The physical examination crowd is different
1. Hospital: the place where patients gather. It is mainly responsible for the examination and diagnosis of patients and people suspected of having diseases. Going to the hospital for physical examination, it is difficult to share the instruments and equipment with patients, and it is inevitable that there will be a potential threat of cross-infection caused by disease aggregation.
2. USA: As a physical examination institution, the physical examination population is mainly healthy/sub-healthy. Compared with hospitals, physical examination equipment is hardly shared with patients, which eliminates iatrogenic infection.
