Q. Which one of the following statements is correct with respect to AIDS?
A) The HIV can be transmitted through eating food together with an infected person
B) Drug addicts are least susceptible to HIV infection
C) AIDS patients are being fully cured cent per cent with proper care and nutrition
D) The causative HIV retrovirus enters helper T-lymphocytes thus, reducing their numbers
Explanation
In AIDS patients, the virus attacks on $CD_{4} +$ T-cells (helper T-lymphocytes responsible for the coordination of the entire immune system), infecting and killing them until none are left. Without these crucial immune system cells, the body cannot mould a defence against invading bacteria or viruses.
