Most recent T&T data now out, covers 4th - 10th Feb

LFD use continues to rise but more slowly than last week and T&T performance remains consistent.

And as ever we don't know about who isn't tested and who struggles to isolate.

The number of people being tested each week remains high at around 3m, but this is due to increasing use of rapid lateral flow devices as PCR test use falls.
The number of LFDs used has increased five-fold since the start of Jan, and 35% in the past two weeks (although noticeable slowdown this most recent week).

By contrast, PCR test use for people with symptoms fallen week on week for the past month (PHE positivity data due later).
LFDs are generally used by people without symptoms to find cases that might otherwise unknowingly transmit disease. Current use focuses in places like schools, health and care, some workplaces, and community testing sites run by local gov for people who can't work from home.
There's definite variation in their use across the country (but note chart isn't pop adjusted) and as mentioned last week, will need to keep close eye on how use varies, particularly among more vulnerable and deprived groups.

Need to mitigate any unintended harm, esp around jobs
The number of people testing positive is falling as we know, meaning around 30% fewer transferred to T&T this week compared with last week.

That's 106k cases.
Test turnaround time is consistently as fast as it's ever been, with 85% of in person PCR test results received within 24 hours.
Of the 106k cases transferred, 92k were reached (87% of those handled), and 68k (74%) gave details of contacts.

Both these percentages are similar to previous weeks.
There were 191,242 contacts identified, or 2.1 contacts per case (although for the 5,344 cases handled by PHE health protection teams, the median number of contacts per case was 25 - largely due to management of variants of concern).
94% of contacts were reached.

Worth noting that given lockdown, 87% of identified contacts were household contacts of which 97% were reached, this compares with 71% of non-household contacts.

These percentages reached have all been similar since start of Dec.
And there are ongoing differences by local authority which have highlighted before and still need more detailed explanation.
The national data also doesn't report the impact of local contact tracing teams on overall T&T performance.

Local teams generally pick up cases that can't be reached by the national team within 24hrs and their role may become ever more important as case numbers fall.
Finally, end-to-end time is consistently as good as it's ever been.

Room for improvement but definitely not getting worse.
And as with every week, these data don’t tell us about people who don’t get tested despite symptoms and who don't always isolate.
Everyone needs to be confident they will have the support needed if testing positive, and that their job – however insecure – will not be put at risk.
We'll update our @HealthFdn T&T performance tracker with @cfraserepi later this afternoon with these data.

Typically excellent piece from @dsquareddigest The exponential insight is especially neat. Think of it a little like fishing...today you can’t export oysters to the EU (because you simply aren’t allowed to), tomorrow you don’t have a fish exporting business (to the EU).


The extremely small minority of people who known anything about this who think that Brexit will be good for the City make a number of arguments which I shall address in turn...

1. They need us more than we need them. This is a variant of the German carmakers argument. And we know how that went...Business will follow the profit opportunity and if that has moved then so will the business...

And what do we mean by us / we. We’re not talking about massed ranks of Euro investing / trading etc blue blooded British institutions.

Au contraire. We’re talking about the London based subs of US, Asian and indeed European capital markets players...As soon as they think the profit opportunity has moved then so will they...it’s a market innit...

THREAD: 12 Things Everyone Should Know About IQ

1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE


2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less.
https://t.co/UqtS1lpw3n


3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)

(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)


4. IQ predicts many important real world outcomes.

For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3


5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)

Gobind Singh followed Bahadur Shah to Deccan to fight for him.


In Zafarnama, Guru Gobind Singh states that the reason he was in conflict with the Hill Rajas was that while they were worshiping idols, while he was an idol-breaker.

And idiot Hindus place him along Maharana, Prithviraj and Shivaji as saviours of Dharma.
