It will be appreciated that hospital infectious diseases exist in relatively complex, high-risk environments, with hospital workers having a higher chance of contracting the infectious disease than non-medical workers. Medical workers deal with different disease types treated in the hospital every day, and partial patients are not excluded to carry pathogenic viruses, which brings great challenges to the medical workers. When the doctor goes out of the clinic, the patient comes from different places and different disease types. However, the procedures of seeing and treating diseases in hospitals are almost the same, and generally the processes of looking at, smelling, asking and cutting are performed. The very important step is to know the disease condition by close contact between the doctor and the patient.
