Which statement best describes the initial presentation of HIV infection?

• A. Acute respiratory distress syndrome
• B. Severe diarrhea requiring hospitalization
• C. Asymptomatic or mononucleosis-like illness
• D. Severe hepatitis

Answer: (C)

Early HIV infection is typically marked by an acute retroviral syndrome that can look like a mono-like illness or be entirely asymptomatic. After exposure, the virus replicates rapidly and often triggers fever, fatigue, sore throat, swollen lymph nodes, rash, and muscle aches within a few weeks. Many people have only mild symptoms or none at all, so the initial presentation is frequently asymptomatic or resembles mononucleosis. This phase is when seroconversion is occurring, and testing may require either antigen or RNA detection before antibodies appear. The other options don’t fit as the initial presentation. Acute respiratory distress syndrome is a severe, acute lung failure not typical of primary HIV infection. Severe diarrhea requiring hospitalization suggests an opportunistic infection or another cause that tends to emerge later in disease or with significant immunosuppression. Severe hepatitis isn’t the hallmark early presentation and would usually point to coinfection or different etiologies.
