Geneva, February 13 : The World Health Organization's (WHO) team probing coronavirus origins, which is on a visit to China's Wuhan, the first Covid-19 hotspot, will publish a preliminary report next week, said WHO Director-General Tedros Adhanom Ghebreyesus on Friday.

The WHO chief said the Wuhan visit has been an important scientific exercise, adding that they are open to all hypotheses and require further analysis and studies. Addressing a press briefing, Tedros told reporters, "Some questions have been raised as to whether some hypotheses have been discarded. Having spoken with some members of the team, I wish to confirm that all hypotheses remain open and require further analysis and studies."
