Thanks to strict quarantine measures and an aggressive and widespread testing programme, Vietnam has kept its virus total to an impressively low 415 cases, and had reported no locally transmitted infections for 100 days.
But on Friday, Vietnam’s health ministry said in a statement that a 57-year-old man from Danang, a popular tourist hotspot, had tested positive three times for the virus, prompting the isolation of 50 people he came in contact with.
One hundred and three people connected to the patient were tested for the virus but all returned negative results, the statement said.
The health ministry has not officially confirmed the case as COVID-19, which comes at a time when Vietnam was about to resume international commercial flights and as domestic tourism is surging.
It did not say how the man contracted the virus, but said he had not left Danang for nearly a month. He was initially diagnosed with pneumonia.
Late on Friday, authorities in Hanoi reinstated a recommendation to wear masks in public places as Vietnam’s benchmark VN Index closed down 3.22%.
