The highest number of new cases were in Moscow, the western Siberian region of Khanty-Mansiysk and Sverdlovsk in the Urals.
Russia’s fatality rate has remained low compared to other badly-hit countries, raising speculation that Moscow could be underreporting figures.
Russian authorities began easing anti-virus measures in June ahead of a massive World War II military parade in Moscow and a nationwide vote on constitutional reforms that now allow President Vladimir Putin to stay in power until 2036.
Both events were initially postponed due the epidemic.
Moscow opened cinemas and theaters on Aug. 1. In the capital, masks are mandatory in stores and on public transport but not in the streets.
Several institutes in Russia are working on a coronavirus vaccine.
The Russian Defense Ministry has said it developed a “safe” vaccine following clinical trials on a group of volunteers.
The trials are ongoing, and the Defense Ministry expects clinical trials to be fully completed in the coming weeks.
