Wet markets and the coronavirus

Where the coronavirus came from and why these diseases aren't a one-off. Manuela Saragosa speaks to Dr Juan Lubroth, former chief veterinary officer at the UN's Food and Agricultural Association in Rome, about the risks around so-called 'wet' markets prevalent in East Asia and South East Asia where live animals are sold. Professor Tim Benton, research director of the emerging risks team at the think tank Chatham House tells us why animals are often the source of pathogens that go on to affect humans. Patrick Boyle, a bioengineer with US biotech company Gingko Bioworks, describes the work to develop vaccines. Catherine Rhodes from the Biosecurity Research Initiative at Cambridge University tells us why she's not surprised governments are underprepared for the pandemic.
