Moscow mayor on Monday introduced quarantine for those over-65 and people with chronic problems.
The restrictive measures come into force starting from March 26, Sergey Sobyanin said in a statement published on his official website.
"The nature of the coronavirus is such that it primarily poses a threat to the life and health of the elderly and people with chronic diseases and low immunity. So our main task is to protect you -- Muscovites of the older generation.
From March 26 to April 14, Muscovites over-65 and citizens suffering from chronic diseases such as diabetes, asthma, chronic kidney disease, or cancer, as well as those who have suffered a heart attack or stroke are required to comply with the home regime. If you are working, please do not go to work," Sobyanin said.
The mayor published a phone number of a volunteer center, urging people to use the help of volunteers in case of necessity to buy food or medicines, and informed of a one-time payment to compensate expenses during self-isolation.
He also prohibited the mobile communication providers to stop serving over-65 and customers with chronic problems even if they did not pay the services.
In a separate statement, Russia's Prime Minister Mikhail Mishustin also asked the elderly to stay at home and avoid gatherings.
