Covid-19: Can new variants of the coronavirus keep emerging?

Yes, as long as the virus that caused the pandemic keeps infecting people. But that doesn’t mean new variants will keep emerging as regularly, or that they’ll be more dangerous

Indian researchers flag coronavirus mutations that could evade immune response

A forum of scientific advisers set up by the Indian government has told authorities about minor mutations in some samples of the coronavirus that could "possibly evade immune response" and require more study, a leader of the forum has told Reuters.
However, the advisers said while they were flagging the mutations, there was no reason currently to believe they were expanding or could be dangerous.

NEW DELHI :
The second surge of COVID-19 cases in India has swamped hospitals much faster than the first because mutations in the virus mean each patient is infecting many more people than before, epidemiologists and doctors say.

COVID-19: T cells from survivors, the vaccinated can recognise variants

In this study, researchers determined that SARS-CoV-2-specific CD8+ T-cell responses remained largely intact and could recognise virtually all mutations in the variants studied.
Just as vaccines were developed and were being deployed for mass inoculation, the COVID-19 virus started mutating. Today, we have many variants of this pathogen, some more lethal than others. This was expected as all viruses mutate. But the worry here was how will it affect the global fight against the pandemic? As variants of SARS-CoV-2 provoke concern that they might elude protective immune responses generated by prior infection or vaccination, researchers from the National Institute of Allergy and Infectious Diseases (NIAID) have found that a key player in the immune response remained mostly unaffected. According to them, one key player in the immune response to SARS-CoV-2 — the CD8+ T cell — remained active against the virus.

The UK variant of coronavirus is likely deadlier and more infectious than the original strain

A virologist breaks down everything you need to know about the UK variant.

New research published this week in the
British Medical Journalfound the coronavirus variant originating in the United Kingdom, called B.1.1.7, is substantially more deadly than the original strain of SARS-CoV-2.
The authors say the B.1.1.7 variant is between 32% and 104% deadlier. However, it is important to recognise these data were only collected from one group of people so more research is needed to see if these numbers hold true in other groups of patients.

Scientists discover possible new coronavirus mutation in Brazil
A possible new variant of the novel coronavirus, SARS-CoV-2, has been detected in several regions of Brazil, the Ministry of Science and Technology's National Laboratory for Scientific Computing (LNCC) said. Brazilian scientists discovered the new variant as the country's healthcare system nears collapse due to a rise in cases generated by the P.1 strain that emerged in the northern Brazil's state of Amazonas in November 2020, the Xinhua news agency reported.
A study carried out in 39 municipalities of five Brazilian states "led to the identification of a possible new variant of SARS-CoV-2 originating from variant B.1.1.33 that had circulated in Brazil," the laboratory said in a statement.

COVID-19: Intestinal blockage may be a new symptom of variants

An intestinal blockage is just that. It means something is blocking your intestines and because of this stool and food is not passing through properly.
All viruses mutate and the COVID-19 virus is no different. There are today many variants of the novel coronavirus that spurred the unprecedented global pandemic and claimed the lives of millions of people. This has experts worried because they do not know what to expect. Though, usually, mutated strains of viruses become somewhat mild as time goes by, the same may not be the case with COVID-19. The lethal UK variant is more transmissible, and the South Africa variant causes more complications and different symptoms. These variants are still being studied by scientists.
