HAART Reduces HIV incidence in IDUs % Injecting % on HAART Community pVL HIV Incidence G Kirk, …, D Vlahov for the Alive Cohort, CROI 2011
HAART Reduces HIV incidence in IDUs • From 1997, HIV incidence decreased by 74% (IRR 0.26, 0.08-0.81) for each log decline in community pVL • In a separate model, HIV incidence decreased by 5% (3-8%) for each 1% increase in the proportion of HAART treated patients • For the entire follow up period, for each 1% decline in the proportion of HIV+ patients actively injecting, there was a 3% decline in HIV incidence. - However, this effect was largely restricted to the pre-HAART era G Kirk, …, D Vlahov for the Alive Cohort, CROI 2011
