All hypotheses on Covid-19 origins still being investigated, says WHO boss

Comments from Tedros Adhanom Ghebreyesus came after another WHO expert said laboratory theory was extremely unlikely'

The World Health Organization says it has not ruled out any theory on the origins of the coronavirus pandemic, despite one top official earlier this week appearing to dismiss the idea it had escaped from a laboratory.

Speaking at a briefing on Friday, Dr Tedros Adhanom Ghebreyesus, director-general of the WHO, said a summary report from the organization's team sent to Wuhan to investigate the origins of the virus should be published next week, with a full report coming soon after.
