or a logistic/sigmoid curve. The difference between the two is not worth discussing here.

    This means that the number of new cases will be like a Gaussian bell curve. The new cases (counts) will be much more variable around the idealised curve than for the cumulative counts.

    The problem is we are at the start of the curve and so fitting a Gaussian curve to the new cases or a logistic curve to the total cases and extrapolating into the future has exactly the same problems as Henrietta's models from last week.
    A Gaussian Process doesn't (have to) fit a gaussian curve to the data...
    OK Mea Culpa in the sense that I saw you used the word Gaussian 'process' but I had not expected you to be using the word in the probabilistic sense of a "Random Process". Sorry.

    No problem, its a bit of a niche field :-) But it would be the approach I would be using to model the public data, as would give a fit with co-variance and you can built it such that you take in the different countries data with the differing sample rates etc.

    Just fitting exponential or sigmoid curves through stuff isn't the way to do it.

    However, the egg-heads have a load of private data about location, the network effect being presented between cases etc.

    When you consider that, ultimately, the stock markets reflect the global economy you can see why we're in such trouble. The world is hitting the buffers from 500mph and there isn't any further track in sight right now.

    Businesses all over the globe will be going bust. A very very few will profit and a mid-section of sufficiently large companies won't be recovering to last year's profitability for years to come.

    It's an absolute disaster.

    South Korea and the UK are being held up by medical critics of the Trump Administration as the way it should have been done here.

    The first of those two is correct.
    Do you apply the same level of contempt to other Govt responses in Europe as you do to the UK?
    Yes.

    I'm just finding it hard to believe that eastern Asian countries seem have worked out how to keep the spread of this thing under control and their economies working at the same time, without coercion, much of it with simple, common-sense leadership, and the US and Europe have completed ignored what they've been doing for weeks, followed inevitably by huge, disruptive lock-downs when the numbers get to where the numbers were always projected to get to.

    "Please consider cancelling events and large gatherings unless they are essential. Please work from home if practical". Why is this hard?

    So dumb. So, so dumb.
    Something that puzzles me about the UK response is that it's pretty obvious (and there's modelling studies to back this up) that contact tracing is a more effective way to control an outbreak if the number of transmissions caused by each case is nice and low. Contact tracing is quite resource-intensive and can be overwhelmed if community transmission is high. To give it the best chance of working, you want to reduce transmission. And we have ways of doing that. So why was no package of transmission-reduction measures (e.g. at least some of the low-cost forms of social distancing) incorporated into the Contain stage of the response, to give it the best chance of working? Only introducing them at the point where you've de-emphasised contact-tracing as part of your response seems to miss out on the potential synergy of the two approaches.

    There must be reasons behind this decision - it wasn't a call made by idiots - and I'm genuinely curious what it was.
    Comment of the night above, cruelly cut off at the end of thread.

    Even as I try to get across that what we already know gives an upper bound well below much of the catastrophising, the holding off on ready options to make the Contain phase easier confuses me and I wish they were implementing social distancing measures faster.
    I expect the answer to MBE's question is that the social distancing and the rest is seen as a strategy with a time-limited utility - i.e. after a while people will get fed up with it - and they didn't want to "waste" it during the contain phase when it will be critical during the "delay" phase to avoid the NHS becoming overwhelmed.
    If I was to put money on it, I'd rate that as most likely. Having said that, is there really not a single transmission reduction measure, however mildly beneficial its effects might have been, that's relatively low-cost and is not time-limited? I understand that people's willingness to comply with things may degrade over time and isn't likely to be as strong here as in certain Asian countries, but HMG does have some key advantages: it can ban stuff and it can render stuff uninsurable. It seems they concluded there were no worthwhile options. Not saying they were wrong - I'm in no position to know - but I still find it odd, bearing in mind it's well-established that contact-tracing is more effective for containment if you can reduce transmission and you'd want to give that a decent shot.
    This is the playbook the Government is working from https://www.gov.uk/guidance/pandemic-flu

    And annex c of https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/225869/Pandemic_Influenza_LRF_Guidance.pdf covers school closures and why you can't rush them
    It's not exactly their playbook because this isn't pandemic flu, but a lot of the preparedness across government will be based on that document. Children seem to be affected by COVID-19 very differently to flu, so no doubt this will be something they'll be modelling very carefully. (In fact they'd be modelling it carefully even with flu! But a trickier task this time around as children's role in the epidemic remains murky.) I wasn't talking about anything as drastic as school closures, apologies if my post was insufficiently clear. It was the complete absence of even low-impact social-distancing measures during the Contain phase that had caught my curiosity.

    I think Philip's point is that they are getting worse but more slowly than Italy did. If you go for the "ideal time" approach that is clearly important.
    This shows Italy and UK infections on a log scale up to 10 March.

    It appears to me that the exponential growth is slowing down in both countries.

    I would have thought the argument was to be selective. In "hot spot" areas the schools should close now, the SW for example. In other areas the matter can be kept under review at the moment.

    In Coronavirus news, at my sister's daughter's school in Croydon, one of the pupils has tested positive.

    They are not closing the school.

    Should be closed for a deep clean then reopened.
    The risk, I think, is that if one student has it, then another might do as well.

    By reopening it, you introduce a highly probable method for community infection.

    On the other hand, closing the school causes terrible problems for the families with two working parents.

    There are no easy answers.
    My sister in law's sister's kid's school was closed a couple of weeks back as a TA tested positive and the child was isolated (in family home) for two weeks (just back at school now, I think).

    Odd that this one would be different - unless the pupil has not been in school since infection? In that case you can see that merely restricting the contacts could make sense.

    The Eck trial is exploding today - bombshells ahoy.

    Testing, testing:

    For what it's worth:
    USA Tests: 8,554 Positive cases: 1,374 Ratio: 16.1%
    UK Tests: 29,764 Positive cases: 491 Ratio: 1.6%

    The US deaths to recoveries ratio is even more shocking.
    Not as grim as France's (USA 38 dead - 15 recovered; France 48d. - 12r.) But I suggest it's a meaningless figure at the moment due to variable definitions of 'recovered'.

    I just built a model by holding a ruler up to my computer screen against some graphs, and now I am panicking. Please send help.

    First thing to do is disinfect the ruler.

    Must be coordinated. Gives Sturgeon some kudos and distances Boris from the nitty gritty. He doesn't need to acquire a perception of gravitas, has not been his style.

    Only (very big) problem is that is the Sturge speaking for the UK or for North Britain? Leaves us punters confused.

    Dribbling news out bit by bit makes sense at the moment -
    I think we need one single voice. We need an Ian McDonald.

    I think the DCMO was pretty impressive (as indeed I have to say was the Q&A itself) with BoJo.
