Positive tests shot up to 147,248 according to figures released Tuesday, 54 percent higher than the previous week, with experts referring to a seventh wave of the virus in Europe.
Borne spoke out after a meeting with senior health officials and the administrative heads of France’s regions.
While it is no longer compulsory to wear masks on public transport, Borne said she was recommending using them in crowded places or confined spaces because of the rise in cases.
She also reminded people to wash their hands frequently, keep enclosed places aired and to check that they were up to date on their vaccinations.
Vulnerable people and anyone aged over 60 already have the right to a vaccine booster.
The second booster appointments have been available since May, but as cases rise the government has been stepping up communication urging those eligible to make an appointment.
As cases rise, appointments for second booster shots have seen a sharp increase.
