Vedclass · Answer

(B) The human immunodeficiency virus $(HIV)$ is a retrovirus that attacks the immune system.Specifically,it targets and destroys $T$-helper lymphocytes ($CD4^+$ cells).As the infection progresses,the number of $T$-lymphocytes decreases significantly,leading to a weakened immune system.Therefore,the statement that $T$-lymphocytes increase in number is incorrect.Viral $DNA$ is indeed synthesized from viral $RNA$ using the enzyme reverse transcriptase.$ELISA$ (Enzyme-Linked Immunosorbent Assay) is the standard diagnostic test for $AIDS$.Patients with $AIDS$ often experience symptoms like persistent fever,diarrhea,and weight loss due to opportunistic infections.

Which of the following statements is incorrect regarding $AIDS$?
