The debate over the origin of the COVID-19 pandemic remains unresolved years later.
Among the most recent investigations, a new work from the University of New South Wales (Australia) published in the journal ‘Risk Analysis’ stands out, in which new evidence is collected about the origin of the SARS-CoV-2 virus.
The origin of COVID-19, however, has been highly debated: most studies have focused on a zoonotic origin, but this new research examined the probability of a non-natural origin, that is, from a laboratory.
The results indicate a greater probability of a non-natural origin of the virus.
To reach this conclusion, researchers, including Xin Chen, used an established risk analysis tool for differentiating natural and unnatural epidemics, the modified Grunow-Finke assessment tool (mGFT), to study the origin of COVID-19. 19.
However, researchers say this risk assessment cannot prove the specific origin of the COVID-19but shows that the possibility of a laboratory origin cannot be easily ruled out.
They created a laboratory in the city where it originated
About four years have passed since the first case of infection with a new coronavirus (CoV) (SARS-CoV-2) in the city of Wuhan, China.
In this same city, the Institute of Virology that bears the name of the city was founded in 1956 and in 2015 the first laboratory of virology opened in this center. biosecurity level 4 of the Asian country.
For many, it was no coincidence that Wuhan was the city with the first cases of infection recorded in the world and at the same time the headquarters of the virology institute.
