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. When going to the hospital for physical examination, it is difficult to ensure that the instruments and equipment for examination are not used with the patients, and there is bound to be a potential threat of cross-infection caused by disease aggregation.
2. USA: As a health check-up institution, the health check-up population is mainly healthy/sub-healthy. Compared with hospitals, the equipment for health examination is hardly used with patients, thus eliminating iatrogenic infection.
