Many infectious 疾病s spread through 族群s via the 網絡s formed by physical contacts among individuals. The patterns of these contacts tend to be highly heterogeneous. Traditional "compartmental" modeling in 流行病學, however, assumes that 族群 groups are fully mixed, that is, every individual has an equal chance of spreading the 疾病 to every other. Applications of compartmental models to Severe Acute Respiratory Syndrome (SARS) resulted in estimates of the fundamental quantity called the basic reproductive number R-0-the number of new cases of SARS resulting from a single initial case-above one, implying that, without public health intervention, most outbreaks should spark large-scale 流行病學cs. Here we compare these predictions to the early 流行病學 of SARS. We apply the methods of contact 網絡 流行病學 to illust
