Why UK Covid Death Toll is so High

 On 26 Jan. 2020, the death toll from Covid-19 passed 100,000. How did this happen? There is no single, simple answer, but rather a sequence of poor decisions alongside facts about the UK - age profile, obesity levels, travel hubs and more.

How countries record Covid-19 cases and deaths

The criteria for designating Covid1-9 as the primary cause of death varies from country to country. Some countries are thought to have been, or are currently thought to be, under-reporting cases and deaths. In some countries, especially in rural areas, deaths may not normally be recorded anyway. At times, Covid-19 deaths are thought to be overwhelming the reporting systems. Some countries are thought to be deliberately under-reporting the extent of their problem. Countries vary in the amount of testing carried out, which leads to mild and asymptomatic cases not being recorded.

UK Government decisions

The UK government delayed the first lockdown till March 2020, later than much of western Europe. The week between announcement and actual lockdown may have cost more than 20,000 lives as infection rates were high at this point. By May, restrictions were beginning to be eased, but may well have been too soon. Early data on transmission, infection rate and risk factors was limited and contributed to poor decisions, leading to inaccurate accusations of promoting a herd immunity strategy.

The promised 'world-beating' test-and-trace network was implemented unevenly and at a low rate. The idea was to shut down new outbreaks with comprehensive tracking by a centralised team of tracers. Unlike some other nations (e.g. South Korea and Taiwan) the UK did not have an established test-and-trace system in place ready to be activated. In the summer the UK system had teething problems in reaching contacts and low testing capacity. And low summer infection levels created a false sense of security.

Despite initial evidence that age was a factor in predicting deaths, there was a lack of protection for care home residents. By the first lockdown, the virus was rampant in care homes. Around 30% of fist wave deaths were in care homes, 40% if care home resident deaths in hospital are included.

Attempting to boost the economy, the Eat Out to Help Out scheme may be partly to blame for an increase in cases. However, testing in the summer shows there were still around 500 diagnosed cases daily, with random testing suggesting the actual level to be twice that. Positive tests rose to c.1,000 a day in late August, to c.15,000 a day in October, and in Jan. 2021 still remained above 10,000 a day on average. 

Ministers refused to order a two-week 'circuit breaker' lockdown in September, against SAGE advice. (Short lockdowns can get infection rates down, but rebound once they are lifted.) Schools and universities re-opened, providing new opportunities for virus spread.  Lockdown was introduced in November when the virus had already mutated and was spreading faster in south-east England. 

Having already announced a 5 day relaxation of lockdown for Christmas 2020, increasing numbers of cases and deaths led to a late decision to cut this to one day. 

Deep rooted problems in British society

The UK is among the ten most densely populated big nations - those with more than 20 million people. UK cities are more inter-connected than in many other places,so the virus was able to spread quite quickly. In contrast, Italy's first wave was largely confined to the north of the country.

There are affluent and deprived areas in the UK. Levels of ill health and life expectancy are worst in the poorest areas, and the pandemic seems to have made this worse. Many densely populated areas are  ethnically diverse. Official data shows mortality rates twice as high in deprived areas.

Poor state of public health - the NHS has been under-funded for many years.

The UK has an aging population. Adjusting for the size of the population, deaths have risen but not as much as some headline figures suggest. Some older people in poor health may have died of other causes during the pandemic even if they had not caught the virus.

The UK has one of the highest levels of obesity in the world. Obesity increases the risk of hospitalisation and death, with one study finding the risk of death to be almost double for those who are severely obese. [The UK ranks 6th, after the US, Mexico, New Zealand, Australia and Portugal.]

The UK has relatively high rates of other conditions (e.g. diabetes, kidney disease and respiratory problems) that also increase the risk.

UK strengths proved to be weaknesses for viral spread

The UK is a vibrant global hub for international air travel. Genetic analysis shows the virus was brought into the UK on at least 1,300 separate occasions, mainly from France, Spain and Italy by the end of March 2020. Other island nations (e.g. New Zealand, Australia and Taiwan) were able to prevent the virus getting a foothold and keep deaths to a minimum by introducing strict border restrictions and lockdowns before the virus spread too far, but they did not have the same level of virus infected travellers. UK quarantine rules for all arrivals were only in force from June 2020, and even these were relaxed for travellers from certain countries until Jan. 2021.

