The world has a “window of opportunity” to halt the spread of a deadly new virus, global health experts said, as the number of people infected in China jumped to 24,000 and millions more were ordered to stay indoors. The confirmed death toll in mainland China rose to 490 after hardest-hit Hubei province reported 65 more people had died. More than 20 countries have confirmed cases of 2019-nCoV, prompting the World Health Organization (WHO) to declare a global health emergency, several governments to institute travel restrictions, and airlines to suspend flights to and from China.
