...Of these, an estimated 41,400 incident HIV infections were attributed to sexual transmission (26,900 to male-to-male sexual contact and 14,500 to heterosexual contact).(29) Among black/African American, Hispanic/Latino, and white males, an estimated 30,100 incident HIV infections were attributed to male-to-male sexual contact and heterosexual contact....

...HIV incidence was estimated using a stratified extrapolation approach based on concepts borrowed from sample survey methodology; details are described elsewhere.(29,31,32) Incidence estimates were adjusted to account for reporting delay, but not incomplete reporting....

...Overall, these 3 racial/ethnic groups accounted for 96% (45,700/47,800) of all incident HIV infections.(29) Among persons aged 13 to 29 years, an estimated 18,600 incident HIV infections occurred in 2008; we were unable to stratify by sex or estimate infections attributed to sexual transmission for this age group....

...New diagnoses were classified as of recent or long-standing duration based on STARHS results; information on history of HIV testing and antiretroviral use was used to classify individuals as those testing HIV positive on their first HIV test and those testing negative for HIV before HIV diagnosis.(29) Multiple imputation was used to assign a transmission category to those reported without risk information,(30) and imputed transmission category values were used to impute missing STARHS results and testing history information....

...Estimated incidence within the 18 jurisdictions was extrapolated to the remaining US areas and the District of Columbia to obtain a population-based national HIV incidence estimate.(29) An estimated 47,800 incident HIV infections occurred in United States in 2008....

...We also calculated the estimated annual percentage change (EAPC) in the estimated number of new HIV infections by fitting a logistic regression model to the natural logarithm of the incidence estimate using calendar year as the regressor [12]....

...The increase in HIV incidence in young MSM is in line with the increase seen in new diagnoses in MSM in recent years in the United States [16] and internationally [17] as well as with increases in HIV incidence seen in the United States using an extended back-calculation model [4] and with international trends in incidence in MSM [18–19]....
