a Estimated numbers resulted from statistical adjustment that accounted for reporting delays and missing risk-factor information, but not for incomplete reporting. Rates are per 100,000 population. Rates not calculated by transmission category because of the lack of denominator data.

b From the beginning of the epidemic through 2008.

c Includes Asian/Pacific Islander legacy cases (see Technical Notes).

d Hispanics/Latinos can be of any race.

e Heterosexual contact with a person known to have, or to be at high risk for, HIV infection.

f Includes hemophilia, blood transfusion, perinatal exposure, and risk factor not reported or not identified.

g Includes hemophilia, blood transfusion, and risk factor not reported or not identified.

h Because column totals for estimated numbers were calculated independently of the values for the subpopulations, the values in each column may not sum to the column total.

i Includes persons of unknown race/ethnicity.
