Experts estimate that the diseases have already transmitted more than 2.3 million. human lives, the main carriers are probably bats, but humans may have contracted the coronavirus from other mammals.
Although the animals are likely to carry the infection, so far “no host hosts have been identified,” Liang Wannian, leader of the team’s Chinese team, told reporters.
He added that research shows that the virus “can be transported long distances in frozen products.” This statement can be understood to support the hypothesis of virus imports into China.
The expert added that there were “no signs” that the virus had spread in the central Chinese city of Wuhan before December 2019, when the world’s first human infections were officially confirmed.

Peter Ben Embarak, the head of the WHO mission, backed the statement, saying that to date there was no evidence of “major outbreaks” in Wuhan.
Experts also said that the controversial theory that the virus causing the COVID-19 infection had spread from a single laboratory in Uhane was largely rejected.
“The laboratory incident hypothesis is an extremely unlikely explanation for the transmission of the virus to the human population,” said Ben Embarek. “They are not among the hypotheses that we will propose to test in the future.”
This mission is diplomatically sensitive, and even before it began, there was a fear that the true conclusions could be hidden. Then the United States demanded that the investigation be carried out “resolutely”, and China reiterated that it should not be “politicized.”
During the closely supervised visit, journalists generally stayed away from experts, but so far only snippets of their findings have appeared in the media and on social media.
The experts spent a month in China: two weeks in quarantine and the same amount of work.
However, more than a year after the virus emerged, the relevance of part of the visit to the stated goal of finding the source of the virus was questioned. For example, a visit by WHO mission participants to a propaganda exhibition praising China’s recovery from the pandemic raised questions.
A group of experts spent just an hour in the seafood market, from where many reports of the first diseases were received at the end of 2019.
They also appear to have stayed at the hotel for several days without leaving the city, where several Chinese officials met with them.
Still, further investigation was conducted at the Wuhan Institute of Virology, where inspectors spent nearly four hours and said they met with Chinese scientists, including Shi Zhengli, one of China’s leading coronavirus experts and deputy director of the laboratory. from Wuhan.
Former US President Donald Trump reiterated the controversial theory that the pandemic could have started with the release of the virus from the Wuhan laboratory.
Researchers working in that lab are conducting research on some of the most dangerous diseases, including a bat-like strain of coronavirus similar to COVID-19.
