chiede di fare approfondimenti sui dati relativi alle origini del Covid.
"In May 2020, the World Health Assembly requested that the World Health Organization (WHO) director-general work closely with partners to determine the origins of SARS-CoV-2 (2). In November, the Terms of Reference for a China–WHO joint study were released (3). The information, data, and samples for the study's first phase were collected and summarized by the Chinese half of the team; the rest of the team built on this analysis.
Although there were no findings in clear support of either a natural spillover or a lab accident, the team assessed a zoonotic spillover from an intermediate host as “likely to very likely,” and a laboratory incident as “extremely unlikely” [(4), p. 9]. Furthermore, the two theories were not given balanced consideration. Only 4 of the 313 pages of the report and its annexes addressed the possibility of a laboratory accident (4). Notably, WHO Director-General Tedros Ghebreyesus commented that the report's consideration of evidence supporting a laboratory accident was insufficient and offered to provide additional resources to fully evaluate the possibility (5).
"
In pratica si e' data "Molto probabile" l'ipotesi di spillover da specie intermedia ed "estremamente improbabile" l'ipotesi di incidente di laboratorio, ma Senza prove definitive,
ne' a favore ne contrarie alle due ipotesi.
Direi che almeno emerge in modo plateale che la "comunita' scientifica" non e' poi cosi' coesa nell'aver ben chiaro cosa sia successo,
almeno questi 18 non sono cosi' certi:
