WHO mission to China fails to find source of coronavirus


The WHO mission to China to uncover the origins of the coronavirus has failed to identify the source of the pandemic but the team on Tuesday ruled out the Wuhan lab-leak theory propagated by Donald Trump.

Experts believe the disease — which has killed more than
2.3 million people worldwide — originated in bats and could have been
transmitted to humans via another mammal.

World Health Organization foreign expert Peter Ben Embarek
said identifying the animal pathway remains a “work in progress”, and
the absence of bats in the Wuhan area dimmed the likelihood of direct
transmission.

It was “most likely” to have come from an
intermediary species, he said. He also backed up China’s position that there
was no evidence of “large outbreaks” in Wuhan before December when
the first official cases were recorded.

Animals such as rabbits, ferrets and bamboo rats could be
the intermediary, another team member Marion Koopmans added, saying they might
be an “entry point” for further investigations.

Liang Wannian, head of the China side of the joint mission,
said animal transmission remained the likely route, but “the reservoir
hosts remain to be identified”.

Ben Embarek quashed the theory that a leak from a virology
lab in Wuhan could have caused the pandemic.

“The laboratory incident hypothesis is extremely
unlikely,” he said. It “is not in the hypotheses that we will suggest
for future studies”.

The mission was a diplomatically knotty one — presaged by
fears of a whitewash — with the US demanding a “robust” probe and
China firing back with a warning not to “politicise” the
investigation.

The WHO experts spent a month in China including two weeks
in quarantine.

Liang said studies showed the virus could be “carried
long-distance on cold chain products”, appearing to nudge towards the
theory the virus was imported — an idea that has abounded in China in recent
months.

Ben Embarek said “the virus can persist and survive in
conditions that are found in these cold and frozen environments”.

“But we don’t really understand if the virus can then
transmit to humans and under which conditions this could happen,” he said.

Beijing is desperate to defang criticism of its handling of
the chaotic early stages of the outbreak.

It has tried to refocus attention on its handling and
recovery while floating the theory that the virus emerged abroad and was
brought into China possibly via frozen foods.

Koopmans said the next steps could include searching for
“earlier circulation” of the virus.

Reporters were largely kept at arms’ length from the experts
during their closely-monitored visit, but snippets of their findings crept out
via Twitter and interviews.

Questions have been asked about the relevance of some of
their activities to their stated aim of finding the virus source — including a
visit to a propaganda exhibition celebrating China’s recovery from the
pandemic.

The group spent just an hour at the seafood market where
many of the first reported clusters of infections emerged over a year ago.

They also appeared to spend several days inside their hotel,
receiving visits from various Chinese officials without venturing out into the
city.

Research was carried out at the Wuhan virology institute
where they spent nearly four hours. They met with Chinese scientists there
including Shi Zhengli, one of China’s leading experts on bat coronaviruses and
a deputy director of the Wuhan lab.

Scientists at the laboratory conduct research on some of the
world’s most dangerous diseases, including strains of bat coronaviruses similar
to Covid-19.

Former US president Donald Trump frequently repeated a
controversial theory that a lab leak may have been the source of the pandemic.
