Climate Change and Risk of Leishmaniasis in North America: Predictions from Ecological Niche Models of Vector and Reservoir Species

Leishmaniasis, a parasitic disease spread by the bite of the sandfly, is indigenous to México and the state of Texas, and has begun to expand its range northward. The models developed as part of this study predict that climate change will exacerbate the ecological risk of human exposure to leishmaniasis in areas outside its present range in the United States and, possibly, in parts of southern Canada.  Further expansion to the north may be facilitated by climate change as more habitat becomes suitable for the disease's vector and reservoir species. This report suggests the adoption of measures to monitor and control leishmaniasis, such as surveillance north of Texas as disease cases spread northwards, and other vector and reservoir control strategies.
