The Kermack-McKendrick model was once popularly used to study the dynamics of these three quantities. For 10 points each:
[10h] Name these three quantities that name a series of compartmental models, some of which also consider vital dynamics. In some expanded models, exposure is tracked along with these three quantities.
ANSWER: number of individuals who are susceptible, infectious, and recovered [accept S in place of “susceptible”; accept I or infected in place of “infectious”; accept R in place of “recovered”; accept SIR models; accept SIRE models; accept answers in any order]
[10e] In the Kermack-McKendrick model, the sum of the number of susceptible, infected, and recovered individuals adds up to this quantity. This quantity is the number of individuals living in an area at a given time.
ANSWER: population size [accept total population; prompt on N]
[10m] In 1932, Kermack and McKendrick added imperfect immunity and migration coefficients to their model to improve their ability to model diseases of this kind. Diseases of this kind display a “baseline” level of prevalence.
ANSWER: endemic diseases
