Today when the practice of wearing a mask is slowly and gradually disappearing among people, 44-year-old Ramdhari Kumar, a street vendor in the old Delhi area selling balloons and toys, makes it a point to cover his nose and mouth while dealing with consumers. He says that buyers feel more confident and freer to interact with him, and there are chances of higher sales. “The pandemic caused a huge loss to us. However, it taught us lessons in good health and hygiene,” Kumar says, as he gives credit to Banega Swasth India (BSI), a campaign run by Dettol, for this behaviour change.
