Diagnosis of AIDS requires a combination of epidemiologic history, clinical manifestations, and laboratory tests, and is confirmed by positive results of HIV antibody screening and confirmatory tests.
The main modes of transmission of AIDS include sexual, blood and mother-to-child transmission, so the epidemiologic history includes a history of unsafe sex, intravenous drug use, importation of blood from AIDS patients, and children born to HIV-positive patients.
AIDS can be categorized into acute, asymptomatic, and AIDS phases, with different clinical manifestations in each phase. Symptoms in the acute phase include fever, headache, nausea, muscle pain, skin rash, etc. The asymptomatic phase can have no obvious clinical manifestations. The main manifestations of the AIDS phase are persistent fever, night sweats, diarrhea, weight loss, and various opportunistic infections and tumors.
The more specific tests for AIDS are CD4+ T-lymphocytopenia, positive HIV-1/HIV-2 antibody test, and the antibody test needs to go through two steps: screening test and confirmatory test, and both results are positive to confirm the diagnosis.
If you suspect HIV infection, please go to a regular hospital for examination in time.
