College students are not examined for AIDS, which is not part of the routine checkup program. Routine checkups include routine blood tests, urine tests, chest X-ray, electrocardiogram, blood pressure and aminotransferase tests. If you suspect that you are infected with AIDS, you need to go to a regular hospital for an HIV test. If AIDS is diagnosed, it is important to intervene as soon as possible to control the condition. At the same time, college students also need to understand the transmission of HIV, which is through sexual transmission, blood transmission, and vertical transmission from mother to child, so that they can do a good job of self-protection to prevent the spread of HIV.
