Despite a visit to China by an international team of แจ็คพอตแตกง่าย experts in January. But the world is no closer to knowing the origin of COVID-19, as the authors of the open letter call for a new investigation into the epidemic.At this point, we have not advanced more than last year," said Nikolai Petrovsky, a vaccine specialist at Flinders University in Adelaide, Australia and one of the 26 global experts who signed the letter. Unsealed, which was released Thursday.In January, a team of selected scientists from the World Health Organization (WHO) visited hospitals and research institutes in Wuhan,

a central Chinese city where the coronavirus has been identified, to look for clues about its origins. Of COVID-19But the mission came, with critics accusing the World Health Organization of relying too much on politically compromised Chinese fieldwork and data.The team members also said China was reluctant to release sensitive data that could show COVID-19 was spreading several months earlier than was first known.The open letter states that the WHO's mission "does not have the mandate, independence or access necessary to conduct full and unrestricted investigations" in all the theories on the origin of COVID-19.All the possibilities are still on the table, and I have yet to see a single independent scientific data that sets any rules," Petrovsky said.

In a news conference to mark the end of the World Health Organization's visit to Wuhan, mission leader Peter Ben Mbarek appeared to rule out the possibility of the virus leaking from a laboratory in Wuhan.But Petrovsky said it "does not make sense" to rule out any possibilities, and said the purpose of the open letter was "the purpose of the letter". "To acknowledge the world over 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 turn off certain paths because they're too sensitive, that's not the way science works," he said.
