Post-migration HIV acquisition among african immigrants in the U.S.

BACKGROUND: African immigrants in the U.S. are more likely to have a late HIV diagnosis than U.S.-born people, potentially leading to onward transmission. We sought to determine the proportion of African-born people living with HIV (APLWH) who (1) had tested HIV negative prior to diagnosis, and (2) likely acquired HIV in the U.S. METHODS: We interviewed APLWH from 2014 to 2017 and estimated the proportion with post-migration HIV acquisition based on clinical data, HIV testing history, immigration date, and behavioral data. RESULTS: Of 179 participants, 113 (63%) were women. Less than half (44%) reported a negative HIV test prior to diagnosis. Among 142 (79%) participants with sufficient data to evaluate post-migration HIV acquisition, we estimate that 29% acquired HIV post-migration. Most APLWH acquire HIV prior to immigration. DISCUSSION: Approximately one-quarter of APLWH acquire HIV post-migration and HIV testing is infrequent, highlighting the need for prevention efforts for African immigrants in the U.S.

HIV/AIDS among African-born residents in the United States.

The number of African-born residents living in the United States (US) increased by more than 750 % between 1980 and 2009. HIV diagnosis rates in this population are six times higher than estimated incidence in the general US population. African-immigrants with HIV are also diagnosed at later stages of infection than US-born residents, but they paradoxically have lower mortality after diagnosis. There are higher rates of HIV among women, higher rates of heterosexual transmission, and lower rates of injection-drug-use-associated transmission among African-born residents in the US relative to the general US population. Despite this distinct epidemiologic profile, surveillance reports often group African-born residents with US-born Blacks. The high rates of HIV among African-born residents in the US combined with increasing immigration and incomplete surveillance data highlight the need for more accurate epidemiologic data along with appropriate HIV service programs.
