A new virus strain. Epidemics eventually run their course, leaving a large number of recovered individuals. However, new strains evolve that can get past the immunity developed to previous strains. This is called immune escape. The public health department for your town has created an SIR model to predict the effects of this year's new strain of flu. The SIR equations are given by: S = -0.0000002SI, I' = 0.0000002SI - I/15, R' = I/15. The initial values at t = 0 are thought to be: S(0) = 2,000,000, I(0) = 21,000, R(0) = 15,000.
  1. Using the initial rates, use the SIR model to find S(1), I(1), and R(1).
  2. Using the SIR equations, calculate the rates of change S', I', and R' when t = 1, and then use these values to determine S, I, and R when t = 2.
  3. In the previous part, you found S, I, and R when t = 2. Using these values, calculate the rates S', I', and R' when t = 2, and then estimate the values of S, I, and R when t = 3.
  4. Double the time step. Go back to the starting time t = 0 and to the initial values:
