Agent-based modeling is often referred to as a “bottom up” micro-simulation method, in which population-level outcomes are generated from the behaviors and interactions of individual agents. Agent-based models are useful for simulating the transmission and evolution of health outcomes that are contagious, including (but not limited to) infectious diseases. In this talk, I will describe an agent-based model that simulates HIV transmission in a dynamic network of men who have sex with men (MSM). I will present preliminary results of a study that uses this model to evaluate the hypothetical effectiveness of a novel, long-acting preexposure prophylaxis therapy to reduce HIV incidence among MSM.
