The Ministry of Health has sent a document to cities and provinces, proposing to extend quarantine time in centralised quarantine areas starting from early May 5 to curtail community transmission.
Accordingly, people who complete the mandatory 14-day quarantine and test negative twice will have to still remain in centralised quarantine areas, including both military-run and civil quarantine areas.
The move is in line with the request of Deputy Prime Minister Vu Duc Dam, who is head of the Steering Committee for COVID-19 Prevention and Control.
The decision was made after some patients tested positive for COVID-19 after undergoing the 14-day quarantine and tested negative twice, resulting in further infections in the community.
In the past six days, Vietnam detected at least three such cases, with the latest detected case being an Indian man, who was diagnosed on Tuesday morning (May 4) in Hanoi. The first two cases resulted in several community infections, with 37 cases recorded so far in five localities, including Hanoi and Ho Chi Minh City.
