Question

Quizplus · Accepted Answer

During phase 3 HIV infection, also known as AIDS, the CD4⁺ cell population drops to less than 200 cells per μl of blood. This low level of CD4⁺ cells greatly weakens the immune system and makes the person susceptible to opportunistic infections and cancers. The amount of HIV in the blood also increases to very high levels, but this varies depending on the individual and the stage of their infection. The other choices are incorrect: A is not always true, C is an exaggeration, D is an incomplete description because some people with AIDS may experience symptoms, and E refers to a process that occurs during the acute infection phase.
