Apparently the government are planning to tell doctor's to "sign fewer patients off sick" to reinvigorate the economy.

Unfortunately, just telling people they are not sick, doesn't make them not sick, so I think this plan will probably fail.
Lets have a look at the data.
🧵
1/12
Firstly, we saw a sharp rise in the UK sickness absence rate from 2020 to 2021*.

This is the highest level since 2009.

*2022 data is not out until April.

2/12
The pandemic has had a number of different and potentially conflicting impacts on these data.

It's possible that measures such as furloughing, social distancing, shielding and increased homeworking may to have helped reduce other causes of absence in 2020...
3/12
However, a large part of the uptick we saw in 2021 was undoubtedly due to covid.

The return to pre-pandemic working patterns and the cumulative impact of millions of covid infections have taken their toll.

You can clearly see rises in every age group in 2021.
4/12
If you look at the industries that had the highest sickness absence rate, you can to see "Human health and social work" right at the top, followed by "transport and storage".

These are two industries (particularly the first) highly likely to be impacted by covid.
5/12
If you look at the main reasons people were off work unwell in 2021, COVID is the first single identified reason (second behind the cumulative total of "other").
6/12
Even in 2020 (grey bars) - despite only being recorded for 3/4 of the year and the suppression measures we underwent - covid was still the fourth most common reason for being sick off work.
7/12
We know large numbers of people have been off on long term sick leave with Long Covid.

Again, it's not surprising to see Social care, Health Care, Education and Transport near the top of the list of sectors affected.
8/12
Large proportions of these people off sick with long covid find that it is limiting their activity either a little (orange) or a lot (red).

Is it going to help to deprive people of a fit note if they are not able to do their job?

I would suggest, not.
9/12
If we really want to do something about tackling workforce absence then one thing we could try is reducing the number of people who are getting sick with covid.

Here's a bunch of ways we might go about doing that (ventilation, filtration, masks...)
10/12
theconversation.com/covid-treatmen…
Another thing we might think about doing is improving sick pay so that people of the UK are allowed the requisite time they need to recover (and not to infect others with e.g. covid).

We rank a long way behind many of the European countries we might compare ourselves to.
11/12
It's certain that we have a problem with sickness absence.

In Nov. former Chief Economist at the BofE Andrew Haldane warned of the economic consequences of an unhealthy population.

Forcing unwell people back to work isn't the answer to the problem.

With thanks, as always, to Bob Hawkins, for his help preparing the data.

A quick update 🧵on the covid situation in the UK at the moment.

TL;DR After rising for the last couple of weeks things seems to be slowing down and covid incidence rate may even have peaked.

1/9
The ONS infection survey is just catching up with the latest rises

All nations (except NI) have seen rises

Remember it is around two weeks out of date (these data are for the week ending 7th Feb).

So we will expect to see these numbers rise for another couple of weeks yet.
2/9 Image
The latest week saw rises in all regions of England...

ONS infection survey picking up the flattening-off of COVID cases that we saw a couple of weeks ago.

Remember you might see reports (based on these data) today suggesting covid cases are flattening.

In reality we know they've been rising for almost two weeks now.
Zoe infection survey picked up the rise much earlier.

They've recently recalibrated their numbers to better match the historical numbers from the ONS to give a more accurate picture of the absolute levels.
In greater detail you can see rises in prevalence in England and Scotland and falls small falls in Wales and NI, although, of course, all these estimates are subject to some uncertainty.

Covid Hospital admissions continue to rise in England as another wave of covid spreads across the country.

Not hearing much reporting on this in the media.
Seems like we have just come to accept that this is what happens now.
1/3 Image
Hospital admission rates have increased in every region of England, with particularly steep rises in the East of England - although the South East. North East and the Midlands are flatter.
2/3 Image
Admissions rising in all age groups, but as always the biggest increases tend to be seen in the older age groups.

A short thread on ONS infection survey prevalence data.

ONS is suggesting prevalence is falling, but remember their data is lagged by around two weeks.

In reality prevalence is probably rising reflecting the rises in covid hospital admissions we are seeing.
1/5
Prevalence (when measured) seemed to roughly even across the four home nations.

Each nation saw a fall over the last reporting period.
2/5
All the regions of England also saw a fall (except perhaps for the North East).

A quick thread on where we are with covid ahead of the @IndependentSage session this afternoon.

TL;DR - Covid cases are starting to rise again as are hospitalisations, while vaccination has virtually stopped.
1/7
CH.1.1 & XBB.1.5 sub-variants are growingly slowly in their proportion of sequenced cases and now account for around 40%.

Only 6% of people in England are within 3 months of their most recent vaccine dose and only 30% within 6 months. Everyone else is >6 months out.
2/7
Zoe symptom tracker app is showing some rises in prevalence, which have been preceded by rises in incidence for a while now.

(Zoe might not be perfect for absolute numbers, but is probably our leading indicator for trends).

ONS infection survey is just out.

Good news is that we've seen big drops in prevalence across all four nations.

🧵
1/6
England now has the lowest prevalence of any of the home nations, followed by Scotland.

Worth bearing in mind, however, that prevalence is still above 2.5% for all home nations.

Prevalence dropping uniformly across all regions...
