to the editor: Several readers have contacted us regarding our article on vector-borne diseases, graciously identifying a point in our paper that requires clarification.

Our intent was to emphasize that Zika virus, which is spread by the Aedes albopictus mosquito, whose range extends to northern parts of the United States,¹ presents a potential risk beyond the warmer southern regions of the country. However, in emphasizing this, we inadvertently gave the impression that this is the only, or most important, species of Aedes mosquito capable of spreading the virus. Aedes aegypti mosquitos feed only on humans, which may make them more efficient vectors.¹
