Examine: The Omicron variant of COVID-19 could also be masking itself as a standard chilly virus

Might the Omicron variant of COVID-19 be masking itself as a standard chilly virus?

The Omicron variant of the virus that causes COVID-19 seemingly acquired a minimum of considered one of its mutations by selecting up a snippet of genetic materials from one other virus – presumably one which causes the widespread chilly.

Researchers say that this explicit genetic sequence doesn’t seem in any earlier variations of the coronavirus, referred to as SARS-CoV-2, however is seen in lots of different viruses together with people who trigger the widespread chilly.

By inserting this explicit snippet into itself, Omicron is perhaps making itself look “extra human,” which might assist it evade assault by the human immune system, stated Venky Soundararajan of Cambridge, Massachusetts-based knowledge analytics agency nference, who led the research.

The research, “Omicron variant of SARS-CoV-2 harbors a singular insertion mutation of putative viral or human genomic origin,” was printed December 2, 2021, on OSFPreprints.

Ought to this show to be true, it may imply the virus transmits extra simply, whereas solely inflicting gentle or asymptomatic illness, CTV Information Canada is reporting.

At this cut-off date, there may be a lot that scientists have no idea in regards to the Omicron variant, like does it trigger extra critical illness, or is it extra infectious? It will take a number of weeks to get solutions to those and different questions.

A glance into the research

Cells within the lungs and within the gastrointestinal system can harbor each SARS-CoV-2 and common-cold coronaviruses concurrently, primarily based on earlier research. This in itself, can arrange the scene for viral recombination.

It is a course of during which two completely different viruses in the identical host cell work together whereas making copies of themselves, producing new copies which have some genetic materials from each “mother and father.”

This new mutation may have first occurred in an individual contaminated with each pathogens when a model of SARS-CoV-2 picked up the genetic sequence from the opposite virus, Soundararajan and colleagues stated within the research, which has not but been peer-reviewed.

This genetic sequence seems very often within the coronaviruses that trigger colds in folks – often called HCoV-229E – and within the human immunodeficiency virus (HIV) that causes AIDS.

South Africa, the place Omicron was first recognized, has the world’s highest fee of HIV, which weakens the immune system and will increase an individual’s vulnerability to infections with common-cold viruses and different pathogens. 

It’s fairly attainable that in that a part of the world, there may have been many instances of recombination that added this ubiquitous set of genes to Omicron, Soundararajan stated.

“We most likely missed many generations of recombinations that occurred over time and that led to the emergence of Omicron,” Soundararajan added.

Soundararajan additionally provides that it’s all the extra vital that individuals are getting the at present out there COVID-19 vaccines.

“You need to vaccinate to cut back the percentages that different folks, who’re immunocompromised, will encounter the SARS-CoV-2 virus,” Soundararajan stated.
