To suspect HIV/AIDS in a young individual, which one among the following symptoms is mostly associated with ?

Chronic or persistent diarrhoea is a hallmark clinical manifestation of HIV/AIDS, particularly in young individuals and children [t1][t2]. It is defined as loose or watery stools lasting 14 days or more and is often the presenting symptom in approximately a quarter of new HIV diagnoses [t1][t2]. In advanced stages of the disease, gastrointestinal involvement is nearly universal, with over 90% of patients experiencing diarrheal syndrome due to opportunistic infections or the virus itself [t3]. While other symptoms like headache or anemia can occur, they are often non-specific or associated with secondary complications [t6][t7]. Chronic diarrhoea is specifically highlighted as a major factor for morbidity and a primary indicator for suspecting underlying immunodeficiency in clinical settings [t1][t3]. Therefore, in a young individual, persistent gastrointestinal distress is a significant clinical marker for HIV screening.
