Which of the following is NOT considered an early sign of HIV/AIDS?

Fatigue and vague abdominal pain can be nonspecific symptoms that occur in a variety of conditions, making them less distinctive early indicators of HIV/AIDS. In contrast, fever, weight loss, and night sweats are considered more classic early signs of HIV infection.

Fever often presents as a result of the body's immune response to the virus, serving as a common initial symptom. Weight loss can occur due to the body's increased caloric needs and a decreased ability to metabolize and absorb nutrients effectively. Night sweats are also frequently reported as an early symptom, indicating the body's ongoing struggle against the viral infection.

When assessing for early signs of HIV/AIDS, more specific symptoms like fever, night sweats, and significant weight loss tend to be prioritized, while fatigue and vague abdominal pain may not raise immediate concern in the early stages of the infection.
