Dr Susan Hopkins from Public Health England, and Dr Maria Van Kerkhove, Covid-19 technical lead at the World Health Organisation were on Marr this morning, and unless I misheard they were aware of and researching this new strain from Kent, UK in September and October, during this time understanding how the mutations affected transmissibility of the virus.

This particular variant was identified from whole genome sequencing in the middle of October, from a sample taken in September. It continued to spread and in December, early December, while we were trying to understand why Kent and Medway continued to increase despite the national restrictions, we found a cluster that was growing very fast and that had spread not just from the South of England, into London, and parts of Essex. We still did not understand what the difference in transmissibility was and this week, the modellers and academics we work with in Imperial and other partners, demonstrated that it was indeed more transmissible than other variants circulating. We alerted the government to this fact on Friday and immediately government started to take action.
Flight bans, travel bans, London locked down all because this strain is more contagious?
Feels like some other shit is going on that they're not telling us about
Probably not, a plane has to return and commercially it makes sense to fly a plane on the proviso that it earns money on the way home. I can't see the bans changing for at least a month.

You make it sound like a small thing.
Apparently the french ban is for all flux, there is no way it last a month. The UK needs supplies.
Watching the news now...and they're suggesting that it could be 71% more contagious, and it could increase the R rate by up 0.9

I hope you are right, I hope it's much less than 75%.They absolutely do not have the evidence to suggest that with any conviction. It's like their modelling that suggested 2m people could be hospitalised. Too many assumptions built into too limited a model to make these statements without huge caveats. You can talk to epidemiologists that way because they will know how to contextualise the numbers and their reliability but I can't see how this is good public health messaging, unless its only goal is to cause mass fear. The tests next week could very easily provide a completely different pair of numbers. The direction is reasonable to communicate but the specificity is miscommunicated.
I hope you are right, I hope it's much less than 75%.
Because with 75% or 71% more infections I don't see how at anyone point we'd have had the virus under control
Have the Nightingale Hospitals been opened yet? Not heard a thing about them.
People don’t need to be getting coffee at the local store.
It's childish to absolve these people in the picture of any responsibility. This is 100% hubris & selfishness by the people. Don’t try to blame their idiocy on the government. They’d do it even if christmas wasn’t rightly cancelled.
Eurotunnel said trains would still be running services from France to the UK that were vital for medical supplies and other essential goods. A spokesman said: “Eurotunnel recognises the importance of combatting the spread of coronavirus and we will be implementing the measures as we have done throughout the pandemic.”Transport to and from the UK halted at midnight tonight, does that include the vaccine's?
They're still open.
I agree with you that communication has been rubbish. I don't agree with you that rules are inconsistent and there are reasons that explain why similar situations are handled differently, based on different sets of societal priorities. But let's accept your position on that too.
We now know this is a dangerous time. We also know the vaccine is a legitimate exit strategy. Let's say we stop paying attention to government rules and instead make judgments bases purely on what is the best way to handle this pandemic as a society. If you choose to see your friends, your family, etc. you are taking a risk that you will spread the virus. Every one of those interactions counts, not just the parties. The motivations can provide individual justification but that doesn't change the epidemiological outcome. The self isolation is only plausible in very specific circumstances for a few people. People gotta eat.
If people weigh up their own individual risk of catching and passing on the virus, don't you think they'll end up making decisions that are an acceptable level of risk for them as individuals, but an unacceptable risk for society? Is there any reason to believe that if people were left to rely on their own judgment, they would be able to manage things in a way that prevent hospital capacity going over 90%?
If not, then choosing not to judge those decisions therefore encourages individuals to take actions that cause more societal harm. I don't see any way around that.
Are they giving out estimates of a 0.4 to 0.9 increase?The number 0.9 to me didn't sound right because I'm sure the PM said 0.4 yesterday. I can see where the breakdown in communication is. This comes from Nervtag's meeting minutes that were framed for a particular audience, and the media are reporting on it very, very badly if the takeaway people are getting is it will increase things by 0.9.
