The risk of contracting the new coronavirus in cabs is slightly lower than that of trains and planes, but passengers still need to protect themselves by taking the following measures: 1) open the door for ventilation before riding; 2) disinfect the seat and the location where hands may touch with disinfectant paper towels; 3) wear a mask throughout the journey, and also ask the driver to wear a mask; 4) pay attention to hand hygiene after getting off, and use alcohol-containing quick-drying hand Disinfectant. If there are visible contaminants on the hands, they should be washed under running water with hand sanitizer and then disinfected.
