Modeling the Spread of an Epidemic | By developing a computer model of the spread of an infectious disease‚ the student develops an understanding of the role of the infection rate and the removal rate on the spread of the disease. The Threshold Theorem of Epidemiology claims that the extent of spread of an epidemic can be predicted if three values are known: initial number of susceptible people (S(0))‚ the infection rate (K)‚ and the removal rate (by quarantine or cure) (Q). The extent of the
