WHO knows? We still can’t be sure of Covid’s origins

Could Covid-19 have originated from a Chinese lab accident? When the virus was first identified, many pointed out that it was close to the Wuhan Institute of Virology. It sounded like a conspiracy theory. But it’s all too plausible. And there are questions that the long-awaited report by the World Health Organisation leaves unanswered.

Only after the pandemic started did Professor Shi Zhengli, director of the Center for Emerging Infectious Diseases at the Wuhan Institute of Virology, notice that a close viral relative to Covid-19 had been found in a mineshaft years before. There was an apparent pneumonia outbreak nine years ago at a copper mine in Mojiang, around 1,000 miles from Wuhan, in an area where Zhengli’s team regularly hunted for new viruses. Six workers clearing bat excrement in this mine contracted a disease that had symptoms eerily similar to Covid-19. Four tested positive for Sars antibodies; three eventually died with a diagnosis of likely direct infection by a novel coronavirus. This, in itself, was extraordinary: it is likely it was the first ever documented case of direct human infection by a bat coronavirus.

This story is mired in oddities. Professor Zhengli confirmed a sample of the virus was at her lab in Wuhan, but claimed that the sequencing process had depleted it, so no virus remained. On this basis, she discarded any possibility that the virus, or anything like it, was physically present at the Wuhan Institute of Virology.

Today the mine is inaccessible and surrounded by blockades and cameras, according to one local villager. The database of the Wuhan Institute of Virology which contains all its virus sequences and other important information has met a similar fate. It was shut off in September 2019. And what’s the official reason? To protect it from hackers during the pandemic; a puzzling explanation, considering Covid-19 was only reportedly identified months later.
