Russia saw the highest daily increase in confirmed coronavirus cases with 10,633 new cases on Sunday, for a total of 134,687, with more than half of the cases and deaths recorded in Moscow.
But the mortality rate has slowed in the past few days and is still relatively lower than in many other countries.
Russia said its lower mortality rate was due to the fact that the Russian outbreak was later than in many other countries, giving the authorities more time to prepare.
Russia's nationwide death toll rose to 1,280 on Sunday after 58 people had died in the past 24 hours, the Russian Coronavirus Crisis Response Center said on its website.
Russia has been partially banned since late March to curb the spread of the virus. People in Moscow can leave the house to go to the nearest grocery or pharmacy, go for a walk with their dog, or throw away garbage, but need special ID for other activities.
President Vladimir Putin has ordered the nationwide ban to remain in force until May 11, when Russia ends Labor Day and World War II Victory Day celebrations.
Moscow Mayor Sergei Sobyanin asked the residents on Saturday to continue to strictly isolate themselves during the long vacation.
Sobyanin said progress has been made in extending the tests so that authorities can treat those in need more quickly.
But he said the number of critically ill patients had increased, though not as strongly as the worst-case scenario. He said he thinks 2% of Moscow's 12.7 million population is infected, a much higher number than official statistics show.
"It is obvious that the threat is growing," he said on his website.
He told TV station Rossiya-1 that the Moscow authorities could reduce the number of digital permits issued to travel around the city if the situation worsened.
Prime Minister Mikhail Mishustin, the second highest official in Russia after Putin, told the President on Thursday that he had tested positive for coronavirus and had temporarily resigned to recover.
The first deputy prime minister Andrei Belousov is now incumbent prime minister in his absence.
Another Russian cabinet member, Minister of Construction Vladimir Yakushev, announced on Friday that he had been diagnosed with the virus and was being hospitalized. Dmitry Volkov, one of his deputies, was also tested positive, the ministry said.
