Scientists Press Case Against the Covid Lab Leak Theory – The New York Times

In the most current volley of the debate over the origins of the coronavirus, a group of researchers this week provided a review of scientific findings that they argue reveals a natural spillover from animal to human is a far more likely cause of the pandemic than a lab incident.Among other things, the researchers point to a recent report revealing that markets in Wuhan, China, had offered live animals vulnerable to the infection, including palm civets and raccoon dogs, in the two years prior to the pandemic started. They observed the striking resemblance that Covid-19s development had to other viral illness that arose through natural spillovers, and pointed to a range of newly discovered infections in animals that are closely associated to the one that caused the new pandemic.The back and forth amongst scientists is taking place while intelligence agencies are working with an end-of-summer due date to supply President Biden with an evaluation of the origin of the pandemic. Both viruses emerged in China in the late fall, he stated, with the very first recognized cases popping up near animal markets in cities– Wuhan in the case of Covid, and Shenzen in the case of SARS.In the SARS epidemic, the new paper points out researchers eventually traced the origin to infections that infected bats far from Shenzen.Based on the distribution of infections comparable to the new coronavirus throughout Asia, Dr. Wertheim and his associates forecast the origin of SARS-CoV-2 will also be far from Wuhan.Since very first appearing in the final months of 2019, this pandemics viral culprit has yet to be found naturally occurring in any animal.In May, another team of 18 researchers released a letter arguing that the possibility of a laboratory leakage required to be taken seriously, due to the fact that there was too little proof to prefer a natural origin of the coronavirus or a leakage from a laboratory.”Basically, it truly boils down to an argument that since nearly all previous pandemics were of natural origin, this one should be as well,” said David Relman, a microbiologist at Stanford University who arranged the May letter to Science.He kept in mind that he does not object to the natural origin hypothesis as a possible explanation for the pandemic origin.
