U.S. calls for ‘transparent’ new investigation into COVID origins

By Stephanie Nebehay

GENEVA (Reuters) – The United States called on Tuesday for international experts to be allowed to evaluate the source of the coronavirus and the “early days of the outbreak” in a second phase of an investigation into the origins of the coronavirus.

U.S. intelligence agencies are examining reports that researchers at a Chinese virology laboratory were seriously ill in 2019 a month before the first cases of COVID-19 were reported, according to U.S. government sources who cautioned on Monday that there is still no proof the disease originated at the lab.

“Phase 2 of the COVID origins study must be launched with terms of reference that are transparent, science-based, and give international experts the independence to fully assess the source of the virus and the early days of the outbreak,” U.S. health secretary Xavier Becerra said in a video message to the annual ministerial meeting of the World Health Organization.

Becerra did not mention China directly, where the first known human cases of COVID-19 emerged in the central city of Wuhan in December 2019.

The origin of the virus is hotly contested. In a report issued in March written jointly with Chinese scientists, a WHO-led team that spent four weeks in and around Wuhan in January and February said the virus had probably been transmitted from bats to humans through another animal, and that “introduction through a laboratory incident was considered to be an extremely unlikely pathway”.

A WHO spokesman, Tarik Jasarevic, asking about a follow-up mission, told Reuters on Monday that the agency was reviewing the recommendations from the report at the technical level.

“The technical teams will prepare a proposal for the next studies that will need to be carried out, and will present that to the Director-General for his consideration,” he said, referring to WHO director-general Tedros Adhanom Ghebreyesus.

Jasarevic, noting Tedros’ remarks on March 30, said that further studies would be needed in a range of areas, including on the early detection of cases and clusters, the potential roles of animal markets, transmission via the food chain and the laboratory incident hypothesis.

U.S. says hopes WHO report on virus origins is ‘based on science’

By Stephanie Nebehay

GENEVA (Reuters) – The United States expects the World Health Organization (WHO) investigation into the origins of the novel coronavirus pandemic to require further study, perhaps including a return visit to China, a senior U.S. official said on Wednesday.

Marc Cassayre, charge d’affaires at the U.S. mission to the U.N. in Geneva, also voiced hope that the WHO-led mission to the central city of Wuhan in Jan.-Feb. had access to the raw data and to the people required to make an independent assessment.

The lengthy report by the team – composed of international experts and their Chinese counterparts – is expected to be issued this week, the WHO says.

“We are hopeful that it will be based on science and be a real step forward for the world understanding the origins of the virus so we can better prepare for future pandemics,” Cassayre told a news briefing.

U.S. officials expected further work would be needed to identify the source of the SARS-CoV-2 virus, he said. “That would probably require, as we would presume, further studies of the team, maybe travel to China or further discussions.”

The probe was plagued by delays, concern over access and bickering between Beijing and Washington, which under former U.S. President Donald Trump’s administration accused China of hiding the extent of the initial outbreak.

Some team members have said China was reluctant to share vital data that could show the virus was circulating months earlier than first recognized in late 2019.

Ben Embarek, a WHO official leading the mission, said at a press briefing marking the end of the visit that the virus probably originated in bats, although it was not certain how it reached humans. He also effectively ruled out a lab leak.

WHO director-general Tedros Adhanom Ghebreyesus later said that “all hypotheses remain open” and pledged full transparency.
