Paris, Lyon and Lille approaching the 'maximum alert zone' threshold
The incidence rates of the novel coronavirus in Paris, Lyon and Lille have exceeded the threshold of 250 new cases per 100,000 inhabitants set by the government.
In France, a region can be placed on maximum alert when the incidence rate of the virus -- the number of new positive cases -- is greater than 250 per 100,000 inhabitants over the last seven days in the general population and over 100 for people over 60. More than 30% of intensive care beds must also be occupied by COVID-19 patients.
Paris, Lyon and Lille have now reached several of these milestones meaning the cities could be placed on "maximum alert" and have new government restrictions placed on them.
As of Tuesday, France has reported 590,021 cases of coronavirus and 31,908 deaths.
France is attempting to revive its economy while simultaneously trying to curb a steady climb in infections which spread during the summer months.
