Hehe, if you ask this question, it may not be the answer. Because the exam is mainly about reading books on the subjects you take. Different books have different views on this issue.
For example, diseases will be listed: diabetes, hypertension, hyperlipidemia, cancer and so on.
People who talk about living habits will let out smoking, drinking, staying up late, insomnia and so on.
Microbiologists can talk about various bacteria, viruses and fungi.
So it depends on what your problem is.
Oh, in that case, you fill in AIDS, diabetes, tumor and hypertension.
However, what puzzles me is that although AIDS is called the killer of the century, the incidence rate is not very high. It is far less than the other three, but it is the most serious, even more serious than the tumor. Health killers in disease assessment are generally looking for the highest incidence. Therefore, if it is not AIDS, it should be combined with coronary heart disease. If you are sure you have AIDS, then don't add it.
