 Covid-19 WHO wants an investigation into the hypothesis of a leak from a Chinese laboratory               

WHO wants an investigation into the hypothesis of a leak from a Chinese laboratory most likely hypothesis The Covid-19 transmitted by an intermediate animal, according to the WHO As WHO experts publish their report on the origin of the Covid-19, the director of the institution denounced the lack of access of the experts sent on mission to China to raw data. He recommends further investigation into the hypothesis of a virus leak from a Chinese laboratory The joint study by WHO and Chinese experts concluded that transmission to humans through an intermediate animal was a probable hypothesis at very high probable, while a laboratory incident remains extremely unlikely. The origin of Covid-19 is still hypothetical after the passage of a WHO team in China. The joint study by experts from the UN and Chinese agency concluded that transmission of the virus to humans by an intermediate animal was "likely to very likely". On the other hand, the laboratory incident that could have caused the spread of SARS-CoV-2 is extremely unlikely, according to the same team. The specialists, in the final version of the report, which AFP obtained a copy of, did not have enough leeway, according to some, to work freely during their four-week stay in China. They held that "given the literature on the role of animal husbandry as intermediate hosts for emerging diseases, it is necessary to carry out other investigations including greater geographic scope in China and elsewhere.

This The report confirms the first conclusions of the experts that they presented on February 9 in Wuhan where the virus appeared. Experts favor the generally accepted theory of the natural transmission of the virus from a reservoir animal - probably the bat - to the human, via another animal that has not yet been identified.

Direct transmission of the virus via the reservoir animal is, however, considered possible to probable, by the report. Experts have also not ruled out that of transmission by frozen meat - a path favored by Beijing - judging that this scenario was possible.

The report recommends continuing studies on the basis of these three hypotheses, but it sweeps aside on the other hand, the possibility that the virus was transmitted to humans due to a laboratory accident. The administration of former US President Donald Trump accused the Wuhan Institute of Virology, which conducts research on very dangerous pathogens, of having let the coronavirus escape, voluntarily or not. In their report, the experts indicate that they have not studied the case of a voluntary leak, and consider an accident extremely unlikely. And in the midst of this controversy, the boss of the WHO called for a new investigation on Tuesday, March 30, with specialized experts on the hypothesis of a leak of the virus that caused the Covid-19 pandemic from a laboratory in Wuhan . He criticized the lack of access to raw data by international experts during their mission to China earlier this year. Although experts, who investigated the origin of the virus in China in January and February, considered the hypothesis of a laboratory leak to be the least likely, "it requires more investigation, probably with new missions with specialized experts that I am ready to deploy, assured Tedros Adhanom Ghebreyesus during the briefing he gave to member countries on the report officially published on Tuesday.

This hypothesis that the Sars-Cov-2 virus could have escaped from a laboratory has been strongly defended by the US administration under the chairmanship of Donald Trump, based on information from its intelligence services. But China has always denied this possibility.

the difficulties of access to data Chinese Dr Tedros was speaking just before the press conference of some of the international experts who went to China in January 2021 to conduct the investigation more than a year after the start of the pandemic in the metropolis of Wuhan in December 2019.

He also pointed out that international experts "had expressed their difficulty in accessing raw data" during their stay in China. A rare public criticism of how Beijing handled this joint investigation. 

The head of the delegation of international experts, Peter Ben Embarek, played down the matter at a press conference, saying that in China as elsewhere, some data could not be shared for reasons of respect for privacy.

This report is a very important start, but it is not the last word, underlined the director general of the WHO.
