Urban life in Ho Chi Minh City, Vietnam's largest metropolis, has ground to a halt as Covid-19 stalks the streets. 

The intersection by Saigon Opera House in District 1 is an echo of its former bustle these days.

Local photographer Nguyen Ngoc Thien captured similar scenes of the deserted city from 11 a.m. to 3 p.m, inspired by "The Great Empty" photo series in The New York Times.

The solitary Notre-Dame Cathedral, District 1, was built by French colonialists between 1863 and 1880. It has two bell towers that stand at a height of 58 meters.

Deserted streets leading to Thu Thiem Tunnel and Bitexco Financial Tower (middle) in District 1 which contains 68 floors, and is 262.5 meters in height.

At its completion in 2010, Bitexco Financial Tower became the tallest building in Vietnam. The country's tallest now is HCMC's Landmark 81 in Binh Thanh District, at 461.5 metres high.

Numerous restaurants, pubs and shops on Bui Vien Street, often packed with foreign tourists, have been shut to prevent the spread of Covid-19.

From March 28, 2020, HCMC authorities made it obligatory for people to wear masks in public places.

"This silence is probably a good opportunity for each of us to slow down, and reflect more on life. In difficult times, each individual should maintain a positive mindset and act more responsibly within their community, join hands with the Government and build a better Saigon," Thien said.

Vietnam started a nationwide social distancing campaign Wednesday, not allowing gatherings of more than two people in public. A prime ministerial directive also calls for people in the same families, villages, communes, districts and cities to stay put where they are for 15 days.

People should only leave home for emergencies, buying food and medicine, and working in factories, production facilities and businesses that involve trade in "essential" goods and services, the directive says.

The number of coronavirus infections in the country has gone up to 222, including 64 who have recovered and been discharged from hospital.
