Poland's daily Covid-19 cases have risen by around 70 per cent in the past week to over 2,000, a government official said, warning the country that a fourth wave of the outbreak is gathering pace.

“Today's data is a very fast flashing red light,” Waldemar Kraska, a deputy health minister, told public broadcaster Polskie Radio 1, adding that there were 2,085 cases reported today.

“This is the last moment when we should get vaccinated, because the fourth wave is definitely accelerating, and in those regions where the number of vaccinated people is the lowest.”
