Zika map

Many US cities face potential risk in summer of low, moderate, or high populations of the mosquito species that transmits Zika virus (colored circles). The mosquito has been observed in parts of the United States (shaded portion of map) and can establish populations in additional cities because of favorable summertime meteorological conditions. In addiiton, Zika risk may be elevated in cities with more air travelers arriving from Latin America and the Caribbean (larger circles).
