Dissecting COVID-19 Mortality Rates

Coronavirus (COVID-19) pandemic is inflicting unprecedented havoc all over the world not only on human lives but also on social, economic, educational and political spheres. The most devastating part is that as scientists, medical professionals, virologists, epidemiologists and so forth come up with a potential cure or preventive medicine, they find that the virus had subtly changed in the meantime such that the medicine is no longer as effective as it is meant to be. It is a sort of cat and mouse game between scientists and the nature, where scientists are pursuing the naturally evolving deadly virus with all its technical arsenals and the nature is changing the characteristics of the viruses to outwit scientists. So far, over the past five months or so, nature is having the upper hand!

Now, setting aside the biological aspects of this devastating virus, parallel work had been going on to find out who the victims were and what were the inherent characteristics of the victims. If these characteristics could be identified precisely, then from the traits of these characteristics adequate protective measures can be prescribed and the likelihood of future damages can be reduced.  

In order to do that, one needs to have sufficiently large database of victims spanning over a period of time covering variables such as races of the victims, genders, demographic distribution, socio-economic conditions, living standards and lifestyle choices, religious adherence etc. Underneath all these variables, there may be few dominant traits which cut across these variables to perpetrate this disease within the population. To filter out these traits, one needs to dissect the mortality figures attributable to various factors.

The overall findings of the Office for National Statistics (ONS) over the past three months or so in England and Wales concur with the statistics in other multicultural and multi-ethnicity countries that black and Asian people, collectively known as Black, Asian and Minority Ethnic (BAME), were at higher risk from the novel coronavirus. But within this overall group, there are sub-groups where the risks are widely distributed – the risks vary on economic grounds, on educational grounds, on professional grounds as well as on religious grounds. But in all of these sub-groups, risks of BAME are higher, sometimes significantly higher, than the corresponding white sub-groups’. However, this article concentrates on risks based on religious subgroup.    

What had been identified from the study of mortality rates over the past three months or so in England and Wales was that religions offer a significant factor in fatality figures. Of course, other factors associated with the religious factor such as communal gathering in private houses, distributing and sharing of food items on religious occasions etc may have played significant roles as underlying causes in increasing the fatality figures. Let us look at the overall statistical figures before going into the underlying causes.

The ONS analysis of the mortality figures in England and Wales from March 2 to May 15 show that Muslims, Jews, Hindus, Sikhs and Christians have mortality rates in that order with the Muslims being the highest. The lowest rate is among people who have no-religion. Although the religion of a deceased person is not required to be specified in the death certificate, the ONS had to coordinate the deceased person’s religious affiliation from the 2011 census data, which are the latest available figures. Table 1 shows the percentage distribution of population of various religious groups. It may be noted that study population distribution is somewhat different from the 2011 Census distribution, as some people in the Census may since have passed away or emigrated and hence not available in the study population.

2011 Census
percentage distribution
Study population

No religion25.126.0
Other religion0.40.4
Not stated or required7.27.0

It had been found that the mortality rate among Muslim men was 98.9 deaths per 100,000 (of Muslim men) and 98.2 deaths per 100,000 for women. For those who said they had no religion in Britain’s 2011 census, the figure was 80.7 deaths per 100,000 males and 47.9 deaths per 100,000 females.

However, when the age-standardised mortality rates (ASMRs) involving COVID-19 were evaluated, the deaths among Muslim religious group became 198.9 deaths per 100,000 males and 98.2 deaths per 100,000 females, which were the highest rates. The corresponding figures among Christians were 92.6 males and 54.6 females. The lowest figures were among those with no religious affiliations; the corresponding figures were 80.7 males and 47.9 females. ASMR is a statistical measure to allow more precise comparisons between two or more populations by eliminating the effects in age structure by using a “standard population”, which is taken as the European Standard Population.

Religious groupMalesFemales 
No religion80.747.9 
Other religion or not stated84.249.2 

The ONS report states that with ethnicity included, it demonstrates that a substantial part of the difference in mortality between religious groups is explained by the different circumstances in which members of these groups are known to live – for example, living in areas with higher levels of socio-economic deprivation and differences in ethnic makeup. The adherents of various religions have different levels of education and career pursuits and that may lead to different socio-economic strata.

