Ho Chi Minh City hospitals have released all COVID-19 patients after they had beaten the novel coronavirus, according to the Municipal Center for Disease Control.
The city has confirmed 77 coronavirus cases since the virus first hit Vietnam on January 23, the center said on Sunday.
All of the patients have recovered from COVID-19, it added.
Eight hundred and sixty-three people are being quarantined at centralized centers in the city, with 238 self-isolating at home or other lodging facilities.
The Ho Chi Minh City Center for Disease Control will continue monitoring arrivals from outbreak-hit regions.
The city has ceased taking samples at airports for COVID-19 testing since Friday.
Those who have left Da Nang, where a new viral wave erupted in July, since September 5 and then arrived in the southern city are required to declare their health status and to have their samples for COVID-19 tests taken at places designated by local medical centers.
Screening tests will continue to be conducted at wholesale markets and companies in the southern hub after no cases have been recorded at these places.
Ho Chi Minh City is now prepared to charge international arrivals for quarantine while local authorities have already started monitoring all crews of inbound international flights who stay in the city.
Health workers have conducted 5,273 tests on such flight crew members and found zero coronavirus infections so far.
