Russia reported a record 828 Covid-19 deaths in the latest day, as officials warned of a new wave of the pandemic.

The real number of deaths linked to the coronavirus is likely much higher, as the initial reports by the government’s Covid-19 task force are generally revised upward.

Moscow’s Deputy Mayor Anastasia Rakova said this week that the capital was reopening coronavirus hospital wards as cases spiked, according to Ria Novosti.
