"Quantitative models and their appraisal in the study of infectious diseases"

In the study of infectious diseases, the most important function of models is to order our thoughts and sharpen our vague intuitive notions, to understand what must or might happen. Models always involves a compromise between realism and the tractability of mathematics. The choice of what is put into a model and what is left out depends on the purpose of the model, such as whether it is to gain insight into a specific question (tactic models) or to address general issues and detect general patterns (strategic models). Models come with different types, such as individual-based (also known as agent-based) models versus population-based (also known as phenomenological) models, stochastic versus deterministic models, static versus dynamic models, and mathematical versus statistical models. In public health practice, it is becoming increasingly frequent to encounter literature that involves some kind of models. Therefore it is crucial to have good awareness of the different types and different purposes in order to develop appropriate appraisal framework of these model applications. This talk will provide examples addressing each of the above topics based on my 20-year experience as a manager of a unit with keywords "modelling, projection and risk assessment" on its title in the fields of infectious diseases surveillance, epidemiology and prevention research.
