Released from quarantine in a hotel in Wuhan, China, this January, Peter Daszak made for the wildlife market linked to the first cases of a mystery pneumonia in the closing days of 2019. Back then, the Huanan seafood market was a jostling scrum of stalls selling not just seafood, but all manner of domestic and exotic wild animals, the living cheek by jowl with the dead.
It is now an empty shell, closed since the first cluster of cases of what morphed into the covid-19 pandemic. Daszak, a zoologist, visited earlier this year as a member of the World Health Organization-backed team sent to investigate the origins of the virus causing that illness, SARS-CoV-2, and assess what role the now-infamous market might have played.
No one yet knows, and hypotheses will take years to test. But it is clear that the Huanan outbreak was just a symptom of a sickness, not a cause of it. For two decades, evidence has been building of the link between how we encroach on, degrade and exploit the natural world and the risk of “zoonoses” – animal diseases that spill over into humans.
