One year without symptoms can not completely rule out AIDS, AIDS is mainly ruled out through the AIDS antibody test, clinical symptoms alone can not be completely ruled out, because when infected with HIV, sometimes there are no typical clinical symptoms, or the symptoms are relatively mild and unnoticeable, only a part of the people in the 2-4 weeks after the infection of the HIV virus, there may be symptoms of acute infection, the main symptom is fever, The main symptoms are fever, enlarged lymph nodes, sometimes accompanied by nausea, vomiting, night sweats, diarrhea and other symptoms, the symptoms can usually last for 1-3 weeks, but some people have very mild symptoms, which are not noticed and are not taken seriously, or there are no symptoms at all, so the lack of symptoms does not exclude HIV infection. To diagnose HIV infection, you need to have an HIV antibody test, which can be done 2-4 weeks after infection. If the antibody test is positive, you can then have a confirmatory test. If the antibody test is positive, then a confirmatory test can be performed. If the confirmatory test is positive, then the diagnosis of HIV infection can be confirmed.
