Parameterization used to model the three transmissibility scenarios (low, moderate and high) to estimate the risk of autochthonous Zika virus transmission and their data sources.

Transmissibility scenario
Parameter	Low	Moderate	High	Data source
Number of female mosquitoes per person	0.85	0.85	0.85	[37]
Number of bites per mosquito per day	0.3	0.3	0.3	[35]
Average duration of human infectious period (days)	5	5	5	[30,31]
Average vector longevity (days)	27	27	27	[35]
Average proportion of vectors surviving the extrinsic incubation period	0.89	0.89	0.89	[35,36]
Effective transmission rate from human to vector	0.8	0.9	1	[39]
Effective transmission rate from vector to human	0.2	0.4	0.6	–
