Fig. 4.

Autochthonous and imported cases of ZIKV around the world from 2015. ZIKV was first introduced to the Americas (Brazil) from the Pacific Island (indicated as red dotted circle with red arrow). From Brazil, the virus then spread to countries in South America, Central America, the Caribbean, and off the cost of West Africa (Cape Verde). Countries with only imported ZIKV cases, from the Americas, are shown in purple color. Countries with both mosquito-transmitted and imported cases are shown in different colors with an estimated number of suspected ZIKV cases in the respective countries. Countries with white colors have not reported any imported cases since 2015 (numbers correct as of September)
