This snipped buried in the Newsweek article stood out (for me): One important piece was an extensive Medium post by the Canadian longevity entrepreneur Yuri Deigin that discussed RaTG13, a virus Shi Zhengli had revealed to the world in a February 3 paper in the journal Nature. In that paper, Shi presented the first extensive analysis of SARS-CoV-2, which had seemed to come from nowhere—the virus was unlike any that had been seen before, including the first SARS, which had killed 774 people from 2002 to 2004. In her paper, however, Shi also introduced RaTG13, a virus that is similar in genetic makeup to SARS-CoV-2, making it the only known close relative at the time. The paper was vague about where RaTG13 had come from. It didn't say exactly where or when RaTG13 had been found, just that it had previously been detected in a bat in Yunnan Province, in southern China. The paper aroused Deigin's suspicions. He wondered if SARS-CoV-2 might have emerged through some genetic mixing and matching from a lab working with RaTG13 or related viruses. His post was cogent and comprehensive. The Seeker posted Deigin's theory on Reddit, which promptly suspended his account permanently.
