Rumor. The COVID-19 virus spread from people to people, but not travel on radio waves/mobile networks. The virus spread through respiratory droplets when an infected person coughs, sneezes or speaks. People can also be infected by touching a contaminated surface, then their eyes, mouth or nose.
The major routes of transmission are still through respiratory droplets and direct contact, so it's highly unlikely that recycled subway tickets are contaminated with the virus, according to Feng Luzhao, an analyst from the Chinese Center for Disease Control and Prevention. Wearing a mask and keeping your hands clean are effective ways to prevent viral infections in daily life. Besides, when going out on the subway, people are encouraged to use a personal transportation card or pay for the ticket via an app. After taking public transportation, washing hands is necessary.
