Question

At which stage of HIV infection does one usually show symptoms of AIDS?

• A. When the infecting retrovirus enters host cell
• B. When HIV replicates rapidly in helper T-lymphocytes and damages larger number of this
• C. When viral DNA is produced by reverse transcription
• D. Within 15 days of sexual contact with an infected person

Answer 1

The correct option is B

When HIV replicates rapidly in helper T-lymphocytes and damages larger number of this

The causative HIV retrovirus enters helper T-Iymphocytes, replicates and produce progeny viruses, thus reducing the number of helper T- cells which stimulate antibody production by B- cells, thereby showing the primary symptoms like fever, swollen throat, muscle and joint aches.
