Time since last negative HIV test among men who have sex with men and people who use injection drugs in British Columbia 2006–2011

摘要

Canadian surveys of men who have sex with men (MSM) and people using injection drugs (IDU) demonstrate that most have tested for HIV at least once, but that half or fewer have done so in the previous year. To better inform targeted HIV testing guidelines for these populations, we derived estimates of inter-test interval (ITI) for persons newly diagnosed with HIV in British Columbia (BC) between 2006 and 2011, and assessed variables associated with longer ITI among MSM and IDU.
