He China Center for Disease Control has produced a new report about his research on the origin of the pandemic of SARS-CoV-2. “Surveillance of SARS-CoV-2 in the environment and animal samples of the Huanan Seafood Market” presents virus detection results from 1,380 samples collected from the environment and from market animals in early 2020.
Ensures that noor it can be ruled out that the Wuhan market was only an amplifier of the transmission of the disease and not the origin of the pandemic. In this regard, he alludes to the fact that the virus had already been isolated on dates prior to December 2019 in other countries.
according to theanalysis and interpretation of the data published by the Chinese Center that makes Francisco José Roig Vázquez, andspecialist in Pneumology at HM Hospitales, the document “disagrees with a recent independent report that pointed to raccoon dogs as possible sources of transmission. Therefore, there is still a dispute of options between Chinese and independent sources in which the World Health Organization is trying to mediate to clarify the origin of the disease.
The report remember that the market of wuhan It has more than 50,000 square meters with 678 stalls, of which 1.5% sold wild animals. According to the Chinese center, the most affected by the virus It was the southwestern zone and the northeastern zone, but no contamination was found in 18 types of animals studied and, on the other hand, in a very abundant way, in samples of wastewater from the sewers.
For this reason, “the document maintains –explains Roig Vázquez-that it is likely that interhuman transmission already existed during the month of December and that they were people outside the market –just 800 meters from a very busy train station- those who carried the disease, which together with the conditions of agglomeration and the large circulation of people in this place favored the transmission”.
