ĐÀ NẴNG — A COVID-19 patient who tested positive again on Monday, 14 days after leaving hospital having been declared healthy, tested negative for SARS-CoV-2 on Friday afternoon.

Patient 424 will need more negative tests during her quarantine at a hospital in the coming days.

The city’s Centre for Disease Control (CDC) said the patient had been released from Hòa Vang field hospital on August 10 after 14 days of treatment and isolation. She had tested negative for SARS-CoV-2 three times before leaving the hospital for two weeks of isolation at home.

In the last test at home after completing 14-day home isolation, the patient tested positive again for SARS-CoV-2 and was taken to a hospital along with three relatives for quarantine on Monday.

Doctors from Đà Nẵng General Hospital said it was the first such case in the city since the coronavirus outbreak on July 25, but they said this case would unlikely cause further infections.

The three relatives of patient No 424 have all tested negative for SARS-CoV-2.

Doctors from the CDC said the patient needs at least two negative tests to leave the hospital and she will then be isolated at home, as will her relatives, for two weeks and must test negative twice more.

The CDC also said 3,211 foreigners in Đà Nẵng had tested negative for SARS-CoV-2. All medical samples of foreigners were tested using real-time polymerase chain reaction (PCR).

Also on Friday, social distancing orders were lifted in Hội An City, Điện Bàn Town and Duy Xuyên District in the central province of Quảng Nam as no cases of SARS-CoV-2 in the community have been reported in 14 days.

Coffee shops and restaurants are opened, but all gatherings are limited under 20 people.

Bus routes from Quảng Nam to Đà Nẵng and Quảng Ngãi, as well as taxi and tour cars, are still banned. — VNS
