I, the subway car is required to regularly disinfect every day, the previous disinfection method, usually only with water mixed with ordinary 84 disinfectant wipe car. But now, the metro company use sterilization stronger, no harm to people, no odor disinfectant for cleaning and disinfection, every day on the floor of the subway car, seats, rings, handrail poles and other key disinfection. This new disinfectant on hepatitis, intestinal infectious diseases, skin infectious diseases, sexually transmitted diseases, AIDS pathogens, etc. has a rapid, long-lasting killing effect, sterilization rate can reach more than 99%.

Two, buses, subways, cabs are very high traffic places, disinfection can be a large reduction in the number of germs, viruses, and disinfection intervals should be the shorter the better. If the bus, cab conditions allow, should also increase the frequency of disinfection. But the role of disinfection is also limited, the main thing is that passengers must pay attention to personal hygiene, if everyone's hands are very clean, then even if the train is not disinfected is not a big problem.
