People have some misunderstandings about health certificates:
Holding a "health certificate" indicates good health. The health certificate stipulates that the holder shall have a health examination once a year, and the personnel are mobile, while the examination of the health certificate is relatively static. Some licensees are infected with diseases after the exam, but they still hold qualified health certificates before the next exam. Many diseases are hidden and latent, and carriers themselves do not feel symptoms; Some people are afraid that failing the examination will mean being laid off, deliberately avoiding concealment, and leading patients or carriers with health certificates to continue working.
