Seven persistent myths about Covid and lockdowns in the UK / England.

I thought I would put one thread together on what I think are 7 myths that continue to be propagated - mainly by those who, although well-intentioned, always assume that more restrictions are the answer.
1. The UK has had the highest Covid death rate in Europe during the pandemic - mainly due to being late to lockdown twice. (see myths 2 and 3)
Even compared to EU countries, the UK would be 11th on Covid deaths & 15th on excess deaths (20th in all Europe)
economist.com/graphic-detail…
2. Thousands of lives would have been saved if we had locked down earlier in the first wave.

Most of the countries with higher death rates (shown above) did lock down early & had small first waves followed by very large second waves.
Discussed more here:
telegraph.co.uk/news/2021/03/2…
3. Thousands of lives would have been saved if we had a circuit breaker lockdown last October.

Wales did have one and their excess death rate in the second wave was the same as England’s - the main impact was to postpone the peak in deaths by two weeks.
gov.wales/sites/default/…
4. The UK has the highest Covid rates in Europe now. (and this due to our lack of vaccine passports, mask mandates, etc. - see myth 5)

This is based on case rates and ignores fact that UK does a LOT more testing - you need to compare positivity rate where UK is about average.
5. Infection rates would have been much lower if England had kept mask mandate since July.

Wales & Scotland kept theirs but their rates been higher than England's for most of this period.
ons.gov.uk/peoplepopulati…
(NB. I do voluntarily wear a mask in confined indoor spaces.)
6. Only restrictions or lockdowns bring down cases/ hospital admissions / deaths.

This is clearly not true given what happened in July and September when there were no restrictions – and is most likely due to people voluntarily changing their behavior as the risk increases.
7. 'Going early and going hard’ with restrictions is always better than waiting.

Given what happened in July & September when a huge surge was predicted, that would have been the wrong advice as cases fell and actual outcomes have been well below the most optimistic scenarios.
So it’s better to admit we just don’t know what’s going to happen going forward and look at the actual data.
As I have said throughout the pandemic, such certainty is misplaced given the uncertainty of the evidence on this - and on many interventions.
None of this is to downplay terrible toll of Covid with the loss of so many lives - which I did what I could to reduce by serving on the frontline.
And there are times when lockdowns are needed to prevent the NHS being overwhelmed as happened before - & harmed all our patients.
Finally, of course it is legitimate to question and criticise the UK's/England’s response to Covid - and what we can learn from it and other countries experiences to save lives in the future but it should be based on facts and not on misleading claims/selective use of statistics.

To those calling for a return to restrictions, a reminder of some criteria I set out last year that should be used before suppression measures are implemented:

i) Evidence for effectiveness in reducing cases
(particularly in over 60s) hospital admissions & deaths

(1/4)
ii) Evidence that a mandatory approach produces better outcomes than a voluntary one.

iii) Evidence that a blanket approach produces better outcomes than a targeted one. e.g. on adherence, suppression

(2/4)
iv) Evidence for broad public acceptability with high levels of sustainable adherence.

v) Most importantly, that the intervention has been shown through transparent impact-benefit analysis to produce less overall harm. (Health in QALYS, cost per QALY saved.)

Would an earlier lockdown really have saved tens of thousands of lives?

A thread summarising the main points of my article earlier today. (References at the end.)
Many people have claimed that if only the government had ‘followed the science’ last year and locked down a week earlier and closed our borders - as other countries did - we could have saved tens of thousands of lives.
I have tried to look at whether an earlier lockdown really would have reduced our eventual death toll over both waves. I have relied not on the models on which these claims are made, but looked at what has actually happened in Europe over both waves to date.

My final thread of the year - a brief review of the current situation and why I think the govt. is right to resist calls for another national lockdown.

Throughout this pandemic I have tried to stress the twin dangers of fear and complacency -
– excessive fear harms our mental (and overall) health and led to the deaths of thousands in the first wave who were too scared to seek medical help when they needed it. And complacency about the real risks of COVID leads to riskier behavior and increased spread of the virus.
Many recent headlines highlight record numbers of cases and increasing deaths with calls for another national lockdown. And of course it is true that the situation is getting worse but it is important not to panic people by exaggerating the threat but to give the true picture.

A thread on some early evidence on the impact of the new COVID variant - increasing cases, increasing hospital admissions but not yet the expected increase in deaths.

Is the new variant less deadly?
Generally, over the course of the second wave, we have seen a pattern of cases rising overall and then in the over 60s - which is then followed by hospital admissions rising with a 1-2 week lag, and then deaths with a 1-2 week lag.
However, as shown in the figure below, that pattern seems to have changed since cases linked to the new variant started increasing rapidly at the end of November with admissions increasing as expected, but not deaths.

Plan B:
Why Sweden provides a potential model for us to follow - but not for the reasons most people think - and only if we learn from their mistakes.

And why - whichever plan is chosen - we need to build consensus. And how that could be done.
No country has received more attention for its approach to dealing with COVID than Sweden but there continue to be widespread misunderstandings of its strategy - with many thinking they followed the approach outlined in the Great Barrington Declaration.
However, the actual, official Swedish government strategy is ‘to limit the spread of infection in the country and by doing so, to relieve pressure on the health care system and protect people’s lives, health and jobs.’

And as its Chief Epidemiologist, Dr Tegnell has said,

A brief review of where we are - & why we need a plan B.

In general, I think the current government strategy of suppression to keep cases low enough to maintain NHS services and minimise non-COVID health harms while protecting education and jobs is a reasonable compromise.
Furthermore, if virus levels get too high, fear increases and people don’t come to hospital, don’t go out and the economy suffers, etc. I also understand the governments rationale of not wanting to reintroduce shielding due to the mental (and other) health harms it would cause.
I also support the targeting of restrictions based on the local level of cases as opposed to blanket national ones. I find it hard to understand how it can be possibly be fairer to destroy jobs and businesses all over the country including in areas where hospitalisations are low