Figure 1: Muslim, Sikh or Hindu had higher mortality rates compared to the Christian and no-religion populations

Age-standardised mortality rates of death involving COVID-19 for those aged 9 to 64 years by sex and religious group, England and Wales, 2 March to 15 May 2020. It may be pointed out that, for example, ASMR in Muslim males between 9 and 64 is about 47 per 100,000, whereas for the whole population of Muslim males, i.e. age 9 to 64 and 65+, the figure is 198.9 per 100,000. That shows that the mortality in the age group 65+ is 151.9 per 100,000! Thus, the 65+ Muslim group is over 3 times more vulnerable than the under 65 group in England and Wales!

It had also been found out that the highest mortality rate was among black men at 255.7 per 100,000 compared to a rate of 87 deaths per 100,000 white males. The death rate was 119.8 per 100,000 for black women and 52 per 100,000 for white women.

Thus, COVID-19 pandemic had identified the vulnerability of population as a whole and the various subgroups of population. From those sub-groups the underlying causes such as economic deprivation, lack of education, concentration of people in the community, lifestyles, social patterns, religious adherence and many other factors may be identified.

Economic measures we should take in response to COVID-19 in Bangladesh

The 2020-21 budget of Bangladesh, under preparation now, could have been exciting. The country was having an unbroken run of 6 percent or higher growth rate for the last nine years. In 2019, it reached 8.2 percent. Poverty declined to reach 24.3 percent in 2016 (World Bank). Export earnings and remittance income, put together, covered more than three-fourths of the country’s import bill, and the country’s debt service ratio was at a comfortable level of 5.7 percent (in 2018). The achievements in the social sectors (in child and maternal mortality, in education, and nutrition) were praiseworthy, better than many other countries at similar levels of income.  

A number of mega projects involving huge expenditures (such as the Padma Bridge, Deep Sea Port, Rooppur Nuclear Power Plant, Karnaphuli Tunnel, Metro Rail Project) were taken up to develop and modernise the country further. The country was looking forward to celebrating 50 years of its independence (towards the end of 2021) in style.

COVID-19 pandemic has put an end to this euphoria. The highly contagious virus, with its high toll of human lives and livelihoods, pushed the world to a recession. The IMF estimates the world GDP to shrink by 3 percent this year. With supply chains broken, factories, trades and businesses either closed or nearly so, unemployment is expected to rise. The level of unemployment has already reached 26 million in the USA and 22 million in EU. The World Health Organisation (WHO) warned that the virus had not reached its peak yet, and that there could be multiple spells of the virus.

Bangladesh has not been spared either. Although the impact of COVID-19 in terms of infection and fatalities (going by official statistics) remains lower than some developed countries, the casualties (which do not include community deaths and deaths in hundreds of private clinics around the country) can mount in the coming months. Like in most other countries, Bangladesh also imposed lockdown measures. Educational institutions, non-essential services, offices, shops and transportation services, small, medium and large industries including the vibrant and major foreign exchange earner, the readymade garment (RMG) factories, have been closed down.  However, some are opening slowly in recent days after the relaxation of lockdown measures.

The World Bank estimates a sharp decline of Bangladesh’s growth rate to around 2-3 percent in 2020, and further to 1.2-2.9 percent in 2021 from the 2019 growth rate of 8.2 percent. These are way below the 7-8 percent growth needed to reach the middle-income status by 2024.

The lockdowns have seriously disrupted normal economic and social activities in the country. Millions of workers engaged in shops and restaurants, in transport and communication sector, working as domestic help, self-employed as traders, hawkers, day labourers, totalling anywhere between 15-20 million, are expected to lose their livelihoods. With the closure of the readymade garment (RMGs) industry, another four million employees, mostly young women and their families, are expected to face difficult economic and social condition. Their low incomes make them vulnerable even to short periods of unemployment. 

Fear of the virus as well as loss of income are driving thousands of these vulnerable low income urban people to their rural roots. Others, who do not have this option, are staying back in urban slums, where congested living can be the breeding ground of the virus.

Given this background of unprecedented economic and social circumstances, the budget of 2020-21 will have to be significantly different from what could have been an “euphoric” budget. Instead, the budget will be one of damage limitation, caused by external circumstances and rebuilding.

