A shopper washes her hands using a mobile handwashing machine called WOSH, installed to prevent the spread of the coronavirus disease, in Ginza shopping district in Tokyo, Japan, on Saturday. The machines don’t require connection to running water and don’t use fresh and waste water tanks. Instead they recycle the water through a three-stage process and have a device that cleans smartphones through 20-30 seconds of ultraviolet light exposure while users are washing their hands, since touching a dirty smartphone would otherwise negate their handwashing efforts.Xinhua
