WHO chief criticises China after 'raw data' was withheld from team investigating virus origins

WHO investigators who travelled to China to research the origins of COVID-19 were not allowed to access some raw data, Tedros Adhanom Ghebreyesus says.

Data was withheld from World Health Organisation investigators who travelled to China to research the origins of the coronavirus epidemic, WHO Director-General Tedros Adhanom Ghebreyesus says.

Australia and 13 other countries immediately called for China to give "full access" to independent experts to all data about the original outbreak in late 2019.

In its final report, 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 a lab leak was "extremely unlikely" as a cause.
One of the team's investigators has already said China refused to give raw data on early COVID-19 cases to the WHO-led team, potentially complicating efforts to understand how the global pandemic began.

"In my discussions with the team, they expressed the difficulties they encountered in accessing raw data," Dr Tedros said.

"I expect future collaborative studies to include more timely and comprehensive data sharing."
The inability of the WHO mission to conclude yet where or how the virus began spreading in people means that tensions will continue over how the pandemic started - and whether China has helped efforts to find out or, as the United States has alleged, hindered them.

"The international expert study on the source of the SARS-CoV-2 virus was significantly delayed and lacked access to complete, original data and samples," Australia, Canada, the Czech Republic, Denmark, Estonia, Israel, Japan, Latvia, Lithuania, Norway, South Korea, Slovenia, the UK, the US and the European Union said in a joint statement.

Although the team concluded that a leak from a Wuhan laboratory was the least likely hypothesis for the virus that causes COVID-19, Dr Tedros said the issue required further investigation, potentially with more missions to China.

"I do not believe that this assessment was extensive enough," he told member states in remarks released by the WHO.

"Further data and studies will be needed to reach more robust conclusions."

The WHO team's leader, Peter Ben Embarek, told a press briefing it was "perfectly possible" the virus had been circulating in November or October 2019 around Wuhan, and so potentially spreading abroad earlier than documented so far.

"We got access to quite a lot of data in many different areas but of course there were areas where we had difficulties getting down to the raw data and there are many good reasons for that," he said, citing privacy laws and other restrictions.

Second phase studies were required, Dr Embarek added.

He said the team had felt political pressure, including from outside China, but that he had never been pressed to remove anything from its final report.

Dominic Dwyer, an Australian expert on the mission, said he was satisfied there was "no obvious evidence" of a problem at the Wuhan Institute of Virology.

The European Union called the study "an important first step" but renewed criticisms that the origin study had begun too late, that experts had been kept out of China for too long and that access to data and early samples had fallen short.

In a statement, Walter Stevens, EU ambassador to the United Nations in Geneva, called for further study with "timely access to relevant locations and to all relevant human, animal and environmental data available".
