HANOI (Reuters) - Vietnam began mass coronavirus testing in the capital Hanoi, banned gatherings in its economic hub and urged tens of thousands of domestic travellers to report to authorities on Thursday, as the country scrambled to contain its first outbreak in 100 days.
Text messages were sent to all cellphones used by the country's 95 million people urging anyone who visited the popular coastal city of Danang in July to come forward, after a new wave of the virus spread to six cities and provinces in as many days, with 47 positive cases.
