Four theories about the origin of Corona, one of which is the most likely

Become a team of International and Chinese scientists They are about to share their joint research on the origins of the coronavirus, which caused a pandemic after it was first discovered in China more than a year ago, as four theories are being considered, one of which experts say is the most likely is.

The lengthy report comes out after months of controversy, especially between the US and Chinese governments, over how the outbreak came about as scientists continue to focus on the unsuccessful search for the origin of a microbe that has more than 2 That killed 7 million victims stifled the economy around the world.

It wasn’t immediately clear when the report would be released after it was released earlier this month.

According to many reports, the report could provide few specific answers and raise further questions.

The report is intended to provide an initial written overview of 10 international epidemiologists, data scientists, veterinarians, laboratory and food safety experts who visited China and Wuhan earlier this year – where it is believed to be the epicenter of the virus outbreak with their Chinese counterparts who collected the bulk. From early data.

Critics have questioned the team’s objectivity and insisted that the Chinese government has a decisive say in its composition. Proponents of the World Health Organization, which formed the team, say a country cannot simply be forced to do what, let alone a powerful country like China.

“I suspect this report is only a first step in investigating how the virus was created and that the WHO secretariat will likely say so,” said Matthew Kavanagh, director of the Global Health Policy and Governance Initiative at the O’Neill Institute from Georgetown University. “I expect some to criticize this as insufficient.”

She described the Wuhan trip as the first phase of a large project to find out the origin of the virus.

The World Health Organization was outraged by the portrayal of the mission as an “investigation”, saying there were attributes of forensic investigation that were not used under the resolution unanimously adopted by member states of the agency in May paving the way for collaboration be. The World Health Organization and China later relaxed the basic rules.

The four main indicators

Team member Vladimir Didkov, epidemiologist and deputy research director at the Pasteur Institute in St. Petersburg, Russia, summarized the four main indicators that were first developed about the suspected origin of the first human infection at a long press conference in China last month.

The indications were in order of likelihood: from a bat, from an intermediate animal, directly from the bats, from contaminated frozen food, from a leak from a laboratory such as the Wuhan Institute of Virology.
Chinese officials, as well as Chinese team leader Liang Wanyan, endorsed the third theory – the frozen chain of products – while President Donald Trump’s administration endorsed the fourth theory of laboratory leakage. However, Didkov said the two hypotheses are at the bottom of the list of possible sources.
He pointed out that the frozen products in which the virus was found were most likely contaminated by infected people.

It is also possible that the infected person brought the virus to the Wuhan market in connection with the outbreak and spread it to where some contaminated products were later found.
“In general, all the conditions for the spread of infection were in place in this market,” Didkov said in an interview.
“At this point in time, there are no facts to suggest a leak,” he added from the lab.
“If scientific facts suddenly appear anywhere, the priority of the novel changes accordingly. But at this moment no,” he said.
