Accordingly, all concentrated quarantine facilities have been told not to release people after they complete the 14-day quarantine period, and test negative for novel coronavirus twice.
This came after some people who completed their two-week duration tested positive for the virus after leaving quarantine sites.
The new quarantine measure is applied from 0:00 on May 4 until further notice from the National Steering Committee on COVID-19 Prevention and Control.
Most recently, an Indian expert, who works for local automaker Vinfast, has been confirmed with COVID-19 in Hanoi. The man, born in 1984, arrived in Vietnam on April 17 and was immediately put under 14-day quarantine at a hotel in Hong Bang district, the northern city of Hai Phong.
He tested negative for the virus twice during the mandatory quarantine period, and left for Hanoi on May 1 to stay with his wife and children at Park 10, Hoang Mai district’s Times City.
Authorities are actively tracing people having close contact with him for COVID-19 test and quarantine to prevent the virus spreading further.
