Websame temporal incidence and prevalence patterns as the population-level model; we use our ILM to directly calculate the average number of secondary infections (i.e., R 0). Surprisingly, we find that this value of R 0 calculated from the ILM is very different from the epidemic threshold calculated from the population-level model. Webto note that R 0 is a dimensionless number and not a rate, which would have units of time−1. Some authors incorrectly call R 0 the “basic reproductive rate.” We can use the fact that R 0 is a dimensionless number to help us in calculating it.
