Five years after the Covid-19 epidemics inciting the entire countries into lockdown, scientists are still trying to indicate that the virus is first trying to find coniferous evidence to infect humans.
But now that life is for a child of normal, is it the real thing where Sir -Kov -2, virus that caused Kovid, originated? What is the difference if the virus leaks from development in a laboratory or nature?
Well, researchers say that it matters: they say that it is one of the most important questions for our understanding of how pandemics begin, and we can stop them in the future.
Answer, they say, health policy, scientific penalty, public opinion on science and diplomatic relations will have a permanent impact.
The fact is not mentioned that we are still living with Kovid: World Health Organization (WHO) Kovid -19 dashboard Continues reporting hundreds of thousands of cases worldwide every month.
But from lab leak theory to zoonotic theory, and in between, the principle of conspiracy, there is no consensus on the core of Kovid.
With new investigation and analysis on this fourth anniversary, we take a look at the current thinking.
Was Sars-Cov-2 leak from a laboratory?
The new CIA director John Ratcliffe released a new assessment on 26 January, stating that the Kovid -19 “more likely to leak from a Chinese laboratory than animals.
For the lab leak theory center around the Wuhan Institute of Virology, at the institute where scientists were doing research on Koronvirus at the time of initial outbreaks in China.
“The strongest evidence comes from the research schedule [going back to] 2012. The published papers scientists of the institute show built the revised Koronwirus, “said Richard Hbright, Professor of Chemical Biology at the University of Rutgers in the US.
Research was genetically included to add spike proteins and to tested the virus’ spreading ability to test. Their declared purpose was to help prevent the outbreak of Koronwirus.
But we do not know how many Koronwirus the institute studied. “He refused to cooperate from the beginning,” said Abbreet.
Some experts say that it is possible that Wuhan Lab had Prgenitor Strains-Anecestors-Cov-2 in Sars-Cov-2, but it is impossible to prove or reject China’s alleged information on the origin of Covid. .
Then the question is how the virus would be leaked. Some people say it leaked from the accident, due to weak safety measures in the laboratory, while others suggest that it was intentionally developed and released as a biological weapon. But there is no strong proof for any principle.
“Every form of lab leak theory at Sydney University in Australia includes some types of cover ups, which is a conspiracy theory for me.”
Did Kovid -19 come from nature?
Some scientists prefer zoonotic theory: the theory that the virus developed into nature from an existing coronvirus and spread to humans in the Hyunan seafood wholesale market from wild animals, ie Wuhan, in China.
Researchers stated that they had analyzed statistical data to find out – what he said – earlier there were human matters and those cases were among market vendors who sold to living animals.
“The evidence supports a zoonotic origin,” said Angie Rasmusen, a virologist at the University of Suskechewan in Canada. “This included the expansion study of Sars-Cov-2 […] And once its evolutionary trajectory [it was in] human population.
Scientists have studied wild animals samples in Wuhan for signs of original Sars-Cov-2 virus. But they have failed to find it. And so they have failed to find out how the virus spread from the market to the external environment.
“The main step was not to trace and test animals in Huan Bazaar [at the time] And now it’s too late. For this reason, we have actually gone to identify the animal lineage, “Holmes said.
But given that Huan Market is 16 kilometers (10 mi) from the Wuhan Institute of Virology, some suggest that the lab and/or market were Epachers of Kovid.
Origin of Kovid: Tilt towards nature?
To Expert survey in February 2024 It was found that most scientists believe that Kovid emerged from nature.
Expert respondents gave an average probability of 77% to the natural, zoonotic (or zunosis) theory – four in five of the experts said it was likely to be 50% more. But experts stated that there was a 21% possibility that Kovid started due to “research-related accident”, out of which five of the five experts stated that there was 50% or more likely.
Seth Bom of the Global Catstrophic Risk Institute said, “When you keep in mind other intelligence information, the lab leak theory seems more praiseworthy,” said Seth Bom of the Global Catstrophic Risk Institute, which published the survey with nemesis insights Did.
When the bom refers to “other intelligence”, he is talking about non-scientific factors, discovering market proximity in the laboratory.
Most evidence that can provide a decisive answer, however, are lost or unavailable for public investigation.
Bome said, “Will we get evidence-based concepts on the country such as China will cooperate and upcoming with data,” Bom said.
One thing experts agreed that we need to try to solve the mystery of the origin of Kovid because it can determine how we respond to the next epidemic.
