Where Did the Pandemic Start? Anywhere But Here, Chinese Scientists Argue

sciencehabit writes: From the start of the pandemic, the Chinese government -- like many foreign researchers -- has vigorously rejected the idea that SARS-CoV-2 somehow originated in the Wuhan Institute of Virology (WIV) and escaped. But over the past 2 years, it has also started to push back against what many regard as the only plausible alternative scenario: The pandemic started in China with a virus that naturally jumped from bats to an "intermediate" species and then to humans -- most likely at the Huanan Seafood Market in Wuhan. Beijing was open to the idea at first. But today it points to myriad ways SARS-CoV-2 could have arrived in Wuhan from abroad, borne by contaminated frozen food or infected foreigners -- perhaps at the Military World Games in Wuhan, in October 2019 -- or released accidentally by a U.S. military lab located more than 12,000 kilometers from Wuhan. Its goal is to avoid being blamed for the pandemic in any way, says Filippa Lentzos, a sociologist at King's College London who studies biological threats and health security. "China just doesn't want to look bad," she says. "They need to maintain an image of control and competence. And that is what goes through everything they do." The idea of a pandemic origin outside China is preposterous to many scientists, regardless of their position on whether the virus started with a lab leak or a natural jump from animals. There's simply no way SARS-CoV-2 could have come from some foreign place to Wuhan and triggered an explosive outbreak there without first racing through humans at the site of its origin. "The idea that the pandemic didn't originate in China is inconsistent with so many other things," says Jesse Bloom, a virologist at the Fred Hutchinson Cancer Research Center who has argued for more intensive studies of the WIV lab accident scenario. "When you eliminate the absurd, it's Wuhan," says virologist Gregory Towers of University College London, who leans toward a natural origin. Yet Chinese researchers have published a flurry of papers supporting their government's "anywhere-but-here" position. Multiple studies report finding no signs of SARS-CoV-2 related viruses or antibodies in bats and other wild and captive animals in China. Others offer clues that the virus hitched a ride to China on imported food or its packaging. On the flip side, Chinese researchers are not pursuing -- or at least not publishing -- obvious efforts to trace the sources of the mammals sold at the Huanan market, which could yield clues to the virus' origins.