The emergency measures are expected to tackle the emergencies created by the COVID-19 pandemic (in terms of both halting the progress of the virus and providing medical care to those infected), and supporting people survive through their immense economic hardship. The rebuilding measures, on the other hand, will address the issues of restarting the economy with directed support, subsidies, grants, and helping to build institutions to tackle future pandemics, including resurgence of COVID-19.

The emergency measures will have to focus on expanding the capacity of public healthcare institutions, through infrastructure development, procurement of equipment (PPE, masks, ventilators) and medicines (both anti-COVID-19 and for curing COVID-19 infection), and of course providing due support to all medical care staff, most importantly to the frontline care staff. And it will also have to beef up the country’s poor social protection initiatives (which is lowest in the Asia Pacific Region: UN Asia Pacific Region Report April 13, 2020). Part of the prime minister’s cash incentive of about 95.6 thousand crores taka could give the social protection initiative a boost, as well as provide cash incentives to medical workers.

The rebuilding measures, on the other hand, will focus on those sectors which are the main drivers of the economy, i.e. restarting RMGs, facilitating the repatriation of those who might have gotten stuck in Bangladesh. The measures could also include working capital support to small and medium industries, and small loans to traders. Low interest loans could also be provided to small businesses and industries who would like to configure their factory floors and work spaces to conform to the need for social distancing, to avoid further spread of COVID-19.

Beyond these, it will be immensely worthwhile to support agriculture, especially the smallholder farmers, through small loans to farmers, subsidised inputs, water and uninterrupted electricity supply during the dry season (now) and through ensuring availability of seasonal labour for harvesting. Microfinance institutions (MFIs), refinanced by Bangladesh Bank, could play an effective role in this area.

RMG sector, a major foreign exchange earner of the country, and employer of nearly four million workers (mostly for women), will need to be beefed up as early as possible. There could be a special fund to provide subsidised loans to the RMG industries on a case by case basis, judged by their ability to restart production, export and re-employment of staff laid off during the COVID crisis.

All these measures, detailed out and costed, will be a very tall order. The critical issue is how to get the budget financed.

The pandemic related crisis will severely restrict the growth of Bangladesh, and also imports, through reduction of economic activities. Both of these will severely reduce the government’s ability to raise revenue; the latter through reduction of revenue from import duties. The country will have to borrow: from external sources to the extent they are available, but also from domestic sources. These will create inflationary pressure, both because of reduced supply response and lower imports. The challenge will be to channel support to activities which could quickly respond through increased production.

Building a sustainable society in the age of climate change

In an article published in this website May 15, 2020, I discussed the future of our planet within the context of frontier ethics. The main conclusion was that frontier ethics, which affects our attitudes about the seriousness of environmental problems, will eventually lead to massive resource depletion and ecological disasters, and accelerate the pernicious effects of climate change.

Those who believe in frontier ethics are least concerned about the declining fossil fuel reserves because they are convinced that reserves will never become dry. Their mantra—”Why be efficient if resources are unlimited”—prevents them from using available resources more efficiently. Instead, they maintain that we should increase the search for new reserves, even if it takes us into one of the few remaining pristine wilderness on our planet.

A classic example of someone who preaches and practices frontier ethics is Donald Trump. After becoming president of the United States of America, he signed an executive order opening up the entire coastal plain of the Arctic National Wildlife Refuge in Alaska to oil and gas exploration. Until then, it was an environmentally sensitive area long closed to drilling. Furthermore, he gave the coal industry in America a carté blanche to dig wherever there may be signs of coal. He also repealed former president Obama’s Clean Power Plan, giving states more flexibility to keep coal-fired power plants open.

Arguably, societies that believe in frontier ethics are low-synergy societies treading on a path of unsustainability. In contrast, high-synergy societies live in harmony with nature and they seek ways to enhance natural systems. Creating a high-synergy society that lives within the Earth’s means is possible if we adopt a set of sustainable ethics that ensures future generations and other species the resources they need to survive.

