'WHO calls for further studies, data on origin of SARS-CoV-2 virus, reiterates that all hypotheses remain open'

'The report stems from a Member State resolution adopted by consensus at the World Health Assembly in May 2020 and calling on WHO “to identify the zoonotic source of the virus and the route of introduction to the human population, including the possible role of intermediate hosts, including through efforts such as scientific and collaborative field missions.”

“As far as WHO is concerned, all hypotheses remain on the table. This report is a very important beginning, but it is not the end. We have not yet found the source of the virus, and we must continue to follow the science and leave no stone unturned as we do,” said Dr Tedros.

The report is available on this webpage:


The report's summary concludes:

'The joint team’s assessment of likelihood of each possible pathway was as follows:

- direct zoonotic spillover is considered to be a possible-to-likely pathway;

- introduction through an intermediate host is considered to be a likely to very likely pathway;

- introduction through cold/ food chain products is considered a possible pathway;

- introduction through a laboratory incident was considered to be an extremely unlikely pathway'
