* Estimates resulted from statistical adjustment that accounted for reporting delays and missing risk-factor information, but not for incomplete reporting. Data include persons with a diagnosis of HIV infection regardless of stage of disease at diagnosis. Values exclude Puerto Rico and the U.S. territories. Because totals are calculated independently of the values of subpopulations, data may not sum to total.
** Heterosexual contact with a person known to have, or to be at high risk for, HIV infection.
*** Includes hemophilia, blood transfusion, perinatal exposure, and risk factor not reported or not identified.
