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

Because it's Christmas eve and there's not much else to do whilst sitting in a dark room waiting for small people to go to bed, here's a quick look at today's T&T data.

Covers 10-16th Dec.

Test times much worse, contact tracing continues to

Any graphs this wk are from PHE report. T&T are just providing data update.

Number of people tested up 12% to 1.99m but positive tests up 58% to 174k, incl a v large 67% increase in pillar 2 (community testing, including use of lateral flow tests in those who are asymptomatic).

Big drop in performance for P2 test turnaround times.
- Regional test sites, 36% of results are provided within 24hrs of taking a test, down from 63% the week before.
- For local test sites the drop is from 51% to 22%
- Mobile test sites: from 68% to 48%

- For satellite test centres, 46% of results within 48hrs down from 63% the week before
- For home test kits it's now 38% compared with 64% last week.

And with median time to results increasing, also seeing distances people are having to travel beginning to creep up for regional and local test sites.
