Michael Ryan, the WHO’s emergencies director, said it may be the “last chance to understand the origins of this virus” in a collegiate manner. The WHO announced earlier this year it would set up a Scientific Advisory Group for the Origins of Novel Pathogens (Sago). Maria Van Kerkhove, the WHO’s technical lead on Covid-19, said Sago would urgently assess what was now known, what still remained unknown, and what rapidly needed to be done.
“I anticipate that the Sago ... will recommend further studies in China and potentially elsewhere,” she said. “There’s no time to waste in this.”
