What are the three categories of HIV?

@pyer The CDC classifies HIV infection into 3 categories, as follows :
Category A: Asymptomatic HIV infection without a history of symptoms or AIDS-defining conditions
Category B: HIV infection with symptoms that are directly attributable to HIV infection (or a defect in T-cell–mediated immunity) or that are complicated by HIV infection
Category C : HIV infection with AIDS-defining opportunistic infections
These 3 categories are further subdivided on the basis of the CD4+ T-cell count, as follows:
500/µL: Categories A1, B1, C1
200-400/µL: Categories A2, B2, C2
< 200/µL: Categories A3, B3, C3
