HIV Screening RecommendationsQuestion 10/10

A 29-year-old man who has sex with men is newly diagnosed with HIV. The last HIV test he had was approximately 9 years ago and it was negative at that time.  He currently has no HIV-related symptoms, but initial laboratory studies revealed a CD4 count of 165 cells/mm3.

Based on CDC data from the year 2022, approximately what percentage of persons have an AIDS diagnosis at the time they are diagnosed with HIV?

Data from 45 states for new HIV diagnoses (age ≥13 years). Stage 0 = Positive HIV test <6 months after a negative HIV test; Stage 1 = CD4 count >500 cells/mm<sup>3</sup>; Stage 2 = CD4 count 200-499 cells/mm<sup>3</sup>; Stage 3 (AIDS) = CD4 count <200 cells/mm<sup>3</sup>, CD4% <14, or AIDS-defining clinical condition
