Stage I HIV infection typically occurs within how many weeks after initial infection?

In the earliest stage after HIV infection, the virus multiplies rapidly and most people develop noticeable symptoms within about two to four weeks. This is the acute or primary phase, often presenting as flu-like illness with fever, fatigue, sore throat, swollen glands, or rash. Because antibodies to HIV may not yet be present at this point, antibody tests can be negative or inconclusive, so tests that detect viral RNA or p24 antigen are often used to diagnose infection early. The other time windows describe later stages after the acute window, when the infection has progressed beyond this initial period.
