22,264 in hospitals, 684,521 quarantined
The Polish health ministry announced on Sunday morning that 22,264 COVID-19 patients were in hospitals nationwide, 1,969 of them on ventilators, with a further 684,521 people quarantined for possible coronavirus exposure.
Meanwhile, 3,142,265 people have now recovered from COVID-19 throughout the country, the health ministry also said.
Poland this month imposed a temporary ban on flights to seven African countries amid concerns over the new, highly contagious strain of the coronavirus, omicron.
In other new COVID-19 restrictions, cultural institutions, churches, sports centres, hotels and restaurants across the country are only allowed to be half full from December 1 to December 17.
The limits do not apply to people vaccinated against the coronavirus.
Health Minister Adam Niedzielski told reporters last week that the fourth wave of the COVID-19 pandemic was expected to reach its height in Poland in early December, with up to 35,000 daily cases.
