Russia has reported a record daily high of coronavirus deaths for two straight days amid the continued spread of the virus in the country. Hospitals in some regions are under acute strain.
The Russian government reported 37,120 new cases of coronavirus on Saturday, with a record 1,254 fatalities.
In the Primorsky Territory in Russia's Far East, the occupancy rate for hospital beds has reached about 90 percent.
The situation has forced many COVID-19 patients to isolate in their homes.
A clinic in the region's central city of Vladivostok says its doctors are busy dealing with about 250 requests every day for house calls from patients staying at their homes.
The region also has an acute shortage of medical workers. About 90 medical students have been sent to help out with its vaccination program.
Russia's inoculation program has been delayed, partly due to people's distrust of Russian-made shots.
The Russian government is trying to step up coronavirus restrictions. It has submitted to parliament a bill that would require airplane and train passengers as well as visitors to cultural facilities to present vaccination certificates, starting from next February.
