Process models offer opportunities to explore the effectiveness of different program and policy alternatives by varying input behaviors and model parameters to reflect programmatic/policy effects.
Traditional theoretical HIV models set modeling parameters a priority and a small change in model parameters often gives widely varying results for the same behavioral inputs. The Asian Epidemic Model (AEM) has been designed to reflect the primary groups and transmission modes driving HIV transmission in Asia. The user adjusts AEM modeling parameters until HIV prevalence outputs from the model agree with observed epidemiological trends.
The AEM is a semi-empirical model, which has worked well in Asian settings. It provides a useful tool for policy and program analysis in Asian countries.
