New COVID-19 Mutations, What Does That Mean for Humanity?

Coronavirus lately acts as the operating system – it gets updated and gets better (fiercer and more infectious)

Just as the ruckus around the new strain of coronavirus detected in the UK subsided, new Covid-19 mutation was announced in Denmark, Brazil, Malaysia, and some other countries.

We will try to figure out how the “updated” versions of the virus differ from each other, how dangerous they are, and whether the rapid mutation of Covid-19 can threaten the effectiveness of vaccines already developed and launched into mass production.

Mutant virus from the UK. Name – VUI-202012/01

The World Health Organization announced the detection of a new strain of the Covid-19 virus in the UK last Sunday, December 20.

It is assumed that it may be 70% more infectious than the already familiar “version” of the coronavirus. Whether it is more deadly or not is still unknown.

Let’s go further.

Mutant virus from South Africa. Name – 501.V2

On Tuesday, December 22, another Covid-19 strain was recorded in the UK – two people who were in contact with those traveling to South Africa got infected.

A few days earlier, on December 18, South African Health Minister Zweli Mkhize on his Twitter announced the detection of a new type of SARS-CoV-2 Virus in the country. It was termed 501.V2.

According to Mkhize, the mutated coronavirus has started to prevail in the past two months. Scientists associate the second wave of the epidemic in the country with this version of virus.

According to BBC agency, this variant shares some similarities to the one that has already been detected in the UK, although they have evolved separately.

Both have a mutation – called N501Y – which is in a crucial part of the virus that it uses to infect the body’s cells.

Therefore, at the moment the ability of the new type of Covid-19 from South Africa to spread rapidly is considered its “peculiarity”, that is, it (like the one in UK) can also be more infectious.

Also, based on the words of Zweli Mkhize, with the emergence of N501Y, more young patients get hospitalized in critical condition due to coronavirus.

“Larger proportion of younger patients with no co-morbidities presenting with critical illness,” he wrote.

Mutant virus from Denmark. Name – N439K

Denmark’s Statens Serum Institute on Tuesday, December 22, announced the identification of a coronavirus mutation, which may be less sensitive to the vaccine.

“There is concern about how effective a vaccine will be against N439K. Therefore, it is relevant to keep an eye on how widespread the infection with this variant is in Denmark, and whether it has spread to particularly vulnerable groups,” says department head Tyra Grove Krause in a comment.

From 8 August to 6 December, the mutation was found in 1624 Danish samples.

No deaths have been recorded among persons infected with the mutation.

Scientists say that about 10% of all those tested in the country for infection with a confirmed diagnosis are carriers of the new variant of the virus.

“In terms of gender and age, N439K is spread in general in the same way as SARS-CoV-2 in Denmark. The hospitalization rate is lower than in the case of SARS-CoV-2,” the institute said.

The variant has nothing to do with the mink variants that have been found, or the British one that is mentioned these days, it was stated.

Mutant virus from Brazil. Name – B.1.1.28

On Wednesday, December 23, the Brazilian Globo TV channel, citing a study by the National Laboratory of Scientific Computation, announced the discovery of a new strain of coronavirus in the state of Rio de Janeiro.

Scientists say they currently have no confirmation that the new strain is more infectious or aggressive.

In the course of research on the new version of Covid-19, it turned out only that it differs from the “maternal” virus by mutations in 38 out of 180 genomes and, similarly to the “British” type, has a mutation E484K in the S-protein.

It was also determined that this type of pathogen appeared in July in Rio de Janeiro, after which its traces were found in 19 different cities of the state.

Mutant virus from Malaysia. Name – A701V

The country’s Minister of Health, Noor Hisham Abdullah, on Wednesday, December 23, announced the detection of a new strain of coronavirus in the country, named A701V. The latter was discovered as a result of examining samples from the state of Sabah.

“But we have yet to know the clinical impact of this variant, its infectivity rate or aggressiveness,” Dr Noor Hisham was cited as saying on New Straits Times.

He said the Health Ministry would continue to monitor the virus mutation and its impact in gauging the Covid-19 vaccine’s effectiveness.

Mutant virus from Nigeria. Name – P681H

Another new variant of the coronavirus have emerged in Nigeria, Africa’s top public health official announced that, as Blick reports.

John Nkengasong, head of the Africa Centres for Disease Control and Prevention, revealed the existence of the new P681H strain.

He believes that it is different to the strains recently discovered in the UK and South Africa.

Medics do not currently think the new strain in Nigeria is more infectious than previous strains, but Dr Nkengasong admitted it was too early to be sure.

“Give us some time … it’s still very early,” he said.

The alert about the apparent new variant was based on two or three genetic sequences, he said, but that and South Africa’s alert late last week were enough to prompt an emergency meeting of the Africa CDC.

It was found in two patient samples collected on August 3 and on October 9 in Nigeria’s Osun state.

WHO advises to share data

In response to news from the UK about a new strain of coronavirus, the World Health Organization said they fear new Covid-19 mutations.

According to WHO/Europe website, All viruses, including the virus that causes COVID-19, change as they circulate. These changes can lead to changes in characteristics of the virus. This is why WHO monitors changes closely, and why everyone must continue to take all actions to slow and eventually stop the spread of SARS-CoV-2.

“WHO advises all countries to increase the sequencing of SARS-CoV-2 viruses where possible, share sequence data internationally, and report if the same mutations of concern are found,” the message says.
