           of COVID-19 pandemic control. Objective To understand the awareness and skills of correctly donning and doffing PPE in
           SARS-CoV-2 containment workers from a mobile cabin hospital. Methods By use of cluster sampling,460 SARS-CoV-2
           containment workers were selected from the Fourth Branch of Shanghai Mobile Cabin Hospital located in the National Exhibition
           and Convention Center(Shanghai),from April 10 to May 10,2022. Their awareness and skills of correctly donning and doffing
           PPE were assessed using an online survey with a self-developed questionnaire named Awareness of Correctly Donning and Doffing
           Personal Protective Equipment,and using an onsite performance assessment with a self-developed questionnaire named Skills
           of Correctly Donning and Doffing Personal Protective Equipment,respectively. Results The survey obtained a response rate
           of 83.5%(384/460). According to the survey,both doctors and nurses had significantly higher average scores with regards to
           the operations at the first donning area,second donning area,front doffing area and first doffing area,second doffing area,
           and hand hygiene disinfection than public security officers and fire fighters(P<0.05). All of the 460 cases completed the onsite
           performance assessment. Both doctors and nurses obtained lower average scores in terms of completing the operations at the first
           donning area,and donning steps in clean area into contaminated area than public security officers and fire fighters(P<0.05).
           Doctors had much lower average score for completing the operations at the first donning area than nurses(P<0.05). Conclusion
            There were significant differences in the levels of awareness and skills of correctly donning and doffing PPE in SARS-CoV-2
           containment workers by occupation. Targeted and focused trainings and supervisions should be carried out to improve the
           mismatching between the levels of awareness and skills.
