This week's PHE surveillance report, 26th April - 2nd May

- despite easing of social restrictions & schools returning after Easter hols, case numbers still going down among all ages.
- still regional/local variation
- and ++concerns around variants.🧵…
Still some big differences by region - particularly looking at younger adults in Yorkshire and Humber.

Case rates in Y&H are 42/100,000, more than 3 times the rates in the SW at just 12/100,000.
This is even more apparent when looking at data by local authority.
Although some positive news as some of the differences by ethnicity and deprivation may be beginning to narrow.
In terms of incidents/outbreaks reported to PHE.

Still as low as ever for care homes and hospitals.
And a small increase in edu settings, as would be expected.

The next ONS surveillance data update will provide a little more clarity on if this is translating into meaningful increases in cases among children/young adults.
No surprises in the morbidity and mortality data, remaining as comforting as it has been in a while.
And while overall vaccine uptake remains impressive...
It masks some major differences by ethnicity, with nearly twice the percentage of people aged over 50 who are White having had two doses of the vaccine compared with those who are Black.

So much work still to be done here.
In general it all looks pretty rosy for the gov road map review in advance of 17th May.

EXCEPT for the rapidly growing concerns about variants, particularly B.1.617 (first detected in India)…
The road map decisions are based on four tests.

While things look good for the first three, the fourth is less clear. Tomorrow's update of variant data looks increasingly important.
In particular, it makes the idea of opening things further for international travel seem particularly risky.

Plus it reinforces the basics of ensuring that everyone can get tested, and has the necessary support and means to isolate.
This includes tackling ongoing structural issues like insecure work/multiple occupancy HHs. + giving local gov & health protection teams the resource, flexibility, & support they need to manage.

It'll help places with ongoing high cases AND slow local spread of variants.

Latest T&T data: wk 22-28 April

- no big shifts in numbers tested by LFDs/PCR, and ongoing fall in +ve cases

- but some interesting changes in contact tracing: fewer contacts reached and it's taking longer, and the reasons aren't straightforward🧵…
While the number of cases transferred to contact tracing fell by 12% to 10,793, the number of close contacts identified rose by 2% to 49,151.

For the first time since the start of August, avg contacts per case was >5. ImageImage
And of those contacts, the percentage reached has dropped wk on wk for the past 5 weeks, from 90% to 84%. Image

Updated our T&T performance tracker, covers 8-14th April.

Key points
- lots of changes to LFD use, with differences across the country
- despite falling cases, end-to-end journey time from symptoms to reaching contacts increasing

Detail in 🧵…
After a dip over the Easter bank holiday w/e, number of people tested increased by 15% to 4.4m

although this is still some way off the peak of 6.2m four weeks earlier
The changes have been mainly due to variations in use of rapid lateral flow devices (LFDs).

These have been rolled out by the government for people without symptoms over recent months and are now available to everyone in England.

PHE's surveillance report for 12th to 18th April now out. 🧵

Second week of school holidays for most, but some schools will have gone back.

- case numbers down & vaccination up
- persistent inequalities by geography, ethnicity, & deprivation…
Case rates & positivity continue to fall across the age groups with no clear sign of pre-Easter rise in school-age cases leading to more infection in older ages.

Highest in 10-19y/o (42 per 100,000) and lowest among 70-79y/o at just 7.2/100,000.

A pattern matched by ONS survey
Case rates also falling across all the regions, with slightly higher rates in Yorkshire and Humber (45 cases per 100,000 compared with just 14/100,000 in the SW).

Again not dissimilar to ONS and good to see case rates come down (next ONS update due tomorrow)

Having now worked it's way through the @Telegraph system: with @louisemarsha11, our take on the plans for replacing Public Health England. 🧵

tl,dr: we need a more, not less, joined up system if we're serious about health & inequalities

No £-wall🔓…
PHE is being split into the UK Health Security Agency (UKHSA which also includes Test&Trace) - focusing on external threats like pandemics

and the Office for Health Promotion - focusing on health improvement and inequalities, such as obesity and tobacco.…
As we wrote at the time, it's a risky business reorganising public health in the middle of a pandemic.…

This week's Test & Trace data - for 25th to 31st March (around the last week of school before holidays)

- LFD tests down
- big variations in LFD use across the country
- and increase contacts per case.…
The number of people tested week on week has fallen for the past two weeks, down to 4.8m from a high of 6.2m.
The fall is due to reductions in LFD use - down 23% to 5.5m.

This week's @PHE_uk COVID surveillance report, 29th March to 4th April (incl. start of the school hols). 🧵

⬇️ case rates, partly from fewer 10-19y/o LFDs with no clear sign yet of schools leading to ⬆️cases in older ages

+ important variation by region…
Further drop in cases in the most recent week following a bit of a flattening off in previous weeks - with some of this due to school holidays and fewer LFD tests.

Worth noting that for March, both REACT and ONS surveys suggest that case rates are generally static.
Big drop in LFD use, which is mainly due to a drop in test use by secondary schools (see T&T data).

The drop off has accelerated with the school holidays, but the move from testing in school to at home may have contributed over the past few weeks.
