The world has entered uncharted territory in its battle against the deadly coronavirus, the UN health agency warned, as new infections dropped dramatically in China on Tuesday but surged abroad with the US death toll rising to six. Globally, the virus has killed more than 3,100 people and infected over 90,000 even as a clear shift in the crisis emerges, with nine times as many new cases recorded outside China as inside, according to the World Health Organization. China has imposed draconian quarantines and travel restrictions to keep large swathes of the population indoors — a strategy that appears to have paid off as new cases have been generally falling for days.
