1 These numbers do not represent actual AIDS cases. Rather, these numbers are point estimates adjusted for delays in the reporting of AIDS cases and for redistribution of cases initially reported with no identified risk, but not adjusted for incomplete reporting of cases. See Technical Notes.
2 Statistical estimates for AIDS incidence in 2001 among persons exposed to HIV through hemophilia/coagulation disorder or receipt of blood transfusion, blood components, or tissue are not presented, but are included in the exposure category “other.” The relatively small number of AIDS cases in these categories in recent years does not provide information that results in reliable annual estimates of incidence (* = data not available); only cumulative estimates are presented. CDC is evaluating and revising the algorithm for estimating AIDS incidence among persons infected in the early 1980's through these exposure categories.
3 For 2001, estimates of “other” include cases exposed through hemophilia/coagulation disorder and receipt of blood transfusion, blood components, or tissue.
