a Includes persons with a diagnosis of AIDS, reported from the beginning of the epidemic through 2004. Cumulative total includes 2 persons of unknown sex.
b AIDS developed in 47 adults/adolescents and 3 children after they received blood that had tested negative for HIV antibodies. AIDS developed in 14 additional adults after they received tissue, organs, or artificial insemination from HIV-infected donors. Four of the 14 received tissue or organs from a donor who was negative for HIV antibody at the time of donation.
c Includes 36 adults/adolescents who were exposed to HIV-infected blood, body fluids, or concentrated virus in health care, laboratory, or household settings, as supported by seroconversion, epidemiologic, and/or laboratory evidence. One person was infected after intentional inoculation with HIV-infected blood. For an additional 424 persons who acquired HIV infection perinatally, AIDS was diagnosed after age 12. These 424 persons are tabulated under the adult/adolescent, not the pediatric, transmission category.
d Includes 5 children who were exposed to HIV-infected blood as supported by seroconversion, epidemiologic, and/or laboratory evidence: 1 child was infected after intentional inoculation with HIV-infected blood and 4 children were exposed to HIV-infected blood in a household setting. Of the 187 children, 23 had sexual contact with an adult with or at high risk for HIV infection.
