Where does the AIDS virus infect?
Correct answer: C. Leukocytes
- A. RBCs
- B. Platelets
- C. Leukocytes
- D. None of these
Explanation
The human immunodeficiency virus (HIV) infects leukocytes, also known as white blood cells. These cells are part of the body's immune system and help fight infection. HIV targets a specific type of leukocyte called a CD4+ T cell. CD4+ T cells help the body fight infection by signaling other immune cells to attack the invading organism.
