W.H.O. officials said the group would assess recent studies, including those describing bats harboring close relatives of the virus behind Covid-19, and advise the organization on what future studies were needed — potentially including field research in China.
China has reacted angrily to the idea that the virus may have emerged from a lab and, analysts have said, is almost certain to resist outside requests to visit research centers, bat caves or wildlife farms within its borders.
Unlike the last W.H.O. team, which was assembled specifically for the visit to China, the new committee will also have a mandate to weigh in on the emergence of any new pathogens beyond the coronavirus, giving it a permanence that the W.H.O. hopes will help insulate it from political squabbling.
At a news briefing on Wednesday, Dr. Michael Ryan, the executive director of the W.H.O. Health Emergencies Program, said it was impossible to ignore obstacles like “national pride” standing in the way of hunting down the origins of the coronavirus. But he said the new advisory group was an effort to return to the scientific issues at the core of that effort.
“This is our best chance,” he said. “And it may be our last chance to understand the origins of this virus in a collegiate and collective and mutually responsible way.”
