The CDC's website on climate change and public health offers the background on why the spread of infectious disease is likely to change in the future. A special section on vector-borne diseases outlines how global warming could lead to the re-emergence of diseases such as dengue fever that have nearly been eradicated in some countries. It links to both the CDC's own program on these diseases as well as further reading material.

The EPA regulates the US government's environmental activities and enforces related legislation. As this website shows, it also undertakes research on the links between human health and the environment. Here the agency summarises some of the key research on climate change and health, including vector-borne disease. Although much of the agency's research does focus on the United States, its studies on how global warming will impact air quality and pollution, for example, are likely to be useful around the world.