The tenets of sustainable ethics are: The Earth has a limited supply of resources, and they are not all for us; humans are a part of nature, subject to its laws; and success stems from efforts to cooperate with the forces of nature. Clearly, sustainable ethics recognises our place in the natural order as one of many millions of species and they favour cooperation over domination. Also, they are diametrically opposed to the tenets of frontier ethics. While frontier ethics leads to exploitive behaviour, sustainable ethics will lead to a less exploitive human presence that can endure for thousands of years.

In addition to the three tenets, there are at least six principles that lie at the core of sustainability. They are conservation, recycling, using renewable resources, restoration, population control and adaptability. Among other measures discussed below, if we follow these principles, we can create and maintain a well-functioning global ecosystem.

In order to build a sustainable society in which future generations and other species can survive and live well, we have to change our thinking process too—from linear to system thinking. Linear thinking sees events in a straight-line sequence, ignoring a complex web of interactions, while system thinking recognises how entire systems function. In the environmental arena, system thinking helps us to see how individual parts work together and how interdependent all life forms are. By becoming better system thinkers, we can learn to avoid impacts that threaten the health and wellbeing of the planet and its organisms.

Because system thinking encourages us to look at the whole, it will naturally force us to look at the root cause of problems, especially environmental ones. Additionally, it can help society to identify key leverage points as to where changes can be made. Moreover, system thinking will enhance our ability to see the big picture as well as connections between various parts that are essential to solving the many environmental problems, particularly those caused by climate change, and putting us on a sustainable path. Unfortunately, most of the world leaders are not system thinkers and therefore cannot guide us toward a sustainable society.

Building a sustainable society requires widespread participation with input from the rich and poor, conservative and liberal, young and old. In fact, sustainable solutions call for action from large and small businesses, individuals and governments. Individuals are important because each one of us is part of the problem. In other words, seemingly insignificant actions by us, albeit small, are responsible for many environmental problems we are facing today.

Achieving a sustainable world also requires massive cooperation between citizens and governments. Cooperation must occur on a much grander scale, with countries working together for the common good of their citizens and the planet. At the same time, we have to develop a unified strategy to fight the unique challenges posed by climate change.

But how do we achieve this cooperation and develop a unified strategy in an era when climate change is an impediment towards sustainable development? Since 1995, world governments have met every year at the so-called Conference of Parties to forge a global response to the climate change emergency. However, besides stating lofty goals, these dysfunctional conferences were either fractious or soporific. Interspersed with moments of rare triumph though, such as the Paris agreement in 2015, they mostly failed to deliver strong commitments to tackle the terror unleashed by climate change.

In the meantime, the impact of climate change on humans, animals and the environment are becoming increasingly unbearable. It is dragging millions of people into grinding poverty. That being the case, virtually no one any longer believes that these conferences will ever be able to tackle climate change, thereby allowing us to lead a sustainable life. If it sounds downbeat, that is because it is.

So how do we create a sustainable future? As noted by Einstein, “In the midst of every crisis, lies great opportunity.” Indeed, from the current crisis caused by the coronavirus pandemic, we can observe some encouraging trends in our behaviour and lifestyle that have profound implications in the fight against climate change. If we can hold on to these trends in the post-pandemic world, we will be able to face the ongoing existential threat of climate change effectively and thus create a sustainable society.

Our frontier mentality and the Future of Earth

No one witnessed the birth of Earth. The Earth does not have a birth certificate to authenticate its age. But there is no doubt about Earth’s antiquity. It is 4.55 billion years old. In the context of the Universe which burst into existence 13.7 billion years ago, Earth is in its early middle age. It will live for another five billion years, when the Sun will become a Red Giant, swallowing the nearby planets and ending its luminous career by dwindling into a white dwarf.

Although Earth is very small—a mote of dust—in the vast cosmic arena, it is the only planet that is filled with exquisite beauty, a cornucopia of boisterous wildlife slithering, scampering, soaring and swimming all over the planet. It showcases timeless marvels—a panoply of wonders—sculpted by Nature over millions of years. It is home to towering mountains, alpine glaciers, lush green rainforests, subtropical wilderness and millennia-old humongous trees, gushing geysers, beautiful coral reefs, lofty waterfalls and pristine lakes. The Earth is also home to incredible sandstone arches, deep canyons, varicoloured petrified wood and multi-hued badlands, massive caves filled with imposing stalagmites and stalactites, sparsely vegetated and colourfully painted deserts, gigantic sand dunes, and hundreds of species of flora and fauna.

