Signs and symptoms of HIV/AIDS

Common card · No. 211253

The signs and symptoms of HIV infection vary across the three stages of infection: acute infection, latency, and AIDS. Acute infection (also known as primary infection) begins soon after exposure and typically lasts 2–4 weeks and may include symptoms such as fever, swollen lymph nodes, inflammation of the throat, rash, muscle pain, malaise, and mouth and esophageal sores. This is followed by the latency stage, which involves few or no symptoms, and can last anywhere from two weeks to twenty years or more. The final stage, AIDS, is defined by low CD4+ T cell counts (fewer than 200 per μL), various opportunistic infections, cancers, and other conditions.