Their esimates range from 0.4 to 0.9 and it's based on correlation studies which "suggest" those numbers. The media are bad at science reporting in general but I think this is particularly bad. These correlation studies and models are very limited, and it's at a very early stage. We conclusively do not know what impact it will have on the r, they just had to provide their best estimate so the PM could make a call pre-Christmas.
Their key conclusion is that they have "moderate" confidence it demonstrates a substantial increase. They by definition have significantly lower confidence in the precise estimates, and presumably high confidence that it demonstrates some kind of increase, but it may not be significant.
For some reason we're focusing exclusively on the grave news. There are plenty of other details that paint a more complex picture. For example, they know someone from the UK with that virus strain brought it to Australia. Presumably they used a form of transport that exposed them to other people on the journey, and after the journey. No-one else got infected by it. It isn't some kind of super-strain.
If it increased the r rate by 0.4 then some of the measures imposed during the lockdown were estimated to have reduced the r rate by that amount too. No catastrophes. Maybe if you close schools temporarily you achieve a kind of equilibrium.
With opinions such as this being so prevalent we hav’nt got a chance and the U.K. is well and truly fecked. Talk about ‘it’s not my responsibility’. Its at times like this that it crosses my mind that a ‘police state’ might not be a bad idea.
Yeah this is their translation of the R number. It is more easily interpretable the 71% more transmissible estimate.Are they giving out estimates of a 0.4 to 0.9 increase?
I assumed you just, you know, increase the R number by 75%? It's (allegedly) 75% more contagious? The R Number is effectively a measure of the viruses contagiousness over it's lifespan? You can't just add a standard number to it, that's ridiculous.
Regardless I feel really really shit right now sitting in the middle of Tier 4 Lockdown. Christmas is cancelled. Everyone I know is devastated and feeling like they've been punched in the gut. Friends jobs are fecked again, but also schools closing is going to be a killer. If the 70% or 75% more infectiousness is correct then I don't see how that even the most extreme measures we took at the height of lockdown would have been enough to get R below 1.0
Like you say, maybe the media are exaggerating. If the one thing the media are known to do, it's to take a figure and run with it without context.
But god.
NERVTAG said:Studies of correlation between R-values and detection of the variant: which suggest an absolute increase in the R-value of between 0.39 to 0.93.
...
In summary, NERVTAG has moderate confidence that VUI-202012/01 demonstrates a substantial increase in transmissibility compared to other variants.
Dr McBride urged people to behave as they did in March, when the restrictions and behaviour saw the R number fall from almost 3, down to 0.7 by July.
What a shit few days. I expect panic buying tomorrow due to the news around ports.
Case rate, potentially not, but you shouldn't be solely looking at cases in isolation. The motivation for the restrictions is all related to ICU and hospital capacity, the stricter the measure should give an indication as to the severity of the capacity issues. Wales had last week one day where they had 10 free ICU beds across the whole country. So they can balance an increase of case rate, as long as the hospital's capacity is in a healthy status.
The transmission pattern for the tier 4 areas, has grown at an extremely sharp rate over the past week. You can't see the data in one or two days due to the fact that the current turn around time on tests is about 3.1 days and increasing daily. So in reality the decisions being made on Friday/Saturday is based off tests that were taken on Tuesday at the latest.
The thought had crossed my mindShouldn't be much really, most retailers have stockpiled for Brexit. Exports will be worst affected.
At least we get an early insight into what Brexit looks like on January 1st.
Yes but it's not a simple as saying "we dropped the R-Value from 3.7 to 0.7 previously and we can do it again" well no, we went from a completely open economy to a completely shut economy. We do not have a completely open economy now. If the R-value in March-April was 0.6 then and it's 70% more infectious, and we can just do 0.6*1.7 which, you know, maybe I am wrong about, then that is 1.0 back in March-April.Yeah this is their translation of the R number. It is more easily interpretable the 71% more transmissible estimate.
