MOSCOW, Russia— Russia’s tally of confirmed coronavirus cases surpassed 1.5 million on Sunday as authorities reported 16,710 new infections amid a rapid resurgence of the outbreak that has swept the country in recent weeks.

Russia’s caseload remains the fourth largest in the world. The government’s coronavirus task force has also registered a total of over 26,000 deaths since the beginning of the pandemic.

The task force has been reporting over 15,000 new infections every day since last Sunday, which is much higher than in the spring, when the highest number of daily new cases was 11,656.

Despite the sharp spike in daily new infections, Russian authorities have repeatedly dismissed the idea of imposing a second lockdown or shutting down businesses after most virus-related restrictions were lifted during the summer. In some Russian regions, officials urged the elderly to self-isolate at home and called on employers to have at least part of their staff work from home. Several regions have shut down nightclubs and limited the hours of restaurants and bars.
