What are the three categories of HIV?

[Yatharth]

@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
