The Communist nation has recorded 7,572 cases and just 48 deaths since January of last year, according to a New York Times database. By contrast, nearby Malaysia, which imposed a national lockdown on Tuesday, has recently recorded higher case numbers in a single day. But the church cluster in Ho Chi Minh City, outbreaks at factories in the country’s north and the emergence of a troubling new variant all suggest that Vietnam’s luck may be running out. More than half of the country’s cases have occurred in the past month... On Monday, the government ordered a two-week lockdown of the Go Vap District of Ho Chi Minh City, home to about 700,000 people and the neighborhood in which the couple’s church, Revival Ekklesia Mission, is located. Residents were ordered to stay home as much as they could, work from home if possible, avoid other people and wear masks in public. A smaller part of the city, Thanh Loc Ward in District 12, was placed under the same order. Large gatherings have been banned across the city, Vietnam’s most populous, and the government said it planned to test its nine million inhabitants.
