The city government had announced a “high alert regime” and imposed extra measures on Thursday to prevent a spread of the illness in the Russian capital.

Those who return from China, South Korea, Iran, France, Germany, Italy and Spain and other states showing possible “unfavorable” signs of coronavirus should self-isolate themselves at home for 14 days, Moscow city hall has said.

The Moscow healthcare department said on Sunday that those disregarding the regulation risked severe punishment including imprisonment of up to five years.