Evidence of life—bacteria and single-celled organisms—date to 3.85 billion years ago. Since then, life suffered wave after wave of cataclysmic extinctions. The dinosaurs are perhaps the most famous extinct creatures who roamed the Earth’s surface unchallenged during the Mesozoic Era. After surviving for nearly 165 million years, they became victims of the greatest mass deaths in the history of our planet 65 million years ago when a large asteroid hit the Earth.

About 25 million years ago, most of the present day species emerged. Now, fast forward to about two million years ago and we see the evolution of our ancestors—upright, biped, primate mammals. Evidence shows that modern humans originated in Africa within the past 200,000 years, yet there was no move toward high level civilisation. It was the Sumerians of Mesopotamia who developed the world’s first civilisation roughly 6,000 years ago.

We have had the planet to ourselves for a small fraction of time. During this short time interval, we outfoxed other species in the game of survival. Maybe they ran out of luck in evolution’s lottery, or perhaps sometime in the distant past, we became completely dissociated from the checks and balances between man and nature and became a super-predator.

Since the beginning of the Industrial Revolution circa 1760, we made a toxic mess of our natural environment, resulting in an ever-hotter climate, melting glaciers, rising sea levels, widespread droughts, frequent and much wilder storms, crop failures and tens of millions of climate refugees. Our unrestrained use of fossil fuels for more than a century had been slowly pushing the planet toward climatological catastrophe.

Today, we are fixated on enjoying the present and refusing to account for the consequences of our actions on tomorrow. Social scientists interpret this type of behaviour as frontier ethic, prevalent in Western culture as well as others. This ethic embraces a rather narrow view of humans in the environment and even a narrower view of nature. It is characterised by three tenets.

The first is that the Earth has an infinite supply of resources for exclusive human use. There is always more and it is all for us; humans are apart from nature and immune to natural laws; and human success derives from the control of nature.

This tenet no doubt evolved in the prehistoric time when human numbers were small and the Earth’s resources did indeed appear inexhaustible. Not anymore. The massive increase in economic activity and the upsurge in population growth in the last 200 years have brought us face-to-face with the planet’s limitations.

The second tenet sought to position humankind outside the realm of nature. Many people still continue to view human beings as separate from nature and persist in thinking we can do whatever we please without harming the planet. To the contrary, our independence is an illusion, engendered by our remoteness from a world we see through rose-coloured glasses and thermo-paned windows.

As for the third tenet, industrialised nations view nature as a force that must be conquered and subjugated. Hence, we manipulated wildlife, fisheries, land, rivers, oceans and forests like so many pieces in a board game, until the environment reached a dangerous point of disequilibrium.

Over the years, the frontier ethic permeated our lives so much that we became more remote from the natural world outside our artificial environments. It influences our personal goals and expectations without thinking about the effects on the long-term health of the planet.

It cannot be overemphasised that the fate of the planet, our home, and the millions of species that share it with us, as well as the fate of all future generations, lies in our hands. Do we realise that because of resource and ozone depletion, global warming and other problems, the human species will be wiped off the face of the planet if we do not change our lifestyles? At the least, things will deteriorate to the extent that we could lose centuries of technological and economic progress in the next few decades. Our wonderfully diverse biological world, the product of billions of years of evolution, could be eradicated in a fraction of the Earth’s history.

So, what should we do to keep the planet habitable for our future generations? Scientists have urged world leaders in vain to combat global-warming emissions, which have only continued to soar upward. Should we instead rely on a pandemic, such as the coronavirus that is shutting down countries across the globe, slowing down economic activities, halting industrial productions and travel, thereby causing a significant decline in air pollution and carbon/nitrogen emissions all over the world?

The coronavirus pandemic is a tragedy—a palpable human nightmare unfolding in overloaded hospitals with alarming speed, racing toward a horizon darkened by economic disaster and chock-full of signs showing more sufferings to come. This global crisis is also an eye-opener for the other global crisis, the slower one with even higher stakes—anthropogenic climate change.

