Critics accuse WHO for relying too much on politically compromised Chinese fieldwork and data.

Despite a high-profile visit to China by a team of international experts in January, the world is no closer to knowing the origins of Covid-19, according to one of the authors of an open letter calling for a new investigation into the worldwide pandemic.

"At this point, we are no further advanced than we were a year ago," said Nikolai Petrovsky, an expert in vaccines at Flinders University in Adelaide, Australia, and one of 26 global experts who signed the open letter, which was published on Thursday.

In January this year, a team of scientists picked by the World Health Organization (WHO) visited hospitals and research institutes in Wuhan, the central Chinese city where the coronavirus was identified, in search of clues about the origins of Covid-19.

But the mission has come under fire, with critics accusing the WHO of relying too much on politically compromised Chinese fieldwork and data.

Team members also said China was reluctant to share vital data that could show Covid-19 was circulating months earlier than it was first recognized.

The open letter said the WHO mission "did not have the mandate, the independence, or the necessary access to carry out a full and unrestricted investigation" into all theories about the origins of Covid-19.

"All possibilities remain on the table and I have yet to see a single piece of independent scientific data that rules out any of them," said Petrovsky.

At a press briefing to mark the end of the WHO visit Wuhan, mission head Peter Ben Embarek appeared to rule out the possibility that the virus was exposed from a laboratory in Wuhan.

But Petrovsky said it "doesn't make any sense" to rule any possibility out, and said the aim of the open letter was "to get an acknowledgment globally that no one has yet identified the source of the virus and we need to keep searching."

"We need an open mind and if we close down some avenues because they are considered too sensitive, that is not how science operates," he added.
