Which virus is described as asymptomatic for years and can be transmitted through blood and body fluids?

• A. HIV
• B. Hepatitis B
• C. AIDS
• D. Herpes

Answer: (A)

This question tests how long a virus can be present without symptoms and how it’s spread through blood and body fluids. HIV is known for a long asymptomatic period—people can live for years with HIV before any AIDS-defining illness appears—while still being able to transmit the virus through blood, semen, vaginal fluids, rectal fluids, and breast milk. That combination of a lengthy asymptomatic phase and transmission via blood and body fluids is what makes HIV the best fit for this description. AIDS isn’t a virus itself; it’s the advanced stage of HIV disease. Hepatitis B can also be transmitted through blood and body fluids and can be asymptomatic, but the question’s focus on a long asymptomatic period before transmission points most clearly to HIV. Herpes spreads mainly through close personal contact and skin-to-skin contact, not primarily through blood and body fluids in the way HIV does.
