The combination of Delta and Omicron variants is driving a dangerous tsunami of Covid-19 cases, the World Health Organization (WHO) chief has said.
France reported Europe's highest ever daily figure for the second day in a row, at 208,000 cases.
And the US has reported a record average of 265,427 cases a day over the last week, according to Johns Hopkins.
Denmark, Portugal, the UK and Australia have all also reported record-breaking figures.
Poland reported 794 Covid-related deaths on Wednesday, the highest number in its fourth wave of the pandemic. More than three-quarters of these were unvaccinated people.
Studies suggest that Omicron - which has quickly become dominant in numerous countries - is milder than the Delta variant, but far more contagious. It is believed to be driving the surge in cases, with French health minister Olivier Véran telling reporters he would "no longer speak of a wave when it comes to Omicron" but a "tidal wave".
