You absolutely cannot judge HIV infection by symptoms, because HIV has no specific symptoms—and relying on them is completely unreliable.

Fever, fatigue, night sweats, diarrhea, rash… these can all be caused by a cold, lack of sleep, high stress, gastroenteritis, allergies, or many other common conditions. Even doctors cannot make a diagnosis based on symptoms alone—so ordinary people have no way to tell the difference just by self‑observation.
