The Financial Times reports that President Biden’s chief medical adviser, Dr Anthony Fauci, has called on China to release the medical records of nine people whose illnesses might provide vital clues into whether Covid-19 first emerged as the result of a lab leak. He told the FT that the records could help resolve the debate over the origins of a disease that has killed more than 3.5 million people worldwide. The records concern three researchers at the Wuhan Institute of Virology who reportedly became sick in November 2019, and six miners who fell ill after entering a bat cave in 2012.

Vanity Fair reports:

By the summer of 2020, the State Department’s COVID-19 origins investigation had gone cold. Officials in the Bureau of Arms Control, Verification, and Compliance went back to their normal work: surveilling the world for biological threats. “We weren’t looking for Wuhan,” said Thomas DiNanno. That fall, the State Department team got a tip from a foreign source: Key information was likely sitting in the U.S. intelligence community’s own files, unanalyzed. In November, that lead turned up classified information that was “absolutely arresting and shocking,” said a former State Department official. Three researchers at the Wuhan Institute of Virology, all connected with gain-of-function research on coronaviruses, had fallen ill in November 2019 and appeared to have visited the hospital with symptoms similar to COVID-19, three government officials told Vanity Fair.

While it is not clear what had sickened them, “these were not the janitors,” said the former State Department official. “They were active researchers. The dates were among the absolute most arresting part of the picture, because they are smack where they would be if this was the origin.” The reaction inside the State Department was, “Holy shit,” one former senior official recalled. “We should probably tell our bosses.” The investigation roared back to life.
