BACKGROUND Expanding access to highly active antiretroviral therapy (HAART) has become an important approach to HIV prevention in recent years. Previous studies suggest that concomitant changes in risk behaviours may either help or hinder programs that use a Treatment as Prevention strategy. ANALYSIS We consider HIV-related risk behaviour as a social(More)
Realizing the full individual and population-wide benefits of antiretroviral therapy for human immunodeficiency virus (HIV) infection requires an efficient mechanism of HIV-related health service delivery. We developed a system dynamics model of the continuum of HIV care in Vancouver, Canada, which reflects key activities and decisions in the delivery of(More)
HIV remains a serious public health problem in many marginalized communities. We develop a network model of the HIV epidemic affecting injection drug users and female sex workers in the Downtown Eastside neighborhood of Vancouver, Canada, calibrated using data from public health surveillance and cohort studies. Many HIV positive individuals are unaware of(More)
The research below is about modelling complex social systems, and in particular applications of Cellular Automata. This is a collaboration of variety of initiatives such as MoCSSy, CSMG, IMPACT-HIV at the IRMACS centre in Simon Fraser University and the BC Centre for Excellence in HIV/AIDS. 1 Abstract Injection drug users (IDU) who share needles are at high(More)
Creating individualized within-host multiple phase disease models of HIV-1 infection has long been a goal of mathematicians and biologists. The challenge is in trying to build models that are representative of the disease, include realistic parameter estimates, and are able to incorporate a changing model structure. In this paper, we propose a fitting(More)
