Scientists want to determine how the virus propelled species onto humans. A year after the start of the pandemic, many questions remain unanswered about the origins of the new virus.
The Guardian’s health editor, Sto Boseley, tell Rachel Humpheys on what WHO has discovered over the past 12 months and the challenges it has faced. Ideally, door-to-door detective work, speaking to the first people to fall ill as well as their families and colleagues, would have started in Wuhan in January.
