The Indian expert, 20, boarded a plane from his country to Vietnam’s Noi Bai International Airport on April 6, and was placed in quarantine upon arrival.

He tested positive on April 19 and was subsequently transferred to Hanoi-based Hospital of Tropical Diseases for medical surveillance and treatment.

Nine other patients are Vietnamese citizens with most of them in their 20s. They returned to Vietnam from India, the United States, Japan and Romania on different days.

They all tested positive during their stay in concentrated quarantine facilities, thus posing no risk to the community, said the MoH.

The same day, 15 COVID-19 patients were discharged from hospital after making a full recovery from the disease.

To date Vietnam has recorded 2,801 coronavirus cases, of whom 2,490 have been released from hospital.

The number of deaths caused by COVID-19 and related illnesses remains at 35.
