Note. Data include persons with a diagnosis of HIV infection regardless of stage of disease at diagnosis.

See Technical Notes for the list of areas that have had laws or regulations requiring confidential name-based HIV infection reporting since at least January 2005.

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 Hispanics/Latinos can be of any race.

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

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

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

f 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.
