Vietnam will deploy troops in Ho Chi Minh City and prohibit residents from leaving their homes, authorities said on Friday, as the country’s biggest city turns to drastic measures to slow a spiralling rate of coronavirus deaths. Vietnam’s toughest order yet comes amid a spike in fatalities and infections, despite weeks of lockdown measures in the business hub of 9 million people, the epicentre of the country’s deadliest outbreak. “We are asking people to stay where you are, not to go outside. Each home, company, factory should be an anti-virus fort,” Pham Duc Hai, deputy head of the city’s coronavirus authority, said on Friday. The government said it was preparing to mobilise police and military to enforce the lockdown and deliver food supplies to citizens.
