HIV and AIDS Problem Set

Problem 1: HIV+ patient and AIDS


Which HIV+ patient is most likely to have AIDS?

A. A person who engaged in high-risk sexual behavior three months ago
B. A person who engaged in high-risk sexual behavior ten years ago
An HIV infected person develops AIDS when their helper T cell number are drastically reduced. The body is initially able to replace destroyed helper T cells, but after years (ten years on average), HIV overwhelms the body's ability to make helper T cells, and the person develops AIDS.
C. A recently infected person whose drug therapies include reverse transcription inhibitors and protease inhibitors
D. A person who has an almost normal number of helper T cells detected in her blood sample
