⁣Disinfection tunnels have been installed this week at the entrance of a supermarket in Ajaccio on the French island of Corsica. Footage from November 12 shows shoppers passing through a blue-lit tunnel diffusing the disinfectant. At a cost of 9,500 euros, the manufacturer Corse Chimie Industrie promises to fight coronavirus through triple disinfection by ultrasound, ultraviolet light, and misting a hypochlorous solution.