We have achieved much bigger drops in the R number so you shouldn't panic. E.g. here is the reference point from NI:
It's from this article. People are getting arried away because of the way this being communicated and contextualised, IMO.
Hi guys,
Reading reports here in NA about the bew coronavirus strain in UK.
Will the Covid vaccine be affective against this new strain?
Yes but it's not a simple as saying "we dropped the R-Value from 3.7 to 0.7 previously and we can do it again" well no, we went from a completely open economy to a completely shut economy. We do not have a completely open economy now. If the R-value in March-April was 0.6 then and it's 70% more infectious, and we can just do 0.6*1.7 which, you know, maybe I am wrong about, then that is 1.0 back in March-April.
feck. What else can you close?
Also, It's winter. March-April was an (actually very nice) Spring-Summer.
Also, March-April wasn't good. My kids weren't at school. Their school was shocking at providing home learning. The government spent large percentage points of GDP to keep going and the economy subtracted by large percentage points of GDP.
Ergh
It looks like this virus isn't very transmissible fortunately.
According to the European CDC the chance of the virus spreading to Europe is very small.
We consider it a small chance that the virus will appear here since there is no direct traffic to Wuhan from here.
There is a backlog in today's reporting, 8.4k cases dropped in that weren't included in Wednesday's number.
Alright I'll leave you to your despair but I'll just say that isn't the right way to use the 71% transmissibility estimate, even if it were accurate
That's just ridiculous. Wear masks, dont mix, keep distance. It's not that fkin hard.The infection rate here is soaring but has been very low compared to other areas for the whole pandemic until now. It's a bit daft not to attribute some of the speed of the infection rate to the fact a lot more people here simply wont have had it at all yet.
Regardless, surely the overall transmission patterns would give a fairly accurate idea that there was a problem before this fecking Friday. For example, I knew there was a problem before then, because I looked at the publicly available data and saw that there very obviously was. We've crept up from 40 cases per 100,000 to nearly 500 per 100,000 in under 2 months. It hasn't just suddenly happened this week, no matter what it's attributed to.
We need rules for something like this because it's a crisis, and most people lack common sense at the best of times, never mind when they are in survival or reactionary mode. Give people guidance that helps them get through a crisis and they will generally stick to it rather than take risks.Give them guidance that keeps changing, often contradicts itselfm and at times obviously makes no sense, and people will end up all over the place or making their own decisions.
It's like being in a burning building and having to choose whether you let someone guide you out. If they're dressed as a firefighter and appear to be leading you to where they think the exit is, then you're probably going to follow them. If they're dressed as a circus clown and keep changing their mind about which way to go, and occasionally try to make you walk through things that are on fire, you're probably going to start thinking about finding your own way out, or at the very least start getting very angry at them when you notice your arm is burning.
At some point we have to look past Boris and address the elephant in the room, that being a significant number of the populace put their full trust into him not once (Brexit) but twice (the last election).What the feck are you on about? Where have I said anything is not my responsibility?
I simply think it is quite important during a world pandemic that the people in charge aren't complete idiots who have no regard for anyone else's wellbeing, and I don't think that's what we have unfortunately .
In fact at this point if you think Boris is in any way competent and not a dangerous person to have in charge of managing a pandemic, then I think you have to be somewhat mad. They guy came on national television in March and TOLD you to go visit a covid ward and shake hands with everyone there.
Also, anyone know exactly why this variant is more virulent and what adaptations covid19 has made to itself to become much more contagious?Can someone tell me how the rest of the world is reacting to this new virus strain in the South East?
Obviously, I can see that countries are closing their borders - but - what's the general consensus.
Is that strain just here (SE UK) at the moment? Or has it already spread? Did it start here? Is the 75% more infectious considered correct?
