In a move that some critics say should have happened 1 week ago, the World Health Organization (WHO) has declared the outbreak of a novel coronavirus in China a global health emergency. WHO Director-General Tedros Adhanom Ghebreyesus announced the move at a press conference on Thursday evening in Geneva. The new disease, first made public by China on 31 December 2019, has already spread to 18 countries; 7834 people have been infected and 170 of them, all in China, have died.
