French supermarkets have promised to put millions of masks on sale to protect against Covid-19. Some health professionals are asking for an explanation about these deliveries after weeks of shortages and rationing.

The controversy keeps growing: On May 4, millions of single-use masks went on sale in France in supermarket chains. The announcement by Agnès Pannier-Runacher, secretary of state to the minister of the economy and finance, provoked the indignation of many health professionals, who have been calling for more masks for weeks.
