Question: As an epidemic spreads through a population, the number of infected people, I, is expressed as a function of the number of susceptible people, S, by
I = k ln (S/S0) - S + S0 + I0, for k, S0, I0 > 0
(a) Find the maximum number of infected people.
(b) The constant k is a characteristic of the particular disease; the constants S0 and I0 are the values of S and I when the disease starts. Which of the following affects the maximum possible value of I? Explain.
• The particular disease, but not how it starts.
• How the disease starts, but not the particular disease.
• Both the particular disease and how it starts.
