In essence, it is impossible for laws and regulations to list the types of diseases through enumeration, which is inexhaustible. It is also impossible to list all the diseases in medicine and then exclude them, which is called good health.
In the strict sense of medicine, as long as people suffer from diseases (including psychological diseases), they are called unhealthy. However, judging from the selection and use of cadres, the requirements are not so strict. It is generally believed that as long as the body does not affect the work and there is no obvious disease, it is considered healthy. For example, hepatitis B virus carriers used to think that they were unhealthy and could not enter the civil service. In fact, hepatitis B virus carriers will not infect diseases and will not affect their work under normal liver function. Therefore, recruiting civil servants is not allowed to check "two and a half", only liver function. That's the reason.
