Hungary and Poland are the latest countries to see record daily coronavirus cases, as Europe grapples with a second wave.
Poland saw new cases jump by 21,897 on Saturday, and Hungary saw a record daily increase of 3,908.
Meanwhile Austria's chancellor announced new lockdown measures including a curfew from 20:00 to 06:00.
Slovakia is testing everyone over the age of 10 to try to stop the spread of the disease there.
The project to test four million people in the country, where infections have soared, is expected to last over two weekends.
What's the situation in central Europe?
Much of Europe is battling with soaring infection rates, with several countries reinstating lockdowns or partial lockdowns to try to stem the wave.
Poland saw cases go up for a fifth day in a row, with Covid-19 patients occupying 16,144 hospital beds - 1,305 of them on ventilators - according to the Polish health ministry. There were 280 new deaths.
The rise comes as protesters against last week's near-total ban on abortion continue to defy government calls to stay at home due to rising infections.
The country already has the highest level of restrictions to date, with public gatherings banned, most schools closed and restaurants and cafes only offering take-away service.
Last week, Polish President Andrzej Duda, 48, tested positive for the virus, but experienced no symptoms.
As of Saturday, Poland had 340,834 total cases, with 5,351 deaths according to the European Centre for Disease Prevention and Control.
Deaths from Covid-19 in Hungary rose by 51, bringing the total to 1,750, the government said on Saturday.
It also said the number of Covid patients in hospital had exceeded 4,000 for the first time.
Hungary has yet to impose restrictions on mass events, with schools and shops remaining open and football matches operating throughout the pandemic.
However, Prime Minister Viktor Orban said in a radio interview on Friday that authorities would hand out fines to anyone failing to wear a mask where required.
As of Saturday, Hungary had 71,413 total cases, according to the European Centre for Disease Prevention and Control.
In Austria, Chancellor Sebastian Kurz announced new restrictions including a curfew from 20:00 to 06:00 and the closure of cafes and restaurants except for takeaway service.
He said that shops would remain open.
The restrictions, which will come into force on Tuesday, comes as infections approach a level which officials say will stretch the country's hospitals beyond capacity.
Austria saw 5,349 cases on Saturday, slightly down from Friday's record high of 5,627.
What's happening elsewhere in Europe?

Belgium has announced a return to a national lockdown from Monday, as latest coronavirus figures show it has the highest infection rate in Europe. It means non-essential shops and businesses offering personal services like hair salons will be closed until mid-December. The country has more than half of its 2,000 intensive care unit beds already occupied by Covid-19 patients
France last week entered into a new national lockdown that will last a month, with schools and workplaces remaining open but people requiring permits to leave home.
