Figure 4. WNV transmission risks for each different mosquito species estimated from the 12 sampling sites for birds, horses and humans.

For localities with the same estimates dots have been slightly displaced horizontally to avoid complete symbol overlapping. Solid circles indicate those mosquito species and sampling sites in which WNV has been reported in mosquitoes (Vázquez et al. [20], [21]). Estimates are reported for 4 localities for Cx. modestus, 4 for Cx. perexiguus, 5 for Cx. pipiens, 10 for Cx. theileri, and 10 for Oc. caspius. One was added to all estimates to allow plotting on a log10 scale.
