“I don’t see any motivation, but I don’t think they are independent of each other,” Rambaut said. “Because once the idea is confirmed, people will look at the samples they have stored to see what they can find.”
Other studies that reported earlier detection of the virus in Italy have similar flaws. A study Published by the Ministry of Environment and Health in Rome in August 2020, it reported that Sars-CoV-2 RNA was detected in sewage samples collected in Milan and Turin on December 18, 2019. These findings aroused the suspicion of Alex Crits-Christoph, a postdoctoral fellow at Johns Hopkins University who specializes in genetic data bioinformatics research. The researchers conducted three different tests, but only one was positive. They also designed their own primers to target specific regions of RNA, although at the time standardized primers for Sars-CoV-2 were being used all over the world. “It makes me feel a little strange,” he said.

Researchers looked at the antibodies of volunteers recruited from all regions of Italy to participate in the lung cancer screening test and found that as early as September 2019, more than one hundred participants had developed antibodies to the coronavirus. “Our results show that the spread of Sars-CoV-2 in Italy was earlier than the first official Covid-19 case was diagnosed in Lombardy, even before the first official report by the Chinese authorities, which was Covid-19. The occurrence and spread of the pandemic provide new clues,” the author wrote.them Theorizing exist Interview They may have detected a strain that is “not easy to spread” that can spread without causing a major outbreak.The paper is widely cover go through English conversation mediaBut others pointed out the main flaws of this paper. The researchers did not take the necessary measures to prevent the detection of antibodies to other coronaviruses, such as the common cold. “Any antibody test has false positives, so when you screen a group of individuals with a very low prevalence, most of the positive results are false,” said Marion Koopmans, a virologist at Erasmus Medical Center. , He is a WHO team that went to Wuhan to investigate the start of the coronavirus pandemic.The study is Announce investigation The magazine published a comment in March 2021, but never made any corrections. WHO requires retesting of samples in other laboratories.this survey discover Not a sample Contains high enough levels of antibodies to be considered evidence of infection.
other Learn A 25-year-old woman living in Milan had a skin biopsy when she came to the hospital with a rash on November 10. A few months later, after careful examination, the lead researcher and dermatologist Raffaele Gianotti who was in charge of treating her found evidence of Sars-CoV-2 molecules in her skin samples.WHO wants to investigate the case, but now No one can find a female patient, And Gianotti died in March. (The rest of the authors of the paper say that there is no update on the case.)
Rambaut said these findings were “used by various parties to support a specific set of narratives.” In particular, they have cover frequently go through Chinese official media relayed the research, showing that China is not the country of origin of the virus. “Wuhan is the place where the coronavirus was first discovered, but not where it originated,” Said Zeng Guang, the former chief epidemiologist of the Chinese Center for Disease Control and Prevention, at an academic conference in November 2020.
