According to the Saturday morning report from the National Steering Committee for COVID-19 Prevention and Control, the total number of people in Việt Nam who have tested positive remained at 270.

But five previously certified recovered COVID-19 patients have tested positive again for SARS-CoV-2, according to the report.

Patient No.188 was discharged from Hà Nam General Hospital on April 16 after her results came back negative twice.
