Table 3. Estimated numbers and rates (per 100,000 population) of new HIV infections in adults and adolescents, 2006—50 states and the District of Columbia
|American Indian/Alaska Native||150||<1||15.5||130||1||12.8||290||1||14.6|
|Age at HIV infection (yr)|
|Male-to-male sexual contact||28,720||72||—||—||—||—||28,700||53||—|
|Injection drug use||3,750||9||—||2,860||20||—||6,600||12||—|
|Male-to-male sexual contact and injection drug use||2,100||5||—||—||—||—||2,100||4||—|
|High-risk heterosexual contactd||5,250||13||—||11,550||80||—||16,800||31||—|
Note. Data have been adjusted for reporting delays and redistribution of cases in persons initially reported without risk-factor information, but not for incomplete reporting. To reflect the uncertainty inherent in statistical estimates, the estimates were rounded: in the table cells, the estimates were rounded to the nearest 10 (rounding to the nearest 100 would have resulted in significant rounding error); in the column and row totals, the estimates were rounded to the nearest 100.
a Because HIV incidence estimates are estimates for 2006, race/ethnicity categories in this table are the categories used in previous surveillance reports and are thus not consistent with the race/ethnicity categories in other tables in this report.
b Hispanics/Latinos can be of any race.
c Values do not include American Indians/Alaska Natives or Asians/Pacific Islanders because small numbers in these groups precluded further stratification on transmission category.
d Heterosexual contact with a person known to have, or to be at high risk for, HIV infection.
e Includes persons of unknown race or multiple races and persons with hemophilia, blood transfusion, and perinatal transmission. Because column totals were calculated independently of the values for the subpopulations, the values in each comumn may not sum to the column total.
