HIV / AIDS Incidence Falls in Blacks And Injection Drug Users, CDC Says

By MIRIAM TUCKER, Senior Writer The annual incidence of HIV/AIDS among African Americans dropped significantly between 2001 and 2004, the Centers for Disease Control and Prevention reported.

As a result of advances in treatment with highly active antiretroviral therapy, individuals with HIV infection are living longer than before, and progression to AIDS has declined sharply. AIDS surveillance no longer provides an accurate estimate of HIV infection rates, so the CDC now recommends that all states and territories adopt confidential name based surveillance systems to report HIV infection.

Data from 33 state and local health departments with name-based reporting indicate that the incidence of HIV infection among blacks declined about 5% per year, from 88.7/ 100,000 in 2001 to 76.3 in 100,000 in 2004. Nonetheless, the HIV/AIDS rate among blacks in 2004 was still 8.4 times higher than that of whites, the CDC said (MMWR 2005;54:1149-53).

In addition to the statistically significant decline among blacks, there was a significant 9.1% annual drop among injection drug users. Overall, the average annual rate of HIV/AIDS diagnoses dropped in significantly, from 22.8/100,000 in 2001 to 20.7/100,000 in 2004.

An estimated 157,252 individuals were diagnosed with HIV/AIDS in the 33 states during 2001-2004, of whom 71% were male. Blacks accounted for 51 % of those diagnosed with HIV/AIDS, whites 29%, Hispanics 18% and Asian/Pacific Islanders 1%.

Among males, the route of HIV infection was male-to-male contact for 61 %, high-risk heterosexual contact in 17%, and injection drug use in 16%. For females, on the other hand, the majority (76%) were exposed through high-risk heterosexual contact and 21 % through injection drug use. Among black males, approximately one-fourth of HIV transmission occurred via high-risk hetero sexual contact, the CDC noted.

A significant 9% annual increase in HIV/AIDS diagnosis rates occurred among Asian/ Pacific Islanders, from 5.6/100,000 in 2001 to 7.2/100,000 in 2004, although this group continues to racial/ethnic populations.
