Across Europe, an increasing number of countries have been shutting down borders, restaurants and public gatherings in hopes of limiting the spread of the coronavirus.

He added that German citizens in the neighboring countries will be allowed back in.
The government of France, meanwhile, is putting together a partial lockdown order that is set to go into effect at midnight Tuesday, Reuters reported, citing a source familiar with the matter.

EU Council President Charles Michel, who chairs summits of prime ministers and presidents from the 27 EU nations, said via Twitter on Monday that he was calling on Tuesday what will be the second meeting of its kind in two weeks.
"Containing the spread of the virus, providing sufficient medical equipment, boosting research and limiting the economic fallout is key," Michel tweeted.
The EU is urging its member countries to put common health screening procedures in place at their borders to limit the spread of the virus, the Associated Press says, but not to block the transport of important medical equipment.
In Hungary, Prime Minister Viktor Orban announced Monday in Parliament that international coordination about border closures is underway.
