Modeling the population-level impact of HIV prevention in C么te D鈥橧voire

ALL ARE WELCOME

Abstract:

Despite a long-standing commitment to curb its epidemic, C么te d鈥橧voire has the highest recorded HIV prevalence in West Africa. Soon after the first AIDS case was reported in 1986 in Abidjan, a national response was mounted and a range of interventions have been scaled up during the 1990s and 2000s to address this health crisis. Most notably, these include: condom interventions, antiretroviral therapy (ART), and prevention of mother-to-child transmission (PMTCT) activities. Today, the UNAIDS aims to 鈥渆nd the AIDS epidemic as a major global health threat by 2030鈥� by considerably scaling up testing and treatment access (i.e., the UNAIDS 90-90-90 objective). In order to better understand the epidemic and estimate the population-level impact of different interventions, I developed a detailed age-stratified dynamical model of HIV transmission, parameterized it using local data, and fitted it to prevalence and programmatic data using a Bayesian framework. In this talk, I will (1) briefly discuss the role of models in impact evaluation, (2) assess the population-level impact of past HIV interventions (condoms, ART, and PMTCT) in C么te d鈥橧voire, and (3) estimate the effect on HIV transmission of accelerating the national response to reach UNAIDS 90-90-90 objective by 2020.
