![]() We describe the seamless genetic engineering capabilities developed in the years leading up to the pandemic in VIRAL. Can scientists manipulate and genetically engineer naturally found viruses without leaving a trace? In other words, can the genome of the virus tell us its recent history? I personally think the available evidence points towards a lab origin but would not go as far as to say that there is dispositive evidence of it.ģ. The evidence does not lean so strongly towards one hypothesis or the other that we can assume one as the default truth. Please see this thread for details: Īt the moment, US intelligence, the WHO SAGO advisory group, and many top virologists and experts find both natural and lab origin hypotheses plausible and deserving of investigation. Without access to the methodology and actual data collected by investigators in Wuhan, their interpretation unfortunately falls prey to ascertainment bias. However, their analysis failed to take into account the realities in the early days of the pandemic. Some experts have asserted that there is dispositive evidence that the virus jumped from animals to people at the Wuhan Huanan market. Does the available evidence lean towards a market origin? The third is a trio of conflicting studies about whether the Huanan seafood market was the site of a natural spillover of the virus from animals to people or just the site of a human superspreader event in December 2019.Īs with the hardcover, half of our earnings from the book have gone/will go to charity.Ģ. The second is detailed information about how prominent western virologists, who had privately thought the virus was likely manipulated in a laboratory, began to instead tell the public that no lab-based scenario was plausible. The first was the discovery of a virus in a bat in Laos that is slightly more similar to SARS-CoV-2 than the virus studied at the Wuhan Institute of Virology but both are still not the progenitor of the pandemic. The updated epilogue now discusses three significant new developments since the publication of the hardback that are being hotly debated in the comments here. Yes, the updated paperback comes out in the US next week. I’m going to answer some of the questions that have come up in the comments. This is Alina Chan, one of the co-authors of Viral: The Search for the Origin of Covid-19.
