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 aiports for COVID-19 testing since Friday.

Those who having 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.

On July 25, Da Nang, a touristy city on the central coast, recorded the first local COVID-19 case after Vietnam had gone 99 days without documenting any domestic transmission, the Ministry of Health said. A total of 551 locally-transmitted cases have been registered nationwide from that date, most traced back to the coastal city.

Ho Chi Minh City has logged 16 cases since then, including eight linked to the beach city and eight imported infections. All have exited hospitals.

Vietnam confirmed three imported cases on Sunday, all Vietnamese returning from Russia, taking the national tally to 1,063, according to the Ministry of Health. They are isolated for treatment at a hospital in south-central Phu Yen Province.

Eigth patients were declared free of the pathogen the same day, with recoveries having reached 918.

Thirty-five patients have died, most having suffered critical comorbid conditions.

The death toll did not include three COVID-19 patients who passed away after they had tested negative for at least three time.

The country has recorded zero community transmission for 11 days on end.
