The coronavirus outbreak poses a "very grave threat for the rest of the world", the head of the World Health Organization (WHO) said on Tuesday in an appeal for sharing virus samples and speeding up research into drugs and vaccines.
"With 99% of cases in China, this remains very much an emergency for that country, but one that holds a very grave threat for the rest of the world," WHO director-general Tedros Adhanom Ghebreyesus said in opening remarks to a meeting of more than 400 researchers and national authorities, including some participating by video conference from mainland China and Taiwan.
