What characterizes AIDS in relation to the immune system?

• A. It strengthens the immune system
• B. It has no effect on the immune system
• C. It weakens the immune system
• D. It causes the immune system to overreact

Answer: (C)

AIDS, or Acquired Immunodeficiency Syndrome, is primarily characterized by its detrimental effect on the immune system. Specifically, it weakens the immune system, making the body much more susceptible to infections and diseases. This weakening occurs because the Human Immunodeficiency Virus (HIV) attacks and destroys CD4 cells, which are crucial components of the immune response. As the number of these cells declines, the body loses its ability to fight off pathogens, which can lead to opportunistic infections and certain cancers that typically do not affect individuals with a healthy immune system. Understanding this characteristic of AIDS is essential for addressing the treatment and prevention of related health issues.
