Russia on Thursday reported another record increase in coronavirus infections with more than 11,000 new cases as Moscow imposes new virus restrictions and ramps up testing.

A daily government tally of virus cases in the country saw 11,231 new infections in 24 hours, bringing Russia's total to 177,160. Russia now ranks fourth in the overall number of reported virus cases in Europe and fifth in the world, according to an AFP tally.

The number of infections in Russia has been rising by more than 10,000 a day since Sunday, in contrast to countries in western Europe that are taking steps to ease lockdown measures. Officials attribute the increase to mass testing and detecting asymptomatic cases not always counted in other countries.

Health officials said on Thursday they had carried out more than 4.8 million tests. Russia's mortality rate is low compared to European countries hit badly by the pandemic, with health officials registering 88 new deaths for a total of 1,625.

Moscow cites a series of measures taken early in the pandemic for its low mortality rate, including closing its borders and ordering the elderly and those at risk to self-isolate. But some say the discrepancy is due to how the death count is calculated.

According to official figures on Wednesday, Russia's death rate was just 0.9 percent, compared with Germany, which is lauded for its virus response, with a fatality rate of 4.2 percent. Coronavirus cases have been registered in all of Russia's 85 regions with Moscow the epicentre of the pandemic where officials have registered 92,676 infections.

The capital's mayor Sergei Sobyanin said Thursday that Muscovites will be required to wear masks and gloves on public transport as restrictions ease and some sectors return to work. "We understand that the number of people moving on transport will increase, one way or another, the number of people communicating with each other will increase," he said on the Rossiya-24 television channel.

A non-working quarantine period is in place in Russia until May 11, but Sobyanin has said that stay-at-home restrictions would remain in place beyond this deadline. Moscow residents are allowed out only for brief trips to a shop, to walk dogs or to travel to essential jobs with a permit.

President Vladimir Putin on Wednesday ordered regional governors to develop plans to gradually lift anti-virus lockdowns regimes which vary from region to region. He urged caution, however, warning: "The price of even the smallest mistake is the safety, lives and health of our people."

Since the start of the crisis, Putin's approval rating has dropped to a historic low, according to independent pollster Levada, which said this week it fell to 59 percent in April from 63 percent in March.
