12th Summer Institute in Statistics and Modeling in Infectious Diseases (SISMID)


Module 9: Contact Network Epidemiology

Session 3: Mon Jul 20 to Wed Jul 22

Module dates/times: Monday, July 20; Tuesday, July 21, and Wednesday, July 22. Live sessions will start no earlier than 8 a.m. Pacific and end no later than 2:30 p.m. Pacific, except for Wednesdays. For modules that end on Wednesday, live sessions will end by 11 a.m. Pacific. For modules that start on Wednesday, live sessions will begin no earlier than 11:30 a.m.

Prerequisite: Previous programming experience in some language is expected.

Recommended but not required: Programming will be in Python.

Interpreting population interactions as contact networks provides powerful mathematical and computational frameworks for modeling infectious diseases.  This course introduces network concepts (e.g., nodes, degree, clustering, and modularity), and analytical and simulation-based approaches to contact network epidemiology. We will discuss both idealized and empirical networks and how modeling assumptions affect the tractability of different methods.

Students will use simple analytical models to predict disease properties such as threshold conditions, final sizes, epidemic probability, and epidemic dynamics.  They will use the Python programming language and NetworkX software library to represent and analyze networks, construct epidemic simulations, and model various intervention strategies.
