Cover-ups, coincidences, and conspiracy theories: where did Covid come from?

John Sudworth was the BBC's China correspondent when an unexplained pneumonia started worrying Wuhan doctors in December 2019. Since then, he's been investigating the origin of the virus that would turn into a devastating global pandemic.

From the beginning, there have been claims of certainty. Many scientists say the virus that causes Covid came from nature - probably carried from bats to other animals, and then to humans in a Wuhan market.

But an alternative possibility - that it leaked from a laboratory - has refused to go away. And other scientists claim there's uncertainty. For them, the mystery of Covid's origin remains unsolved.

So, where did Covid come from? For every one of the millions of lives lost, for every long sufferer, for the pain, the isolation, and the incalculable economic cost, the answer matters. It might also help us prevent another - maybe even worse - pandemic.

But it's a debate that's become politicised, toxic, and a bit crazy.

    8. An Answer

    Speculation that newly declassified US intelligence will contain smoking-gun evidence.

    Three years on from the start of the pandemic, the FBI - the US domestic intelligence agency - reveals it sees a lab leak in Wuhan as the most likely source of Covid. Weeks later, the US Congress passes a law requiring the country’s intelligence agencies to declassify information they have that potentially links the Wuhan Institute of Virology with Covid’s origin. What will it reveal? And, in our final episode (for now at least), what conclusions can we reach about that question that’s sparked so much controversy and acrimony: where did Covid come from?

    7. The Suspicion Business

    7. The Suspicion Business

    Mysterious deaths in Soviet Russia and what they might tell us about the origin of Covid.

    When US intelligence agencies blamed a spate of unexplained Russian deaths in 1979 on a leak from a bioweapons facility, the Soviet government responded angrily, saying the cause was natural. A top US scientist stepped in to find the truth - and was given anything but. Does pointing the finger of blame creative a disincentive for governments to cooperate more fully? Or should information from inside authoritarian states be treated with suspicion? A Chinese insider has a set of striking revelations and someone who dismissed conspiracy theories now has one of his own.

    6. Back to the Market

    What really went on in that Wuhan market - and the curious case of the raccoon dog.

    It’s the early hours of 31 December 2019 and a cleaning squad is moving through the narrow lanes of a large, covered market in the Chinese city of Wuhan. The Huanan Seafood Market has been linked to a number of cases of a mysterious new illness circulating in the city, suggesting that animals there might be the source. But the World Health Organization would later say there were no verified reports of live mammals for sale. So what’s the truth about the market? And why have raccoon dogs sparked yet another bitter scientific dispute?

    5. Labs, Safety, and Risk

    The lab leak theory goes mainstream. How safe are top-security laboratories?

    After the World Health Organization’s attempts to find the origin of Covid effectively rule out a lab leak, there’s a backlash. A new US president helps bring the lab leak theory into the mainstream. What are the dangers involved in the work being done in virology laboratories? How effective are their safety measures? And do the benefits of their work outweigh the risks? John visit’s a top biosafety lab to find out.

    4. Mission: Impossible

    A World Health Organization team heads to Wuhan. Will they find the truth?

    As the first year of the Covid outbreak draws to a close, a team of international scientists chosen by the World Health Organization is preparing to visit the city where it all started to investigate the virus’s origin. But with the Chinese government closely involved in the mission, how free will they be to find the truth? And is a researcher with links to the Wuhan Institute of Virology the right person to be asking questions about a possible lab leak?

    3. Uncertainty and Trump

    US President Donald Trump wades into the Covid origins debate.

    It’s April 2020 and at the podium of the White House’s press room, Donald Trump makes a geopolitically incendiary claim: he has a high degree of confidence that the origin of the virus that causes Covid is the Wuhan Institute of Virology - a Chinese government lab. But scientists seem certain that can’t be true. So what is the evidence for both claims? And what were the scientists publicly dismissing a lab leak saying in private?

Well done the BBC

For revealing just how corrupt the WHO is and how easy it is for dictatorships to buy scientific conclusions. Shame on them all. I guess their lack of attention at school, dysfunctional parental love and limited social skills makes scientists easy targets for bribes.

Marc O'Polo ,

Very good but

..what about the manipulation of the virus (for whatever reason and specific to human respiratory diseases) and the insertion of the furin cleavage site that was alluded to earlier and also mentioned by Matt Ridley in his recent book..

Piplid ,

XL Curate’s Egg?

Determined and granular investigation?Spinning a collapsing narrative? Tartarean burying of the lead? level headed review on a polarising subject? A cry for help from inside the Overton window?

I really not sure what to make of these. There are some interesting primary source nuggets buried in here but I found the podcasts themselves can be flat and at times repetitive.

What I am certain of is that the music is God-awful.
