Up to 10% of France’s newly-registered coronavirus cases are the Delta variant, government spokesman Gabriel Attal said on Wednesday.

“There are concerns about the worldwide spread of the new coronavirus strain Delta found in India, which is considered to be more contagious… In France, the percentage of infection with this variant is 9-10%,” Attal said at a briefing on Wednesday.

The Delta strain of the coronavirus was first identified in India in December 2020.

The World Health Organization included the Delta variant in its list of the so-called variants of concern as it became prevalent and caused a resurgence of coronavirus cases in some countries.
