The coronavirus crisis questions, sometimes arouses fantasies, and the mystery remains unsolved more than a year later.

Although experts, who investigated the origin of the virus in January and February in China, considered the hypothesis of a laboratory leak to be the least likely, "It requires further investigation, probably with new missions with specialized experts that I am ready to deploy, ”assured Tedros Adhanom Ghebreyesus during the briefing he gave to member countries on the report officially published on Tuesday.
The cat and the rabbit are also on the suspect list
Its authors judge the transmission of the virus to humans by an intermediate animal "probable to very probable", while the hypothesis of a laboratory incident is on the contrary qualified as "extremely improbable".
The study favors the generally accepted theory of the natural transmission of the virus from a reservoir animal (probably the bat) to humans, through another animal not yet identified.
Among the suspects are the domestic cat, rabbit or mink, or the pangolin or badger-ferret.
However, direct transmission of the virus via the reservoir animal is considered “possible to probable” by experts.
They also do not rule out the hypothesis of transmission by frozen meat - a path favored by Beijing -, deeming this scenario "possible".
The report recommends continuing studies on the basis of these three hypotheses, but however brushes aside the possibility of transmission to humans during a laboratory accident.
A theory that Professor Etienne Decroly, virologist at the CNRS, called to examine last November in our columns.
