Workplaces are the main source of Covid-19 clusters in France, one of the country’s top coronavirus experts has revealed, insisting that wearing face masks must be made mandatory in all enclosed spaces.

Some 50 percent of 609 coronavirus clusters across France originate from various companies, both medical and non-medical, Eric Caumes, head of infectious diseases at Paris hospital La Pitie-Salpetriere, told Franceinfo radio on Thursday. Some 22 percent of those clusters have been detected in private companies, he added.

“Given that companies have the highest rate of virus infection clusters, we should make the wearing of masks mandatory in all enclosed spaces, including in private companies,” Caumes said.

Moreover, all employers should ask their staff to work from home if possible, he added, explaining that working remotely is the best option to “prevent infection between colleagues.” (RT)
