Factors Associated With Recent HIV Infection Among Newly Diagnosed Cases*
J Vik, CP Archibald, J Kim
Ottawa, ON
*Objectives:* To identify the proportion of and factors associated with recent infection among a subset of newly diagnosed HIV infections reported to the Public Health Agency of Canada (PHAC).
*Methods:* Leftover sera from 3,087 cases of HIV infection diagnosed between 1999 and 2005 and sent by provincial laboratory partners to PHAC were tested using the serologic testing algorithm for recent HIV seroconversion (STARHS). Samples were classified as recent infection (within 170 days prior to sample collection) or established infection (greater than 170 days) by one of two modified EIA tests (Abbot 3A11or bioMèrieux Vironostika HIV-1-LS). Chi-square tests were used to compare characteristics among persons with recent vs established infection; multivariate analysis results will also be presented.
*Results:* The overall proportion of recent infections in this subset of new HIV diagnoses was 27.4% (847/3,087).
Factors significantly associated with recent infection were age (p < 0.0001), race/ethnicity (p < 0.0001), exposure category (p < 0.0001) and gender (p < 0.005). Recent infection was diagnosed more frequently among persons <20 years of age, Aboriginal persons, persons who acquired HIV by injecting drug use, and women. The lowest proportions of recent infection were among persons aged ³50 years, persons of black ethnicity, and persons in the endemic exposure category (indicating origin from an HIV-endemic country).
*Conclusions:* While the data included in this analysis are not representative of all newly diagnosed HIV infections in Canada, the results have important implications for HIV prevention. The lower proportion of new infections identified among certain groups may indicate less frequent HIV testing and care-seeking behaviour in these populations and/or a reduced awareness of HIV risk.
