The following inferences can be drawn from the resulting relative risk map (figure). First, if A aegyptiis the only competent Zika virus vector, then risk is geographically restricted; in North America to Florida, Louisiana, and Texas. Second, if A albopictus is a competent vector, then there is risk of autochthonous transmission cycles in Canada, Chile, much of western Europe, as well as south and east Asia. Third, for all these areas, the risk compounds that from flights originating in other areas historically endemic for Zika virus.
Risk map for spread of Zika virus:
The circles depict the top 100 cities to which Zika virus might be imported from current infected regions of Latin America and which have suitable habitat for Aedes aegypti or Aedes albopictus in the surrounding region. The size of the circle is the estimated relative risk. Solid red indicates the risk from A aegypti alone. Open circles indicate total risk from both species. The inset shows the status of south Florida, the Caribbean, and nearby areas in more detail.

These results underscore Ayres'1 point that the vector competence of the various potential mosquito species should be a matter of immediate quantitative assessment.
