We develop a compartmental mathematical model to address the
role of hospitals in severe acute respiratory syndrome (SARS) transmission
dynamics, which partially explains the heterogeneity of the epidemic. Comparison of the effects of two major policies, strict hospital infection control
procedures and community-wide quarantine measures, implemented in Toronto
two weeks into the initial outbreak, shows that their combination is the key to
short-term containment and that quarantine is the key to long-term containment.

Abstract
