269328 Compartmental complexity: Variations of the SIR model

Saturday, October 27, 2012 : 10:00 AM - 10:30 AM

Not all diseases can be easily described using the simple three-stage framework of the SIR model, yet many can be well described with other, slightly more complex compartmental models. This presentation will provide several examples of “SIR-type” models used in practice. These include models with vaccination, immunity or latent periods, and models of vector borne diseases. Again using the familiar framework of popular culture horror films, we will explore these models, how they relax some of the assumptions of the SIR model, and what assumptions still remain.

Learning Areas:
Basic medical science applied in public health
Epidemiology
Planning of health education strategies, interventions, and programs
Protection of the public in relation to communicable diseases including prevention or control
Public health or related research
Systems thinking models (conceptual and theoretical models), applications related to public health

Learning Objectives:
1. Discuss the differences and similarities between more complex compartmental models and the basic SIR model. 2. Explain how to choose what model structure to use. 3. Compare the assumptions and data requirements of different types of compartmental models.

Presenting author's disclosure statement:

Qualified on the content I am responsible for because: I am qualified to present the proposed topic because I have previously presented on the topic of using zombie outbreaks to teach infectious disease modeling at previous (2010) APHA conferences, as well as organizing and running the proposed institute during the 2011 APHA Annual Meeting in Washington, DC. I also have extensive experience with epidemiological modeling, and have extensively published on applications of popular culture to mathematical modeling.
