As Cases Rise, France Contemplates Second Wave of COVID-19

The southern French cities of Nice and Marseille have higher rates of COVID-19 spread than other parts of the country. The spread of infection is measured by the scientific R0, pronounced “R not.” R0 measures, on average, how many new people one person carrying the virus will infect. “We must remain vigilant,” Veran said. On Monday, France also made masks mandatory in all public spaces, including restaurants, shops, and other businesses. Previously, business owners could decide whether their patrons were required to wear face coverings.
