Table 2 Outcomes of isolation control policy scenarios on the basis of the expected reproductive number Re, as computed by running the agent-based simulation from 17 April to the mid-June 2015 (keeping all other values of the model parameters fixed). Sparser density refers to a per cent reduction of the expected density of the contact network compared with the 0.63 value that was estimated for the second period (18 February–17 April 2015)
