The discovery of suspicious samples of corona may change the theory of the origin of the virus

Since the early stages of the coronavirus pandemic, conspiracy theories have been circulating about the origin of the virus, and whether it was deliberately manufactured or if it got out of control during scientific research and accidentally leaked.

From time to time, some research appears Possibilities and theories that may be wrong or right about the origin of the virusHowever, this does not change anything that the emerging virus has killed millions of people around the world.

And recently, a preliminary version of a study published in The Lancet, on August 6, 2021, headed by Elisabetta Tanzi, a professor in the Department of Biomedical Sciences for Health at the University of Milan in Italy, reported that she and her colleagues had made a potentially huge discovery, while researchers were studying the samples. collected as part of the measles and rubella surveillance in Italy, Asharq Al-Awsat newspaper reported.

Does the virus originate in China?

Does the virus originate in China?

Italy or China?

Scientists reported the discovery of evidence of genetic material for the “SARS-Cove-2” virus in samples from 11 people that were taken before the epidemic was announced, as the first case dates back to the late summer of 2019, and this means that the virus was spreading in Italy much earlier than that day. December 8, which is believed to be the date of the first known case in the Chinese city of Wuhan.

These findings are potentially a game-changer, and may alter our understanding of how the COVID-19 pandemic emerged, how it spreads, and how the virus itself works.

This is not the first study to assume that “Covid-19 was spreading in Italy long before it was reported in Wuhan. These studies were pushed by state media and authorities in China as possible evidence that the epidemic may never have originated in Wuhan.”

But the timeline given by the Italian authors also raises big questions when they built a tree for the mutation of the virus. This tree indicates that the outbreak of the virus in Wuhan occurred before moving to Italy in October 2019, meaning that the researchers argue that the virus came from Wuhan to Italy during the summer of 2019, “which fits with whatever we were seeing at the time, as Andrew Rambaut, a molecular evolutionary biologist at the University of Edinburgh in the United Kingdom, says in his paper published in July 2021 in the specialized scientific journal Genome Biology.

While Zeng Guang, a former chief epidemiologist at the Chinese Center for Disease Control and Prevention, claimed at an academic conference in November 2020 that “Wuhan was the place where the coronavirus was first discovered, but it was not where it originated,” Liang emphasized. Wanyan, head of the Chinese side of the World Health Organization team, which is tracing the origins of the epidemic, said that the next stage of the investigation should be conducted in other parts of the world, as transmission of the virus was identified as occurring before its discovery in Wuhan, which is similar to another narrative pushed by the Chinese authorities in Earlier, the virus may have been brought to China on canned frozen food.

However, Jesse Bloom, a viral evolutionary geneticist at the Fred Hutchinson Cancer Research Center in Seattle, Washington, USA, says that “there is compelling evidence that the Covid-19 pandemic originated in China, almost certainly in Wuhan.” Chinese media to say that the epidemic may have originated elsewhere in the world is scientifically misleading.

Millions of people die around the world

The Corona virus has caused the death of at least 4,683,586 people in the world since the World Health Organization office in China reported the emergence of the disease at the end of December 2019.

The United States is the country most affected in terms of deaths, followed by Brazil, India, Mexico and Peru.

The World Health Organization, taking into account the excess mortality rate directly or indirectly related to Covid-19, considers that the outcome of the epidemic may be two or three times greater than the officially announced outcome.