The cure due to coronavirus is temporary and totally unacceptable, whereas the threat from the adverse effects of climate change will remain with us for years, unless we shape up pronto. Nevertheless, coronavirus should make us wonder if lessons learned from the pandemic might be the beginning of a meaningful shift from business-as-usual attitude.

On this International Mother Earth Day, let us pause for a moment and imagine what the Earth would look like when it will be bereft of mirth, when there will be no wilderness and wildlife, when lakes will be filled with sudsy waters, when coastlines will become unrecognisable and when the air will become a witch’s brew. Can our planet still be called Earth? The answer is no, because we do not have the insight to predict the consequences of our frontier mentality and exercise restraint where we must.

I end the piece with the following words of wisdom from the Native American Chief Seattle. “The Earth does not belong to man, man belongs to the Earth. All things are connected like the blood that unites us all. Man did not weave the web of life, he is merely a strand in it. Whatever he does to the web, he does to himself.”

Coronavirus pandemic – opening the eyes

Human beings had been fighting against the nature, against other animals and even against other human beings for centuries; in fact, ever since human consciousness arose. In doing so, the prevailing science and technology and natural defence were the main armoury of human beings. But now this little virus called Covid-19, so little that it is invisible even to the microscopes, has brought home to human beings in no uncertain terms that human existence is at the mercy of this virus or any similar strain of virus or mutated viruses.

What is this insidious virus that has brought virtually the whole world to a standstill, that is banging the heads of ardent capitalists, committed communists, socialists, devoted Muslims, Christians, Jews, Hindus, Buddhists, mullahs, ayatollahs, rabbis, priests, atheists, agnostics and all other strands of human dogmas come together to fight against it? Political, social, economic, religious divisions are now totally irrelevant against this virus. This virus does not distinguish or differentiate between the prime ministers, presidents, princes, ministers, millionaires, billionaires and destitute, paupers, street beggars etc. This virus can strike anybody at any time and that’s why it is a pandemic now.

This coronavirus is a virus – a miniscule biological entity, a microscopic parasite – that can infect living organisms. The coronavirus is a collective name for a group of viruses that covers everything from common cold to Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). The covid-19 is a particular strain of coronavirus which had popped out, or one can say evolved, only a few months ago (in late 2019) in the wholesale fish market in the city of Wuhan, China. However, Covid-19 strain is somewhat different, more aggressive and contagious than SARS or MERS. Even Covid-19 has a number of strands

This Covid-19 is a variant of SARS that can go from human to human in aerosol form and through body contacts. Although some virologists speculate that it may have jumped from animals or reptiles to humans through food chain, there is no definitive evidence to support this hypothesis. Few days ago, there had been a report that some animals in the zoo in Bronx, New York had developed coronavirus symptoms, probably due to infection from zoo-keepers. This means that this virus or some variation of this virus has the ability to jump back and forth between men and animals.

The virus consists of a nucleic acid molecule (typically RNA or even DNA) with a protein coating to protect itself and distinctive spikes at the outer surface to anchor into a particular type of human cells. As it is a virus, it hasn’t got the ability to replicate itself and multiply. Nevertheless, it does want to survive, as all genes do, by multiplying and moving from body to body to improve its chances to live. To survive and replicate, it needs to find a host cell where it can make use of host cell’s genetic material and protective coating and then it strangulates the host cell so that the host cell cannot hit back and the host cell gradually withers away and dies. This virus when multiplied many times within the safety of a host cell bursts open and spreads out and each one of them then attacks surrounding cells and the process proliferates.

The victory by the virus following the first attack is by no means a smooth affair; it’s a bloody war. When the parasitic virus attacks the body, the immune system of the body (which is a system of proteins and cells that are distributed throughout the body) responds to the invasion. These proteins include antibodies, which lock on to the bits of the virus such as the spike ‘S’ protein. It was this spike ‘S’ protein that was used by the virus in the first place to home in to the body cell and go through the cell membrane. Now this very spike is used by the defence mechanism of the body to identify and target the virus.

Thus, the immune system tries very hard to exterminate the invading virus. A life and death struggle ensue; the virus (Covid-19) knows that unless it can colonise the host cell, it will die and the host cell also knows that if the invading virus wins, it will suck life out of it and the cell will die.

