Jet hand dryers spread dangerous bacteria around bathrooms and are significantly less hygienic than traditional paper towels, scientists have found. 科研人员日前发现，喷气式烘手机会在卫生间内传播危险的细菌，卫生程度远低于传统的纸巾。 An international study in hospitals established that modern dryers create an aerosol effect, blasting E. Coli as well as traces of faeces and the bacteria responsible for septicaemia onto surfaces. 一项在医院内进行的国际研究证实，现代烘手机会产生一种雾化效果，将大肠杆菌、微量排泄物和引发败血症的细菌吹到物品表面上。 While the devices can often be activated without being touched, which is supposed to improve hygiene, they are problematic because people fail to properly wash their hands, the experts said. 专家称，虽然这种设备通常可以不用手触摸便自行启动--这本应提高卫生度--但由于人们没有以恰当的方式洗手，这些设备还是会带来问题。 |
