A Conceptual Model for the Impact of Climate Change on Fox Rabies in Alaska, 1980–2010
The direct and interactive effects of climate change on host species and infectious disease dynamics are likely to initially manifest at latitudinal extremes. As such, Alaska represents a region in the United States for introspection on climate change and disease. Rabies is enzootic among arctic fox...

The direct and interactive effects of climate change on host species and infectious disease dynamics are likely to initially manifest at latitudinal extremes.
