The death toll in China from the new coronavirus epidemic jumped on Wednesday, as the chief of the World Health Organization urged countries to work together against the “grave threat” posed by the outbreak. The WHO is holding a conference in Geneva on combating the virus, which has killed more than 1,100 people in China and spread to dozens of countries around the world. WHO chief Tedros Adhanom Ghebreyesus said viruses could have “more powerful consequences than any terrorist action”.
