Fairly unequivocal stance here on a particularly popular theory...
WHO team says lab virus leak theory extremely unlikely (rte.ie)
"Experts from the World Health Organization have all but eliminated a controversial theory that Covid-19 came from a laboratory in the Chinese city of Wuhan.
"The laboratory incident hypothesis is extremely unlikely to explain the introduction of the virus into the human population," said Dr Peter Ben Embarek, the head of the WHO mission.
"Therefore is not in the hypotheses that we will suggest for future studies."
He said the team's investigation had uncovered new information but had not dramatically changed the picture of the outbreak
Dr Ben Embarek also told a press briefing that work to identify the origins of the coronavirus points to a natural reservoir in bats, but it is unlikely that they were in Wuhan.
Earlier, the head of the China team said studies showed the virus "can be carried long-distance on cold chain products," appearing to nudge towards the possible importation of the virus - a theory that has abounded in China in recent months.
Liang Wannian also said there was "no indication" the sickness was in circulation in Wuhan before December 2019 when the first official cases have been recorded."