How have other countries fared?

Countries such as Australia have been more successful with milder first and second waves. The US never brought its death rate down in the summer as the UK did, and its death toll is catching up. Countries that had very few deaths in the first wave (e.g. Germany and Poland) are now seeing spikes and overall death rates far above usual levels.

Magnesium

 Magnesium is a crucial co-factor in enzyme reactions in the body and brain. It plays a part in heart rhythm, blood vessel health, muscle relaxation, healthy nerve function and the release of neurotransmitters (such as serotonin). 

It is thought that many people are magnesium deficient, impacting on these functions. Some studies suggest magnesium may help in relieving depression. Our need for magnesium goes up during stressful periods.

Magnesium-rich foods are: dark chocolate # avocados # nuts # legumes (includes lentils, beans, chickpeas, peas and soyabeans) # tofu (soybean curd) # seeds (especially flax, pumpkin and chia seeds) # wholegrains (wheat, oats, barley, buckwheat and quinoa) # some fatty fish (e.g salmon, mackerel and halibut) # bananas # leafy greens (especially kale, spinach, turnip greens and mustard greens.

Psychologist Kimberley Wilson takes a daily morning dose of half a teaspoon of powdered magnesium (citrate) dissolved in a glass of water.

Origins of Religious Belief

Only 16% of people are not religious: in 2018 that's around 1.2 billion people who find it difficult to reconcile the ideas of religion with what they know about the world.

A recent psychological explanation is that our evolution predisposes us to believe in an external agency, and that religion is a by-product of a number of cognitive and social adaptations which have been very important in human development.
  • We are social creatures who interact and communicate with each other in a co-operative and supportive way.
  • We have stronger attachments to some individuals than others.
  • We rely on these attachments during childhood, when making friends and falling in love.
  • We can also form strong attachments to non-human animals and inanimate objects.
  • These strong attachments can also be transferred to religious deities and their messengers.
Our relationships depend on being able to predict how others will behave in situations and time. But the things we form attachments to don't need to be in front of us to predict their actions. We learn to imagine what others may say or do through childhood pretend play and stories.

We then moved from imagining the minds of other humans to imagining omnipotent, omniscient beings. And religious texts telling of past actions fuels belief.

We are also able to anthropomorphise objects - we see a person when it is just a coat hung on a door, (and our pattern seeking tendencies lead us to see pictures in the clouds, and on slices of toast). We then endow non-human entities such as gods with human qualities.

The ritual behaviour of collective worship makes us enjoy and want to repeat the experience. Dancing, singing and trance-like states are known in many ancestral societies. These social acts, however formal, increase levels of serotonin, dopamine and oxytocin in the brain - chemicals that make us feel good, want to do things again and provide a closeness to others. 

Educational and household norms don't tend to dispute religious ideas, but do encourage challenge to early childhood ideas such as Father Christmas or the Tooth Fairy.

The impact of religion and religious thinking on human functioning continues to be the subject of intellectual debate.

Leveson Inquiry - Second Stage Axed

At the beginning of March 2018 the Culture Secretary, Matt Hancock, announced that the (Conservative) government :
  • would not implement the second stage of the Leveson Inquiry, which was due to examine relations between journalists and the police, claiming that the press had 'cleaned up its act'
  • would not put section 40 of the Crime and Courts Act (which would force media organisations to pay legal costs of libel cases whether they won or lost) into effect and would seek to repeal at the earliest opportunity.
The Conservatives opposed Leveson part two in their general election manifesto but peers voted to revive it through an amendment to the Data Protection Bill. Newspapers had lobbied hard to avoid for this outcome.

Leveson part two was scheduled to consider the extent of improper conduct and governance failings by individual newspaper groups, how these were investigated by police and whether police officers received corrupt payments or inducements.