Thus, the immune system tries very hard to exterminate the invading virus. A life and death struggle ensue; the virus (Covid-19) knows that unless it can colonise the host cell, it will die and the host cell also knows that if the invading virus wins, it will suck life out of it and the cell will die.

As this struggle continues, the host body – the survival machine – is blissfully unaware of what is going at the cellular level. There is no outward symptom, no discernible ill effects. It is called the asymptomatic condition meaning no symptoms. After a few days, if the body immune system wins, the invading viruses are crushed and disposed of. On the other hand, if the invading viruses start winning and keep attacking cells after cells, alarm bell starts ringing and messages go out throughout the body that it is under attack. The organs which are lost or partially lost start showing up symptoms. These are sore throat, headaches, persistent coughing as respiratory tract cells gradually become dysfunctional and high body temperature. There may be reduced functionality of other body organs. For example, there may be loss of appetite, aches and pains, dizziness etc.

The body nonetheless keeps fighting. If the invading army of viruses attack and destroy lung cells, which in turn affect alveoli sacs, breathing becomes difficult and artificial breathing using oxygen masks and, in extreme cases, ventilation units may be required to supply oxygen to the body. All is not lost even at this stage and the body can recover. It is anticipated that at least another week or so would be required to recover. However, if there are pre-existing health conditions wherein the immune system was weakened already, such as pre-existing diabetes, heart conditions, kidney problems etc., then the chances of recovery become that much difficult.

Once the viral attack has been successfully overcome, the cells of the immune system would ‘remember’ the virus and its characteristic make-up and any future attack by this virus would be immediately repelled. However, this immune system memory would not last for very long period. Normally two to three years is the maximum for this memory.

To counter this virus, a vaccine is needed to be developed. The vaccine is likely to be a harmless subcomponent of the virus, and the idea is that the vaccine would stimulate the immune system, to develop antibody by lymphocytes and get the body well prepared in anticipation of viral attack.

The presumption among the political and economic leaders of the world is that once the immediate Covid-19 pandemic is overcome and the fatality figure is brought down to nil, everything can be scaled down and life will turn normal again. The reality is likely to be far from this situation. When fatality is brought down to zero in an area or in a country, it does not mean the virus is finished; it is just contained away from human beings. It can come back at any time, despite some precautionary measures.

The graph above shows that a physical system – an earthquake, a disease, a pandemic and so on – may appear multiple times, albeit in damped condition, after the first incidence. The first peak may be much bigger than the second peak, but the second and subsequent peaks cannot be ruled out. Moreover, the time gap between the peaks would depend on the measures taken to terminate such occurrences. The Spanish Flu of 1918 is a case for pandemic example; it came back and ravaged the world number of times over a number of years. So, every precaution must be taken to counter such recurrence.

Admittedly this pandemic is causing untold misery and pain to millions or billions of people round the world. The economy of each and every country is suffering and will bear unimaginable strain due to this pandemic. The social structure is irrevocably strained: social gatherings, public performances, national and international sports and games would be severely curtailed, if not completely abandoned. The education system is at doldrum. In fact, everything that the present civilisation pursues has to be reconsidered.

But much of it, if not all of it, is due to our unbridled activities, as if there is no tomorrow. The Earth had been poisoned endlessly with greenhouse gases (CO2, NOx, CFC etc) leading to unprecedented global warming – the devastating impacts of global warming are yet to come, the Earth and the seas are endlessly exploited, the population is going up and up and within 20 to 30 years it is likely to be over 12 billion. The worst thing is that there is no recognition that we are destroying this planet.

Take, for example, the actions of Donald Trump, the president of the most powerful and flamboyant nation on Earth. He has withdrawn America from the Paris Agreement of 2016 (UN Framework Convention on Climate Change) meaning that he can pursue whatever he wants to do regardless of what happens to Earth’s climate. Only about a month ago, he was dismissive of coronavirus as a common flu and asked people to have common flu precaution. Now, when thousands of Americans are dying in all major cities every day in America, he is blaming the States for not taking measures in time!

Political leaders must understand that short term measures to boost their public rating are causing long term damage to the Earth and the livelihood of common people who live on it. The leaders must be made to bear the consequences of their actions.  World order needs to be rearranged and made favourable to the Earth. Otherwise, the existence of humanity will be at stake.
