If you have engaged in high-risk behaviors or are experiencing symptoms similar to those of AIDS, you should not speculate about whether you have contracted HIV. The only approach is to go to the hospital for testing. Generally, after the window period has passed, you should go to the hospital for a screening test. If the screening test is positive, further tests should be conducted at the disease control center to confirm the diagnosis. Only through this process can it be determined whether you have AIDS or not.
