Which of the following is a viral disease that primarily attacks the immune system, specifically the CD4+ T helper cells? MCQ with Answer and Explanation

Human Immunodeficiency Virus (HIV), the causative agent of Acquired Immunodeficiency Syndrome (AIDS), is a retrovirus that specifically targets and destroys CD4+ T helper cells, which are crucial for coordinating the adaptive immune response. As the CD4+ count drops, the immune system becomes severely compromised, leading to opportunistic infections and certain cancers. Hepatitis B targets the liver, Herpes causes lesions, and Influenza targets the respiratory tract.
