Figure. Probable migration route of imported malaria cases described in study of effects of political instability in Venezuela on malaria resurgence at the Ecuador–Peru border, 2018. A) Locations of the 4 countries along the migration route in South America; B) El Oro Province and Tumbes Region on the Ecuador–Peru border. The city of Huaquillas, Ecuador, is 70 km southwest of Machala, the location of the single autochthonous malaria case in this province. Huaquillas is the primary border crossing from Ecuador into Peru. Tumbes, the source of the 3 autochthonous cases in Peru, is the capital of Tumbes Region and is 22 km from the border. Dashed line in panel B broadly denotes the migration route taken from Venezuela through Colombia and Ecuador to Peru. Note the proximity of these countries and additional potential malarial resurgence through migration to Central America, the Caribbean, and the United States.
