Chinese researchers say that Wuhan is not the place where the first person-to-person transmission of SARS-CoV-2 took place.
This may have happened in India, they claim, while “blaming” other countries, including Greece.
According to research by Libing Shen (Chinese Academy of Sciences (CAS) – Institute of Neuroscience), Funan He (Fudan University, Department of Sciences) and Zhao Zhang (University of Texas, Houston, Department of Biochemistry and Molecular Biology), published on November 17 in The Lancet, “Before it spread to Wuhan, SARS-CoV-2 had already passed adaptive development during its transmission from person to person “.
“Both the geographic data of the least mutant strain and its diversity suggest that the Indian subcontinent may be the place where the first transmission occurred SARS-CoV-2 from human to human, three to four months before the outbreak in Wuhan. »
According to them, “the strain in question NC_045512 can be found in five countries and the date of its collection varies from 12/30/2019 to 4/4/2020. This result indicates that SARS-CoV-2 has very low variability.
The least mutated strain with 41 sequences found in Bangladesh, the United States, Greece, Australia, India, Italy, the Czech Republic, Russia and Serbia ”, states the investigation. “In theory, any of these points could be the birthplace of the least mutated strain.”
Elsewhere, research shows that since the first SARS-CoV-2 patient was admitted to Wuhan on December 12, 2019, hidden The transmission of SARS-CoV-2 should have started in mid to late November 2019, with an incubation period of 2 to 14 days.
With this in mind, the researchers suggest that “the first person-to-person transmission of SARS-CoV-2 could be detected earlier, in July or August 2019.”
