In this module, we will discuss different types of transmission and then focus on direct transmission, and how this affects ID dynamics.

Learning Outcomes

In this module, you will learn to:

  • Assess how different modes of direct transmission affect ID dynamics.

  • Contrast the difference between density- and frequency-dependent transmission.

  • Predict how population size impacts ID dynamics for different types of transmission.


In this video from the “Epidemics MOOC”, Marcel Salathe provides an overview of different types of ID transmission.
