China pushes back at WHO criticism over delayed Wuhan Covid data

Beijing urged World Health Organization officials not to be used as political tools after fresh accusations that Beijing delayed releasing key early data on Covid-19 considered by some scientists to be instrumental to understanding the virus's genesis.

China shared all material that it had gathered on Covid's origin when it conducted a joint mission with experts organised by the WHO in 2020 and early 2021 and has not withheld data on any cases, samples or testing results, Shen Hongbing, director of the Chinese Center for Disease Control and Prevention, said at a briefing in Beijing on Saturday.

Recent remarks by some WHO officials that dismissed the joint mission's effort were "a crude offense to the scientists around the world who participated in the initial-origin tracing work," he said


"We urge certain people at the WHO to come back to the position of science and impartiality, instead of becoming a tool for politicizing Covid's origin by some country, whether voluntarily or forced," Shen said.

Shen's remarks come days after the WHO's Covid-19 technical lead Maria D. Van Kerkhove said in an editorial that the sharing of some viral samples from a food market in Wuhan three years after they were collected amounted to a lack of data disclosure that was "inexcusable." She said the WHO-China joint mission early in the pandemic was heavily criticised for the lack of access to raw data on early cases in China, which still hasn't been granted.

At the heart of the spat among officials between the WHO and China is a new set of data on specimens collected three years ago at the market in Wuhan that Chinese researchers uploaded to the global genomic database GISAID earlier this year. The data was uploaded to aid peer review of a study conducted by the China CDC but it was released to the public by GISAID staff "by mistake," China CDC director Shen said at the briefing.

A group of international scientists found the data last month and their independent analysis showed evidence of the virus along with genetic material from several animals, including raccoon dogs, making it the strongest information yet backing the theory that it could have spilled over from animals to humans at the market.
