Which disease is transmitted through blood products and sexual contact and severely weakens the immune system?

• A. AIDS
• B. Bacteriology
• C. Cilia
• D. Cocci

Answer: (A)

This question tests understanding of how a virus can weaken the immune system and how it’s transmitted. HIV is the virus that attacks the body's CD4+ T cells, gradually compromising the immune system. When the immune system becomes severely impaired, the condition is diagnosed as AIDS. HIV can be transmitted through blood products and sexual contact, among other routes. The other options aren’t diseases or don’t describe a virus that targets the immune system: one is a field of study, another is a cellular structure, and another is a type of bacteria. Therefore, AIDS best fits the description.
