At which stage of HIV infection does one usually shows symptoms of AIDS?
When viral DNA is produced by reverse transcriptase
When HIV replicates rapidly in helper T-lymphocytes and damages large number of these
With 15 days of sexual contact with an infected person
When the infecting retrovirus enters host cells
Solution
HIV enters into T-lymphocytes, replicates and produces progeny viruses. The progeny viruses released in the blood other helper T-lymphocytes. This is repeated leading to a progressive decrease in the number of T-lymphocytes in the body of the infected person. During this period, the person suffers from bouts of fever, diarrhoea and weight loss. The person starts suffering from infections.
