1,340 Covid-19 patients were announced recovered, bringing the number of recoveries to 791,844.
Of more than 51,000 patients under treatment, 3,413 are severe cases.
The country has administered over 61.9 million Covid vaccine doses, including more than 17.8 million second doses.
As Vietnam has switched from the zero-Covid strategy to living with it, the country has issued a directive on evaluating the pandemic level in each locality that comprises two criteria: the proportion of people aged 18 and more getting vaccinated, and the number of new cases per 100,000 people in a week.
Based on those measurement tools, the government designates infected areas into red, orange, yellow and green, meaning 'very high risk, 'high', 'medium risk', and 'low risk.' Localities can decide to relax restrictions based on their risk levels.
Hanoi, Bac Ninh, Cao Bang, Lao Cai, Nam Dinh and Quang Ninh in the north, and Binh Thuan in the central region have classified themselves as 'low risk' areas, while Vinh Phuc, Hung Yen, Da Nang, Long An and Binh Phuoc are with medium risks.
HCMC is now a ‘high risk’ area.
