Abstract：Objective To understand the disinfection effect of entry aircrafts during the SARS-CoV-2 pandemic, and to provide a scientific basis for prevention of respiratory infectious diseases. Methods The air in the aircrafts was disinfected with quaternary ammonium salt disinfectant, aerosol spray was used for spray disinfection at the rate of 20 ml/m3, and the air disinfection effect was monitored by detecting natural bacteria. The surface of objects was disinfected with slow-release chlorine containing disinfectant and sprayed with constant sprays until the surface of objects was wet. Door handles, handrails, and the like were wiped and disinfected, and the disinfection effect of object surface was monitored by indicator bacteria method. Results During the SARS-CoV-2 pandemic at abroad from March to December 2022, 20 out of 157 inbound aircrafts were randomly sampled for disinfection monitoring. The total qualified rates of the material surface and the air were 99.75% and 95.00% respectively. After redisinfection, the unqualified ones detected were found to meet the disinfection requirements. Conclusion During the SARS-CoV-2 pandemic, timely formulating a scientific and standardized disinfection plan for entry aircrafts and implementing disinfection of the air and the object surface according to the plan can effectively cut off the route of SARS-CoV-2 transmission by contacting the air and the object surface of entry aircrafts, which has important practical significance for strictly preventing the SARS-CoV-2 infection imported from overseas.
