Exercise 1

Calculate the population changes from Equations (13.1) to (13.3) in a hypothetical host-parasite system. The parameters for the interaction are: ? = 0.025 (transmission rate) and ? = 0.01 (recovery rate). Start the population with 500 susceptibles and 5 infecteds, and investigate how the dynamics would change if ? increased to 0.040 or 0.060.
