Scientist says early coronavirus samples were deleted from NIH database | CNN
Scientists investigating the origins of the Covid-19 pandemic might be working with the wrong samples, because some early samples of the virus submitted by a Chinese researcher were deleted from a shared database, an expert in the evolution of viruses says.
"This study does not provide any additional strong evidence favoring either natural zoonosis or lab accident. Rather, it shows that there are additional sequences from relatively early in the outbreak that are still unknown, and in some cases have mutations that suggest they are probably evolutionarily older than the viruses from the Huanan Seafood Market," Bloom said in an email to CNN.
