The Vietnamese Ministry of Health logged zero local COVID-19 infections for the eighth successive day on Thursday, alongside three recoveries.
Vietnam’s domestic cases since January 23, when the novel coronavirus first hit the country, remains at 691, the health ministry said.
Three recovered patients were recorded on Thursday, including two in Da Nang and one in Hanoi, it added.
Vietnam has documented 1,059 coronavirus cases, with 893 recoveries and 35 deaths as of Thursday night.
The country started dealing with a new wave of infections on July 25, when coastal Da Nang detected the first local case after 99 days of zero community-based transmissions nationwide.
A total of 551 domestic infections, most linked to the beach city, have been confirmed across the nation ever since.
The virus is now under control after the Vietnamese government spent over a month conducting aggressive contact tracing.
Da Nang authorities have eased social distancing restrictions, resuming inter-city transportation and certain services.
Vietnam is quarantining 36,126 people who had close contact with infected patients or entered the Southeast Asian country from outbreak-hit regions.
Ho Chi Minh City authorities have said those coming to the city from Da Nang from September 5 will have to declare their health status, monitor their health for 14 days, and undergo a COVID-19 test.
The Ho Chi Minh City Center for Disease Control already began testing arrivals from Da Nang at Tan Son Nhat airport on Tuesday.
People who come to the city by other means of transportation will be required to declare their health conditions and to have their samples taken at places designated by local medical centers.
