Da Nang currently has more than 276,000 households, of which over 44,000 have at least one member already tested for the novel coronavirus before May 18.
From then to Friday, about 115,000 other households had had their representatives tested.
Of the 115,000 tested people, 32,000 cases tested on Friday were still awaiting results while only seven cases of the 83,000 other samples had their results return positive for the virus.
The source of infection of one case remained unknown while other six cases were direct contacts of confirmed patients.
With this results, Ton That Thach, director of the Da Nang Center for Disease Control, said that the city is considerably clear of COVID-19.
Previously, Prime Minister Pham Minh Chinh honored the center for its breakthrough in COVID-19 testing.
