Choose the wrong statement regarding AIDS ?

AIDS stands for Acquired Immuno Deficiency Syndrome. This means deficiency of immune system, acquired during the lifetime of an individual indicating that it is not a congenital disease.

AIDS is caused by the Human Immuno deficiency Virus (HIV), a member of a group of viruses called retrovirus, which have an envelope enclosing the RNA genome.

HIV enters into helper T-lymphocytes (TH ), replicates and produce progeny viruses. The progeny viruses released in the blood attack other helper T-lymphocytes. This is repeated leading to a progressive decrease in the number of helper T -lymphocytes in the body of the infected person. During this period, the person suffers from bouts of fever, diarrhoea and weight loss.
