Abstract：Objective To evaluate and analyze the surface disinfection on site of railway passenger train,so as to provide reference for optimizing train disinfection.Methods Passenger trains were randomly selected at different levels to evaluate the process and effect of the surface disinfection on site,and made statistical analysis using SPSS 24.0.The Chi-square test and Fisher's exact test were used for multi-group comparison.Results A total of 6 passenger trains were selected to basically meet the requirements in the disinfection plan,disinfection products,disinfection procedures and personal protection.There were mainly problems such as weak awareness of personal protection,and insufficient specific control of individual key points.A total of 293 pairs of samples were collected before and after disinfection,with the total qualified rate of 90.10％.The qualified rate of disinfection in the field guidance group was higher than that in the control group(x2=8.96,P＜0.01).The low qualified rate of the EMU train were faucet(75.00％),and door handle(83.33％).The low qualified rate of ordinary air conditioning train were drinking water switch(75.00％),ladder(83.33％),faucet(85.71％)and luggage rack(87.50％).Conclusion The overall disinfection of passenger trains in the railway area is good and attention should be paid to high-frequency contact parts such as faucets and drinking water switches and difficult disinfection parts such as climbing ladders and luggage racks.Strengthening the on-site guidance of train disinfection personnel is conducive to improving the on-site disinfection effect.
