Which one of the following statements is correct with respect to AIDS?
A
The causative HIV retrovirus enters helper T-lymphocytes thus reducing their numbers
B
The HIV can be transmitted through eating food together with an infected person
C
Drug addicts are least susceptible to HIV infection
D
AIDS patients are being fully cured cent per cent with proper care and nutrition
Detailed Solution
HIV is a retrovirus. After entering the body it multiplies in macrophages and then enters helper T-lymphocytes, replicates in them and produces progeny viruses that attack other helper T-cells. This leads to a progressive decrease in the number of helper T-lymphocytes. This statement is correct.
HIV spreads only through body fluids: sexual contact, contaminated blood, shared needles and from mother to child; it does not spread by touch or by eating food together.
Drug addicts who share needles are at high risk, not least susceptible.
There is no cure for AIDS; anti-retroviral drugs can only prolong the life of the patient.
Hence the correct statement is that HIV enters helper T-lymphocytes and reduces their numbers.
