Summary of the parameters of the model with their notations, the range of values in literature (from Luz et al. 2003), the range of values used to test the homogeneous model and the values for the EI case. EI, Easter Island; EIP, extrinsic incubation period; IIP, intrinsic incubation period.(* in the 5% infested households, no vector at all elsewhere, which correspond to 1.5 vectors per host in the whole population.)
