Module 3 Flashcards
Name six reasons to model infectious diseases.
What are acute and chronic diseases?
What is the SIR framework? What are the parameters that guide the transitions?
What does the force of infection imply?
What are the two possible definitions of lambda?
What does the force of infection mean in discrete time formulation?
What does the force of infection mean in continuous time formulation?
What is the definition of a stock and a flow?
How are stocks and flows linked?
What is the Naive SIR model?
What are the fixed points of the Naive SIR model?
Solve the Naive SIR model.
What is a Phase Plot?
What is the mass action and density dependent formulations of the rate of infections of the SIR model? What does it depend on?
What do the Frequency and Density dependent formulations depend on? When do these differences matter?
How is the frequency dependent transmission term derived?
What are the SIR equations? (X, Y, Z)
What are the SIR equations? (S, I, R)
What is the Threshold Phenomenon?
What is Epidemic Burnout?
What is the SIR model with demography? What is the idea of this model?
What are the fixed points of the SIR model?
What is the equilibrium of the SIR model (with demographics)? When is it stable?
Why is the SIR model with demographics like a damped oscillator?
What is done in stability analysis?
- Fixed points (i.e. dR/dt = 0)
- We use the Jacobian to determine what directions things are pushed at the fixed points

What is Numerical Integration? What is a conceptually very simple solving method? How does it work? What is a better alternative?
What is the SIR model with death? How does the parameter rho impact the results?
How is the SIR model rewritten for an always deadly disease?
What are SIS models? How are they rewritten from the SIR model?
What are SIR models with waning immunity? How is it rewritten from the SIR model?
What is the SEIR model? What are the differences to the SIR model? Why may this be helpful?
How are infections with a carrier state modelled?
What are residence times?
The time a individual spends in a category.
What is the Box-carr method?
