    ErrataThe June 2007 revision of the 2005 HIV/AIDS Surveillance Report includes revised and corrected data on estimated AIDS cases for the period 2001 to 2005. Errors in the numbers of estimated AIDS cases included in the original version of the report are corrected in the Commentary, Tables 1–6 and 8–12, Figure 1, and Maps 1 and 2 of the revised report. The errors did not affect reported cases of HIV or AIDS. Further information on the error made in the estimation of AIDS cases for 2001 to 2005 and the corrections made can be found at http://www.cdc.gov/hiv/datarevision.htm

    Commentary: The HIV/AIDS epidemic was first recognized in the United States in 1981. Since that time, all states and U.S. dependent areas have conducted AIDS surveillance using a standardized, confidential name-based reporting system. Since 1985, many states and U.S. dependent areas have also implemented HIV case reporting as part of their comprehensive HIV/AIDS surveillance programs. This report presents estimated numbers of cases of HIV/AIDS (cases of HIV infection, regardless whether they have progressed to AIDS) from the 37 areas (33 states and 4 U.S. dependent areas) that have had confidential name-based HIV infection reporting long enough (i.e., since at least 2001) for data collection to stabilize and for adjustment of the data to monitor trends. According to the number of reported AIDS cases, these 33 states represent approximately 63% of the epidemic in the United States. From 2001 through 2005, the total number of new cases of HIV/AIDS in the 33 states decreased slightly; however, HIV/AIDS prevalence (i.e., the number of persons living with HIV/AIDS) increased during this time. At the end of 2005, an estimated 475,220 persons in the 33 states had been given a diagnosis and were living with HIV/AIDS. The figure on the cover depicts the estimated number of new cases of HIV/AIDS from 2001 through 2005, by race/ethnicity, for adults and adolescents residing in the 33 states.

    Surveillance data on HIV infections provide a more complete picture of the epidemic and the need for prevention and care services than does the picture provided by AIDS data alone. However, the number of new HIV diagnoses does not necessarily reflect trends in HIV incidence (i.e., new infections) because some persons were infected recently and others were infected some time in the past. One method for estimating HIV incidence is to apply the serologic testing algorithm for recent HIV seroconversion (STARHS) to the serum specimens from which the diagnosis of HIV infection was made. A total of 34 areas are using this method to estimate population-based HIV incidence: 5 areas were funded in FY 2002 to pilot this method, 19 areas were funded in FY 2003, another 9 areas were funded in FY 2004, and 1 additional area was funded in FY 2005. The monitoring of HIV incidence is critical to evaluate progress made towards CDC’s goal of reducing the number of new HIV infections in the United States and in allocating resources and evaluating prevention program effectiveness.

    The 2005 HIV/AIDS Surveillance Report is organized in 5 sections: (1) cases of HIV/AIDS and AIDS, (2) deaths of persons with AIDS, (3) persons living with HIV/AIDS, AIDS, or HIV infection (not AIDS), (4) length of survival after AIDS diagnosis, and (5) reports of cases of HIV/AIDS, AIDS, and HIV infection (not AIDS). In Sections 1–3, we present point estimates of case counts that have been adjusted for reporting delays and for redistribution of cases in persons initially reported without an identified risk factor. CDC routinely adjusts data for the presentation of trends in the epidemic. Data to estimate the number of cases of HIV/AIDS or AIDS; the number of persons living with HIV/AIDS, AIDS, or HIV infection (not AIDS); and the number of deaths among persons with AIDS have been statistically adjusted to correct for delays in the reporting of cases and deaths.

    To assess trends in cases, deaths, or prevalence, it is preferable to use adjusted data, presented by year of diagnosis instead of year of report, to eliminate artifacts of reporting in the surveillance system. Therefore, for trends, the reader is encouraged to use the tables in Sections 1–3 that present trends by year of diagnosis, year of death, or year-end prevalence. Section 4 presents estimates of survival for persons whose AIDS diagnosis was made during 2001 (Table 13) and for persons whose diagnosis was made during 1997–2004 (Figures 2–4). Proportions of persons who survived for various lengths of time after diagnosis are presented by year of diagnosis, age group, race/ethnicity, and HIV transmission category.

    Finally, Section 5 presents reports of cases of HIV infection (not AIDS) and cases of AIDS reported through 2005. The areas included in tabulations of reported cases of HIV infection (not AIDS) are based on the date that confidential name-based HIV infection reporting was implemented. For Tables 16, 18, 20, and 22, we used data from 43 areas to describe reports of HIV infection. These data have not been adjusted for delays in reporting and are presented by year of report to CDC. Tables that present cases by year of report represent the most up-to-date information reported to CDC; however, cases by year of report do not represent incident cases, the most recent diagnoses, trends, or deaths.
