The WHO chief yesterday called for China to co-operate better in the next phase of investigations into the origins of the pandemic, demanding more access to raw data.
Tedros Adhanom Ghebreyesus told reporters in Geneva that the UN health agency had developed a framework for moving forward with the second phase of the vital investigation into where Covid-19 came from.
“We hope there will be better co-operation to get to the bottom of what happened,” he said.
The WHO chief pointed to several problems during the initial probe.
“One problem is sharing raw data and I said it at the conclusion of the first phase, that there is this problem and it has to be addressed,” he pointed out.
Another issue he acknowledged was that “there was a premature push to...especially reduce one of the options like the lab theory.”
The UN health agency has been facing intensifying pressure for a new, more in-depth investigation of Covid-19’s origins.
The WHO only managed to send a team of independent, international experts to Wuhan in January, more than a year after Covid-19 first surfaced there in late 2019, to help probe the pandemic origins.
But in their long-delayed report published in late March, the international team and their Chinese counterparts drew no firm conclusions, instead ranking a number of hypotheses according to how likely they believed they were.
The report said the virus jumping from bats to humans via an intermediate animal was the most probable scenario, while a theory involving the virus leaking from a laboratory was “extremely unlikely”.
The investigation and report have faced criticism for lacking transparency and access, and for not evaluating the lab-leak theory more deeply — a mere 440 words of the report were dedicated to discussing and dismissing it.
Long dismissed as a right-wing conspiracy theory, and vehemently rejected by Beijing, the idea that Covid-19 may have emerged from a lab leak has been gaining increasing momentum in the US especially.
Tedros, who has continued to insist that all theories remain on the table, insisted yesterday that more investigation was needed.
“I was a lab technician myself, an immunologist, and have worked in the lab, and lab accidents happen,” he said. “It’s common. I have seen it happening,” he said, stressing that “checking what happened, especially in our labs, is important.”
“We need information, direct information on what the situation of these labs was before, at the start of the pandemic.”
The WHO chief had previously lamented that the international team did not have access to all the raw data needed to make a proper assessment.
For the next phase of the investigation, he said, “I hope there will be better co-operation, and we have continued the engagement with China, and also with (other) member states,... to get into the bottom of what happened.”
Pointing to the more than 4mn official deaths from Covid worldwide, the WHO chief said: “I think we owe it to them to know what happened.”

Coronavirus deaths in Africa surge
Africa recorded a 43% jump in Covid-19 deaths last week as infections and hospital admissions have risen and countries face shortages of oxygen and intensive-care beds, the World Health Organisation said yesterday. The continent’s case fatality rate – the proportion of deaths among confirmed cases – stands at 2.6% against the global average of 2.2%, WHO Africa said in its weekly briefing. “Africa’s third wave continues its destructive pathway, pushing past yet another grim milestone as the continent’s case count tops 6mn,” Matshidiso Moeti, WHO regional director for Africa, told the briefing. The surge in infections, which is partly driven by the presence of the highly transmissible Delta variant of the coronavirus in 21 African countries, is leaving a “brutal cost in lives lost” in its trail, she said. Deaths have climbed steeply for the past five weeks to 6,273 last week, just a percentage point shy of its weekly peak recorded in January.
“This is a clear warning sign that hospitals in the most impacted countries are reaching a breaking point,” Moeti said.
