A second wave of the coronavirus pandemic could hit France in November, a government adviser told local media, as the city of Marseille tightened restrictions to fight the outbreak.

“There are fears of a second wave in November,” Professor Jean-François Delfraissy, who heads the scientific council that advises the government on the pandemic, told France 2 television.

France has the seventh-highest Covid-19 death toll in the world, and the government is monitoring the figures closely to see if fresh restrictions or lockdown are needed.
