  1. Sensitivity of the R estimates to different assumptions for the serial interval was examined; Three pandemic waves were simultaneously fitted assuming a large number of susceptible individuals but the statistical details were not given;§Parameter estimates from previous work were shown [40], but these did not match the assumed parameter values given in the Table; The epidemic was observed in a community with closed contact (i.e. military camp).
