PARIS: France has entered a fourth wave of the Covid-19 epidemic, which is spreading at 'lightning' speed, said government spokesman Gabriel Attal on Monday evening while announcing tough sanctions on noncompliance with the health pass rules. 'We are seeing a wave faster than all the previous ones,' Attal told a press conference, noting that the incidence rate has increased by nearly 125 percent in one week, 'an increase so strong, so sudden that we had never known since the beginning of the epidemic in our country.' 'For several days we have crossed the threshold of 10,000 positive cases every day. This virus contaminates at lightning speed,' he said.
