The debate is reborn in France – La Nouvelle Tribune

But where does covid-19 come from? For many experts, the disease started as a result of animal-to-human transmission. For others, it could be a leak from a lab, making possible the idea that humans are behind the pandemic. A theory that circulated a lot during the first confinement, but which was quickly considered to be conspiratorial.

However, a team of French researchers has just revived the debate. From last April, the Dr. Jacques Fiorentino, a former emergency doctor, then said that the new coronavirus could not have been created by humans. According to the latter, the covid had then passed from animals to humans. The idea that the virus had escaped from a laboratory even seemed far-fetched, with the security levels of a P4-type laboratory being extremely developed.

Covid-19, from a laboratory?

However, a team of 5 researchers published a study in Medecine / Sciences. Regarding this paper, Dr. Étienne Decroly told journalists at Le Parisien that the accident thesis could not be ruled out. Indeed, the host animal of the virus has still not been discovered. The pangolin, once suspected, has since been exonerated. Only certainty, the bat is indeed involved.

The trail of human error, not ruled out

If the virus escaped from a laboratory, the disease would descend directly from a bat isolated by scientists. The virus would have been cultivated in the laboratory, on animal subjects, in order to understand how such a disease could pass from an animal model to a human subject. It would therefore be a virus, probably resulting from a series of medical research aimed at better understanding and apprehending this barrier between man and animal.
