My country seemed to have all the ingredients for a coronavirus disaster, so what has it done right?
On the evening of 7 March 2020, I received an email from the manager of the office building where I work in central Hanoi. It said the father of Nguyen Hong Nhung, the 17th Covid-19 patient in the country and first in the city, had dined on the third floor of the building the night before. Although he had twice tested negative for the virus, the building managers had reported his presence to the authorities. Seven staff who had been in contact with him were isolated and the building was immediately cleaned with disinfectant spray.
