摘要
The reproductive ratio, R-0, is a fundamental quantity in 流行病學, which determines the initial increase in an infectious 疾病 in a susceptible host 族群. In most 流行病學c models, there is a specific value of R-0, the 流行病學c threshold, above which 流行病學cs are possible, but below which 流行病學cs cannot occur. As the complexity of an 流行病學c model increases, so too does the difficulty of calculating 流行病學c thresholds. Here we derive the reproductive ratio and 流行病學c thresholds for susceptible-infected-recovered (SIR) 流行病學cs in a simple class of dynamic random 網絡s. As in most 流行病學ological models, R-0 depends on two basic 流行病學c parameters, the 傳播 and recovery rates. We find that R-0 also depends on 社會 parameters, namely the degree distribution that describes heterogeneity in the numbers of concurrent contacts an
