Table 1 Sub-model details for our multi-faceted ecological model for WNV R₀. The two transmission steps (Column 2) of WNV’s life-cycle are: mosquito to bird (M-to-B) transmission, i.e. transmission from an infected mosquito to a susceptible bird; and bird to mosquito (B-to-M) transmission, i.e. transmission from an infected bird to a susceptible mosquito. Citations accompany data available in Additional file 2; details on data extraction can be found in [6]
