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.

More from Government

The Government is making the same mistakes as it did in the first wave. Except with knowledge.

A thread.


The Government's strategy at the beginning of the pandemic was to 'cocoon' the vulnerable (e.g. those in care homes). This was a 'herd immunity' strategy. This interview is from


This strategy failed. It is impossible to 'cocoon' the vulnerable, as Covid is passed from younger people to older, more vulnerable people.

We can see this playing out through heatmaps. e.g. these heatmaps from the second


The Government then decided to change its strategy to 'preventing a second wave that overwhelms the NHS'. This was announced on 8 June in Parliament.

This is not the same as 'preventing a second wave'.

The Academy of Medical Scientists published a report on 14 July 'Preparing for a Challenging Winter' commissioned by the Chief Scientific Adviser that set out what needed to be done in order to prevent a catastrophe over the winter
Abbott is pushing a lie to protect incompetence. There is no Federal oversight of the Texas Grid, ergo fewer regulations (sound familiar) - so point one: state legislature needs reform. 2/


2. Point 2: there were clear signs the grid would get overloaded under extreme cold conditions. Why? Due to a vacuum of regulations mandating winterization of turbines and power generators. This from sources, in Texas!

3. Point 3: Of the power shortfall that hit Texas, over 80% was due to problems at coal and gas fired plants. Power generators were just not winterized. Decisions to do so have been ignored since the 1990s.

4. Point 4: these are winterized wind turbines in Denmark. The ocean is frozen. The turbines are generating.


5. #Texas| the main issue is: catastrophic governance at the State level (no Federal oversight of the Texas grid) failing to allocate funding to winterise the Natural Gas, Coal and Wind Turbine elements that contribute to the grid. (~ 80/20
