The city reported 791 cases on Friday, totaling 13,670 ones across the nation today and 1,280,780 cases since the outbreak of the pandemic 22 months ago.
On Friday, only two other cities reported more cases than Hanoi: the southern city of Can Tho (892) and Ho Chi Minh City (1,311), the epicenter of the fourth and current wave of the pandemic.
The Ministry of Health also reported 200 Covid-19 deaths, so the death toll rose to 25,858.
Two days ago, Vietnam reported its second highest number of cases since the outbreak of the pandemic (14,508). This country had not reported a number as high as this since September 3, when the number of cases amounted to 14,894.
In late October, with the aim to revive the economy, the government lifted stricter health regulations and gradually reopened industries and businesses, but daily cases tripled in just one month.
Health authorities are working hard to speed up the vaccination campaign in order to save lives or attain collective immunity.
In a country of nearly 98 million inhabitants, only slightly more than 53 million Vietnamese have been fully vaccinated.
