Description: This paper fits a logistic model to the actual data of cumulative cases from the 2003 SARS outbreak. The model proves a good fit for the four areas examined: China [mainland], Canada, Hong Kong and Singapore. Explanatory variables are then incorporated to link the model parameters to economic and demographic indices of areas hit heavily by SARS. The work enables prediction of the future behavior of SARS or other epidemics should they ever strike again.
