A man from Hanoi has retested positive for the novel coronavirus just two days after he was discharged from the hospital, according to the municipal Center for Disease Control.
N.A.D., a 55-year-old who comes from Dong Da District, Hanoi, had his sample taken for COVID-19 testing on Thursday, the center said on Saturday, adding that the result came back positive on Friday.
D. had been released from the hospital on Tuesday upon being cleared of the virus.
The patient is being isolated for treatment at the second branch of the National Hospital for Tropical Diseases in Hanoi.
His contacts have been identified, quarantined, and tested. None have been confirmed as coronavirus cases as of Sunday afternoon.
D. arrived in Vietnam from France on October 21 on board flight VN5010.
He was sent to centralized quarantine upon landing at Tan Son Nhat International Airport in Ho Chi Minh City.
He was then treated for COVID-19 at a medical center in Ba Ria-Vung Tau Province, over 100km apart from the city.
Vietnam has confirmed 1,365 coronavirus cases, with 1,220 recoveries and 35 virus-related fatalities, according to the Ministry of Health.
The Southeast Asian nation started denying entry to foreign nationals on March 22 but the government allows foreign experts, skilled workers, investors, and diplomats to enter the country on a case-by-case basis, subject to mandatory quarantine.
Though most regular inbound commercial flights are now suspended, charter planes to the country have been arranged to bring in experts, skilled workers, and diplomats, and to repatriate Vietnamese citizens stranded in other nations and territories due to the pandemic.
Vietnam currently charges international arrivals for quarantine.
It provided the quarantine service for free in the past.
