UT High School Health 1 Practice Exam

Which term refers to the late stage of HIV?

Hepatitis Tuberculosis Herpes AIDS

Correct Answer:

AIDS

Explanation:

Understanding how HIV progresses helps explain why the late stage is called AIDS. HIV damages the immune system by targeting CD4 T cells. When those cells drop to very low levels or the body develops opportunistic infections or certain cancers, the immune system is too weak to fight off illnesses, and this advanced stage is diagnosed as AIDS. The other terms listed refer to distinct infections or diseases that can occur in people with HIV or are unrelated conditions (hepatitis affects the liver; tuberculosis is a bacterial infection; herpes is a viral infection), but they are not the label for the final stage of HIV.
