More than a year after the coronavirus pandemic began, the World Health Organization released a report on Tuesday laying out theories on how the virus first spread to humans — but it is already raising more questions than answers, including from the health body’s own leader.
The report, drafted by a 34-member team of Chinese scientists and international experts who led a mission to Wuhan, China, examines a series of politically contentious questions, including whether the virus might have accidentally emerged from a Chinese laboratory.
Some members of the expert team have raised concerns about China’s refusal to share raw data about early Covid-19 cases. In an unusual move, Dr. Tedros Adhanom Ghebreyesus, the W.H.O.’s director-general, acknowledged those concerns while speaking about the report on Tuesday. He said he hoped future studies would include “more timely and comprehensive data sharing.”
prepared remarks released to the news media. “Further data and studies will be needed to reach more robust conclusions.”
The experts had said that officials at the Wuhan Institute of Virology, which houses a state-of-the-art laboratory known for its research on bat coronaviruses, assured them that they were not handling any viruses that appeared to be closely related to the coronavirus that caused the recent pandemic, according to meeting notes included in the report. They also said that staff members had been trained in security protocols.
