Moscow has announced a prison term of up to five years for those who fail to self-isolate, as governments around the globe ramped up measures to stop the spread of the coronavirus.
The number of people worldwide who have now tested positive for COVID-19 , the disease caused by the coronavirus , has passed 107,000 - with more than 3,600 deaths.
Officials in the Russian capital, where cases total 15, on Sunday announced a "high alert regime" and a jail term of up to five years for anyone who fails to self-isolate at home for two weeks after visiting countries most severely hit by the coronavirus outbreak.
This includes people returning from China, South Korea, Iran, France, Germany, Italy and Spain, with checks carried out via CCTV.
Meanwhile, Iran declared a "sacred jihad" against the virus after more than 1,000 infections were confirmed overnight, taking the country's total to 6,586 cases, including 49 new fatalities, bringing the number of deaths to 194.
This was shortly followed by a report by the state-controlled IRNA news agency that IranAir had stopped all flights to European destinations.
In Italy, the government has introduced tough new measures to try to stop the spread of coronavirus, which includes ordering a lockdown across the hardest-hit region of Lombardy, plus 14 other northern and central provinces.
It follows a 1,247 rise in COVID-19 cases - the country's biggest daily increase since the outbreak started in the north of the country on 21 February.
In China, a hotel being used to house people in coronavirus quarantine collapsed killing at least 10 people and trapping more than 20 others. So far, at least 47 people have been rescued from the building in the city of Quanzhou, in southeastern Fujian Province.
The country also reported 44 new cases on Sunday in a 24-hour period - the lowest level since it began publishing nationwide figures on 20 January - and 27 new fatalities.
South Korea , the hardest-hit country outside China, reported 272 new cases, taking its total to 7,313 with 50 deaths overall.
Prime Minister Chung Sye-kyun urged citizens to "actively cooperate" and "show a mature sense of civil awareness" with the efforts to make sure healthcare workers and the sick "who really need face masks" are able to access or buy them.
As Argentina announced the first death from the disease in Latin America - a 64-year-old patient from Buenos Aires - Western countries looked to imitate Chinese containment measures by imposing travel controls and shutting down public events.
Sports events with spectators and school trips were banned for two weeks - and recreational centres for pensioners shut down for four weeks - in Greece, after cases there rose by seven to 73.
Spain deployed police to enforce a quarantine. Austria confiscated 21,000 disposable masks that a Turkish company smuggled aboard a tour bus, seeking to profit from soaring demand.

Even islands in the middle of the Indian Ocean have not been spared, as the Maldives reported its first two cases and authorities locked down two tourist resorts.
Cruise ships have increasingly been in the spotlight as they seek safe harbour on four continents amid fears they are spreading the virus.
At the weekend, they faced trouble in waters off California, Malaysia, Egypt and Malta as those aboard were tested or confined to cabins.
Officials in California are deciding where to dock the Grand Princess cruise ship, after 21 people on board tested positive for COVID-19.
There is evidence the ship, now idling off San Francisco, was the breeding ground for a deadly cluster of almost 20 cases during an earlier voyage.
Hundreds of people were also forced to remain on a Carnival Panorama cruise ship docked in Long Beach, California, while tests were carried out on a sick passenger.
In Egypt, a cruise ship on the Nile with more than 150 people on board is under quarantine in the southern city of Luxor after 12 positive tests.
In the port of Penang in Malaysia, the Costa Fortuna has been turned away because 64 of the 2,000 passengers aboard are from Italy. The ship had already been rejected by Thailand, and is now heading to Singapore.
And in Malta, which recently reported its first case of the virus, the MSC Opera ship agreed not to enter the Mediterranean country's port amid local concerns - even though there are no infections suspected on board.
The ship continued on to Messina, Sicily, where passengers were allowed to disembark after officials reviewed medical records.

While many scientists say the world is clearly in the grip of a pandemic - a serious global outbreak - the World Health Organisation (WHO) is not calling it that yet, amid concerns the word might cause more alarm.
The virus is still much less widespread than annual flu epidemics, which cause up to five million severe cases around the world and up to 650,000 deaths annually, according to the WHO.
