Coronavirus explained: Why experts say more countries need to search for new Covid-19 mutations

In late November, scientists in the UK detected a troubling new Covid-19 variant.

Growth of the strain, which had been circulating at “very low levels” until two weeks previously, was on the turn.

And it was about to explode across the south-east of the country.

The variant first came to light when experts were investigating why infection rates in Kent were not falling, despite severe restrictions being in place.

Genetic sequencing of SARS-CoV-2 samples in the area revealed a cluster of the B117 strain, which came to be known as the Kent variant, spreading rapidly into London and beyond.

Tests showed the variant first emerged in late September.

At the end of October the strain accounted for only 3 per cent of cases in England.

But by the start of February the share had soared to 96 per cent.

The UK discovered the strain due to prolific genomic sequencing of the coronavirus.

It is eighth in a list of the world’s top sequencers, led by countries with much smaller caseloads.

The UK has analysed 7.4 per cent of its two million-plus cases –157,439 cases – according to the Covid-19 Genomics UK Consortium.

Experts have said other countries need to catch up.

The National explains why.

Sars-CoV-2 virus, yellow, which caused the Covid-19 pandemic, is seen emerging from the surface of cells, rendered in blue and pink.

What is the benefit of sequencing the genome of coronavirus cases?

There are several.

All viruses change and by tracing mutations over time scientists can work out their impact.

Sequencing traces these changes, mapping the lineage, transmission and the rate of evolution of the virus, stated a report by McKinsey & Company.

“In the case of New York City’s initial outbreak in March 2020, once epidemiologists identified the probable date of introduction and the strain, public health leaders were able to estimate how many people in the area were infected.

“Such information is vital to support effective response,” it said.

In the UK, research has since confirmed what scientists already suspected – the B117 strain discovered in the UK is significantly more transmissible.

But by discovering the presence of the new variant, the government was able to quickly contain it by imposing another strict lockdown, which eventually brought the growth in new cases under control.

How many strains are there of SARS-CoV-2?

There are several known strains, and they will continue to emerge over time.

The virus acquires about two mutations per month. Most of them are useless to SARS-CoV-2, but they sometimes assist the virus by enabling it to spread more easily, for example.

A few of the strains emerging include the same mutations, which is a sign they benefit the virus in some way.

For example, a number now share the E484K mutation in the spike protein, dubbed “eek” by some scientists.

The mutation is known to reduce the protection offered by vaccines and previous infection by “substantially” increasing the amount of serum antibody needed to prevent the infection of cells, according to research by the University of Cambridge.

It was first identified in a variant that appeared in South Africa.

But it has since been detected in the P1 Brazilian strain, which is responsible for a second massive surge in the rainforest city of Manaus, along with some Kent variant samples.

Last week, it was revealed 70 per cent of Covid-19 patients tested at a hospital in Tokyo also carried the E484K mutation.

How many countries sequence cases?

More don’t than do.

Australia is the world’s top sequencer. It tests more than half of samples, according to the GISAID Initiative, which provides a global database of coronavirus genomes. But the country has recorded a relatively small number in total, because it has not had many Covid-19 cases.

The UK is by far the biggest sequencer, testing about 8 per cent of samples from its considerable caseload. That represents 45 per cent of the world’s sequences, according to McKinsey & Company.

Some countries, such as the US, sequence less than half a per cent of cases. And many have no sequencing capacity at all.

According to research, mutations can reduce the protection offered by vaccines and previous infection by ‘substantially’ increasing the amount of serum antibodies needed to prevent the infection of cells. Reuters

Does the UAE sequence samples?

Yes. The country has not revealed what percentage of samples it sequences, but Dr Farida Al Hosani, a federal health spokeswoman, said the mutations circulating in the Emirates are monitored.

“Since the beginning of the global announcement of new strains, the UAE has been following up on changes and developments in the virus, and a national team was formed to study the tracking of mutated strains in co-operation with all health authorities,” she said.

“The team analyses the situation periodically and reviews recommendations in this regard.”

G42 Healthcare, a subsidiary of Abu Dhabi-based Group 42, said it has conducted a SARS-CoV-2 genome sequencing study that identified the genomic source of the pandemic.

The viral genome sequencing was performed on 1,067 nasopharyngeal swab samples collected in Abu Dhabi between May and June 2020.

The analysis revealed unique genetic variations specific to the UAE virus strains, and the patterns of the virus’s introduction, the company said.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.

Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.

Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.

Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.

“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.

Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.

From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.

Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.

BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.

Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.

Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.

“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.

Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.

“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.

“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”

The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

What is blockchain?

Blockchain is a form of distributed ledger technology, a digital system in which data is recorded across multiple places at the same time. Unlike traditional databases, DLTs have no central administrator or centralised data storage. They are transparent because the data is visible and, because they are automatically replicated and impossible to be tampered with, they are secure.

The main difference between blockchain and other forms of DLT is the way data is stored as ‘blocks’ – new transactions are added to the existing ‘chain’ of past transactions, hence the name ‘blockchain’. It is impossible to delete or modify information on the chain due to the replication of blocks across various locations.

Blockchain is mostly associated with cryptocurrency Bitcoin. Due to the inability to tamper with transactions, advocates say this makes the currency more secure and safer than traditional systems. It is maintained by a network of people referred to as ‘miners’, who receive rewards for solving complex mathematical equations that enable transactions to go through.

However, one of the major problems that has come to light has been the presence of illicit material buried in the Bitcoin blockchain, linking it to the dark web.

Other blockchain platforms can offer things like smart contracts, which are automatically implemented when specific conditions from all interested parties are reached, cutting the time involved and the risk of mistakes. Another use could be storing medical records, as patients can be confident their information cannot be changed. The technology can also be used in supply chains, voting and has the potential to used for storing property records.
