CHINA UPDATES COVID-ORIGIN STUDY — Researchers from the Chinese Center for Disease Control and Prevention published an updated report in Nature on Wednesday about the animals sold at the Huanan Seafood Market in Wuhan at the beginning of the pandemic, leading to more controversy among scientists about what the data means, Carmen reports. In a nutshell: The researchers wrote that existing evidence is insufficient to conclude that raccoon dogs sold at the market were the intermediate host animal for the virus or the virus spilled over from animals to people at the market, as an international study suggested last year. China CDC researchers said they didn’t identify any animal infected with the virus among their samples. And even if that were the case, it’s possible that people infected the animals instead of the other way around. What this means: We’re still not sure whether the pandemic started in the Wuhan market, where many wild animals were sold. Why this study created controversy: The raw data underpinning this study was published recently on the international virus database GISAID, leading a group of mostly Western scientists to release an analysis linking raccoon dogs with the virus’ emergence. GISAID briefly revoked the scientists’ access to the database, claiming they had broken the rules of use by publishing their analysis before the Chinese scientists had the chance to do so. Now, the Western scientists accuse the Chinese scientists of misinterpreting data, such as identifying animals like pandas not sold at the Huanan market and confusing dogs with raccoon dogs. They also said the methods Chinese experts used to analyze the data aren’t reproducible and their conclusions are flawed. Why it matters: This debate adds to the confusion about how the pandemic started — reminder: we don’t know — and may embolden other experts and U.S. lawmakers who believe the virus most likely spilled over from a virology lab in Wuhan to continue emphasizing that theory. IT’S OVER? Germany’s health minister, Karl Lauterbach, announced Wednesday that the pandemic is over in his country, POLITICO’s Gabriel Rinaldi reports. After reviewing data on variants, vaccination rates and hospital cases, Lauterbach said he made the assessment that Germany had “successfully overcome the pandemic.” The epidemiologist was known for cautious Covid policies early in the pandemic, but his tone has changed recently. On Tuesday, the government’s Covid-19 expert council met for the last time. After Friday, all protective government measures against the pandemic will come to an end, including remaining mask requirements such as those for hospital visitors. The U.S. is headed in a similar direction, with many pandemic-era policies scheduled to end next month.
