Omicron Origins Are Called Into Question by a New Study

Last year, Southern Africa was where the Omicron variety was first discovered. A recent study that reveals the strain progressively arose over several months in numerous places across Africa has cast doubt on the origins of the Omicron variation.

According to many scientists, Omicron developed its mutations after residing in an immune-compromised person who was unable to eradicate the illness.

Others have proposed that the variation first infected animals, where it underwent a dramatic evolution, before returning to humans.

Now, researchers from South Africa, where the variant was initially discovered, have discovered that Omicron’s genetic forebears existed on the continent of Africa months before the strain became well-known, showing that it gradually evolved over time through common transmission mechanisms.

Dr. Tongai Maponga, a virologist at Stellenbosch University who assisted in the research’s direction, said: “This crucial work throws insight on the topic of when, when, and how the dominating Omicron variation originated The somewhat unexpected outcomes help us better understand the unique virus and offer helpful advice on how to react and not react to similar circumstances in the future.”

The Omicron version was first discovered in a patient in South Africa in the middle of November 2021, and it quickly spread to 87 nations.

It had supplanted Delta by the end of the week to take the top spot among Covid variants worldwide. The virus’s wide variety of mutations, many of which had never been observed before, enabled it to get past the immune system’s defenses and spread quickly across people.

A PCR test for the precise detection of Omicron was developed by researchers at Stellenbosch University’s Division of Medical Virology. More than 13,000 respiratory samples taken from Covid patients between the middle of 2021 and the beginning of 2022 in 22 African nations were tested using it.

With the aid of these tests, the specialists were able to determine when and how quickly the Omicron variety propagated. In addition, the research team analyzed the genetic composition of 670 of these samples, which showed that Omicron-specific mutations were present in 25 persons from six different African nations in August and September 2021, two months before the variant’s ultimate form arose.

Many of the viruses discovered by the retrospective study resembled Omicron to varying degrees, but they differed from it, indicating that they were the variant’s earliest viral relatives. The researchers came to the conclusion that Omicron originated in Africa but may have spread outside of the two countries where the initial instances were found, South Africa and Botswana.

They continued by saying that their research raised more concerns about the decision made by several Western nations to impose a travel restriction on South Africa, which resulted in an estimated loss to the country’s economy of $600 million.
