Based on current information, the novel coronavirus spreads mainly through droplets and contacts. The virus is unlikely to stay on the reusable metro tickets. But to minimize the risk, it is recommended that you pay with your personal transport card or mobile phone. Wash your hands after taking public transport like the metro.
目前,新冠肺炎仍以飞沫和接触传播为主。虽然循环使用的地铁票沾染病毒的概率非常低,但为了避免可能的接触,推荐使用个人公交卡或手机支付,乘坐地铁等交通工具后要及时洗手。
