All people who have completed their 14-day quarantine period in Vietnam are required to remain at their quarantine facilities from 0:00 on Tuesday until further notice, the Ministry of Health announced.
The move was made after the country had recorded 37 local COVID-19 patients since April 27.
These infections were linked to two people who had completed their 14-day quarantine period in central Da Nang City and northern Yen Bai Province.
The two people had also met the condition of testing negative for the virus at least twice before being discharged from the centralized quarantine facilities.
Currently, 561 people are being quarantined at hospitals, 22,522 are being monitored at other facilities, and 17,422 are self-quarantining at home in Vietnam, according to the verified Facebook page of the Vietnamese government.
Vietnam has logged 2,985 COVID-19 infections, including 1,607 locally-transmitted cases, since the pathogen first struck the nation on January 23, 2020, according to the health ministry’s data.
Recoveries have hit 2,560 while 35 patients have died, most having suffered from critical pre-existing conditions.
