A new group of 26 scientists to drive further research into the coronavirus origins may be “our last chance” to understand where the virus came from, a World Health Organization official said on Wednesday.
Nearly two years after the first reports emerged of an unknown pneumonia sickening people in the central Chinese city of Wuhan, how the new coronavirus first began spreading remains unclear and is entangled in geopolitical tensions and scientific debate.

Now, the WHO is attempting to tamp down any rhetoric with the establishment of the Scientific Advisory Group for the Origins of Novel Pathogens. Known as Sago, the permanent body will guide future studies on the origins of the virus that causes Covid-19 and other outbreaks of “pandemic potential”, and create a framework for how to investigate the origins of pathogens in future outbreaks.

“This has never been an easy process in many countries,” said WHO health emergencies programme executive director Michael Ryan at a briefing on Wednesday.

“We’ve had difficulties in the past in a number of countries … because there were real issues, there are sensitivities, there are economic issues, there are national pride issues, there are sovereignty issues, and you can’t ignore that they exist – if you ignore that they exist you will crash and burn on those issues,” Ryan said.

“This is our best chance – and it may be our last chance – to understand the origins of this virus in a collegiate, collective and mutually responsible way,” he said.

What will Sago do?
