Scientist’s hunt for COVID-19’s origin finds early virus sequences Chinese team deleted from NIH database

In a world starved for any fresh data to help clarify the origin of the COVID-19 pandemic, a study claiming to have unearthed early sequences of SARS-CoV-2 that were deliberately hidden was bound to ignite a sizzling debate. The unreviewed paper, by evolutionary biologist Jesse Bloom of the Fred Hutchinson Cancer Research Center, asserts that a team of Chinese researchers sampled viruses from some of the earliest COVID-19 patients in Wuhan, China, posted the viral sequences to a widely used U.S. database, and then a few months later had the genetic information removed to “obscure their existence.”

To some scientists, the claims reinforce suspicions that China has something to hide about the origins of the pandemic. But critics of the preprint, posted yesterday on bioRxiv, say Bloom’s detective work is much ado about nothing, because the Chinese scientists later published the viral information in a different form, and the recovered sequences add little to what’s know about SARS-CoV-2’s origins.
