More than 10 experts from the World Health Organization expert group published a joint signed article in the British Journal of Nature published on the 26th. -19 virus "laboratory leak theory" data, and submitted it to the WHO. But so far, there is no".
At the beginning of this year, 17 Chinese experts and 17 foreign experts formed a joint expert group to carry out a 28-day global traceability study in Wuhan. The joint research report was officially released in March. The conclusions included the belief that the COVID-19 virus It is "very unlikely" to introduce humans through laboratories, to investigate potential early transmission in other countries "is important", etc., and to put forward specific recommendations for future traceability work.
The jointly signed article pointed out that before the publication of the joint research report, some governments had put pressure on the WHO, saying that “China did not fully share data” and “not enough attention was paid to the'laboratory leak theory'”.
When reviewing the work of the expert team in China, the article said that they interviewed clinical, laboratory, and public health professionals and visited institutions involved in the early response and follow-up investigation of the epidemic. The research work has received support from many sources. “The Chinese team has undertaken a large amount of preparation work (for the joint research report), including more than 1,000 professionals who are responsible for collecting, analyzing, presenting and discussing data and research results during the joint mission.”
The article emphasized that the Chinese team shared a lot of new information. "In this mission, the scientific discussions between the international expert group and the Chinese team were very active and a lot of information was exchanged." The two parties had a lot of discussions on necessary further work and continuous data sharing. Since the release of the joint research report, the WHO expert group has also continued to cooperate with the Chinese expert group.
When talking about the "laboratory leak theory," the article said that this did not belong to the original mission of the WHO expert group. But despite this, the expert group still "conducted candid discussions with key scientists from relevant institutions in Wuhan", "but found no evidence that can be followed up."
For some time, some media have equated the "laboratory leak theory" with the possibility that the COVID-19 virus can be introduced into humans via an animal (intermediate) host. But the article emphasizes, "We believe that the existing data does not support this view."
The article emphasizes that the tracing of the COVID-19 virus is a science-based global priority and is currently in a critical period, because the time window for conducting some key scientific researches on the tracing is closing on a global scale. The article lists the priorities for future virus traceability research, including finding earlier cases of COVID-19 in all regions of the world.
