The distribution of the number of people a carrier infects (Eq. (8)) for 3 combinations of \({n_{c}}\) (the mean number of contacts per day) and \({\beta _{i}}\) (the average transmission probability per day) that result in \({R_{0}}=3\) (see Tab. 1) (left) and for a fixed \({n_{c}}\) but different social structures (right). Default values for the infection probability curve are used, \({\eta _{as}}=1\), and no interventions are applied. Compared to a Poisson distribution with mean of 3, the distribution is over-dispersed
